My legacy system works just fine. What is the need for IBM i modernization?
My legacy system is reliable. Why is there a need to modernize it?
7/10 of our customers preach about how their legacy IBM i AS400 system is in great condition and why it doesn’t need an upgrade.
But, it’s our job to make them aware of the problems that may cross their paths in the near future.
Are you a proud IBM i user? This one is for you.
This piece will walk you through all the odds that you may face and why you should consider modernizing your IBM i applications.
Let’s begin!
My System Extends Pathetic Customer Experience!
Customer experience has a vital role to play in business today.
No matter how excellent your product/service is if you are offering a mediocre customer experience. You are creating room for your competition to outplay you, if not prioritizing customer experience.
For enterprises, it is time critical to touch ground zero and indulge with every customer/user to understand the effectiveness of the user interface offered. But, that doesn’t mean that customer/user experience isn’t essential as a parameter for modernization!
It’s the most crucial parameter as customer-facing/user-facing applications significantly impact buying decisions/productivity.
Here’s how IBM i modernization can enhance your customer experience:
- Eradicate service-level interruptions and extend a compelling buying journey
- Enables your business to create interfaces aligned to ever-changing customer expectations
- Empowers you to understand the likes and dislikes of the customers and make the necessary changes to the experiences
- Enables you to respond faster and more effectively to the customer queries
Modernized user interfaces work seamlessly for the internal business team and add up to the productivity.
My System is Exposed to Security Threats!
“When you are an IBM i user, security is not a big concern!”
Well, we agree that IBM i systems are the most robust and reliable systems that offer you great security.
But, with the changing times cyber-attacks, data leakage, and unauthorized access control have become worrisome factors, ever for IBM i users.
72% of IBM i users have listed security as the top concern.
To safeguard your data, IBM i modernization can be a good move. It’s more like revitalizing the system and diminishing the possibilities of data leakage.
The right IBM i modernization firm, well-versed in your domain of work, can help you set up indomitable security standards to hunt down ruinous security threats.
My Current Development Team/Partner Lacks Technical Expertise!
The biggest disadvantage of relying on legacy applications is the ever-shrinking talent pool.
IBM i AS400 is an undisputed powerhouse of technology, still empowering thousands of mission-critical projects.
The sad part is professionals who have worked their brains to make IBM i the most reliable and secure platform are retiring, faster.
Still, there are IBM i modernization companies that claim to have the right set of talent available for you. They promise a smooth transition from legacy applications to the modern but will cost you an earth and a half.
A deal that every IBM i user wants, but no one would wish to pay for. Reason – the costs are unrealistic.
You may ask – “Then, how to find the IBM i AS400 professionals?”
Find the right IBM i modernization companies who have got their hands dirty and made the rock turn. Get in talks with a few, and ask for customer testimonials and client feedback.
Hear from the IBM i users they have worked for and then decide if these guys can do it for you or not!
I am Unsure if my Current System will Support the Scalability Metric
Enterprises that use legacy applications, aren’t they eligible to scale?
Well, of course, they are.
But they often fail to scale.
Reason – Legacy Applications!
How? It’s very simple.
After a point, the processing capacity or the hardware power starts to fall short. And this inability to pass the bar holds you back from scaling up.
IBM i modernization empowers your IBM i applications with a modern technology stack, process-level automation, and advanced security, and lets you handle a large volume of data with ease.
The biggest advantage that IBM i modernization brings is performance enhancement. This enables you to have more system users and process more data in a stipulated time frame.
My Current System Lacks Data Control & Management
Data is an invaluable asset today.
If you are not able to manage your enterprise data effectively and your IBM i system has weak links, you are putting your data at risk!
What amount of data you have and who has gained how much access control over your data can be a severe security threat to your business.
It is advised to have limited user profiles with limited data access rights to avoid data breaches and data leakages.
When a user creates a new profile on IBM i, the system by default sets the username as a password. It’s known to all.
And, according to a study conducted by Help Systems – 24% of systems have about 100+ profiles using default passwords.
This is a serious threat and can lead to chaos if not treated in time.
IBM i modernization is an opportunity that you can use to define data control and management standards. You can define who gets to see what and in what authority.
There is nothing more fortunate in business than the security of data.
I am Worried that I Might Lose the Competitive Edge & the Current Market Share!
Customer demands are on the rise.
The market is shifting at a pace that one could have never imagined.
If you are thinking that I am good with my pie of market share, you are already out of the race.
Gaining a competitive edge is no longer a part of the annual goal setting. Today, it has become a necessity to survive in the market.
So, the next time when you host the annual goal-setting meetup, it should be about being the market leader and not about sharing the market.
What’s stopping you from becoming a market leader?
- Don’t have the top-notch offering in the segment? – Make it happen
- Don’t have the right resources? – Hunt them
- Don’t have modern technology? – Wait! Aren’t you already using IBM i System?
No need to invest in modern technology, just find the right IBM i modernization company and modernize your legacy system.
Still not convinced about modernizing your IBM i applications? Let’s take a closer look at why you must do that, today.
Why do You Need to Modernize Your iSeries Applications?
AS400/i-Series systems have been in use for over three decades now. Even in 2023, despite being a reliable technology, it has its drawbacks.
Organizations that emploddy AS400 software applications have issues from time to time, which could probably be related to performance, user experience, or both.
The following are some of the key reasons why you should definitely consider modernizing your IBM iSeries AS400 software applications right now:
Staffing
Because many AS400 software application systems are decades old, the IT specialists who manage them are nearing retirement age.
Companies and organizations’ CTOs or CIOs cannot allow such obsolete software to function independently and unsupervised. Even with the most advanced automation, such software necessitates manual intervention.
As a CTO or decision-maker in an organization, you can choose to outsource maintenance to AS400 software development companies.
UX/UI
One of the most significant disadvantages of using an AS400 iSeries system is the standard green screen on which users must operate.
Modernizing these green screens to reflect the more modern GUI (graphical user interface) while keeping all of the legacy RPG software’s benefits is an appropriate approach.
Read More About – Why AS400 Green Screen to GUI Is a Strategic Investment in 2024?
Operating System
OS 7.2 and even 7.3 seem to have become outdated as newer operating systems like 7.4 take over the iSeries realm. IBM formally ended up providing TRs (technology refreshes) and PTFs (program temporary fixes) for version 7.2 users back in April 2021.
Organizations with Power Systems can upgrade to 7.3 or 7.4, which will have AS400 support services for years to come.
Organizations utilizing non-Power Systems, on the other hand, must either modernize their technology to accommodate newer operating systems or face complications.
Manual Intervention
Automation is another critical issue to consider while thinking about modernization. The operations that run on these outdated systems, as well as the server, necessitate manual intervention. As a result, any firm that relies on legacy systems must implement a solid automation solution.
Lack of Integration
Due to a lack of integration with advanced technology, AS400/i-Series applications are segregated from other programs.
The Hardware Conundrum
The decision-makers who are sceptical about cloud migration will need to choose the most recent power system or higher to gain all of the benefits, as outdated ones lack AS400 support services and security.
Security Concerns
Despite the fact that IBM iSeries AS400 systems are quite robust and reliable, security threats might render your legacy software systems vulnerable if you are running an outdated application, database, or operating system.
The Evolution of iSeries Systems
iSeries systems, AS/400, have been around since the 1980s. They were designed for stability and reliability, making them a popular choice for businesses across various industries.
But as technology advanced at a breakneck speed, these systems started showing their age. They struggled to integrate with newer technologies, making it difficult for businesses to keep up with the digital transformation wave.
Challenges with Legacy iSeries Systems
Legacy iSeries systems pose several challenges in today’s dynamic IT landscape. For starters, they often operate in silos, making it difficult to share data and collaborate with other systems.
They also need more flexibility and scalability to support rapid business growth. Plus, maintaining and upgrading these systems can be a costly affair, eating into your IT budget.
The Impact on Business Operations
These challenges can have a significant impact on your business operations. They can lead to inefficiencies, higher operational costs, and missed opportunities for innovation.
These legacy systems can hold you back in a world where agility and innovation are key to staying competitive.
But don’t worry; there’s a solution: iSeries modernization. The process can help you overcome these challenges and unlock the full potential of your iSeries systems.
Now as you understand why you must modernize your iSeries applications, let’s take a closer look at what all legacy application modernization includes & challenges involved.
What does Legacy Application Modernization Means?
Legacy application modernization means upgrading an existing enterprise framework with more modern, agile, scalable, highly accessible, and secure solutions.
Application modernization means redesigning existing business applications to meet growing digital needs.
Upgrading your old apps with new architecture and features gives them a new life, prevents them from becoming obsolete, and creates attractive business value.
Let’s take a closer look at the key challenges faced during legacy application modernization.
Challenges of Legacy Application Modernization
Legacy application modernization is a smart business move but comes with its own set of challenges.
Let’s understand the key challenges you might face during legacy application modernization journey, and how to tackle them.
Lack of Knowledge
This is the main challenge in updating legacy apps for the following reasons –
- Developers who developed the application are no longer in the organization or connected to the application.
- Functional and technical documentation is missing, irrelevant, or outdated,
- The source code is highly corrected
- Used third-party application/library resources not available.
One possible way to deal with this is to go to code manually and select a function, which is a tedious task since most codes (usually about 30-40% of the entire code base) are redundant or no longer exist.
Heavy Legacy Ecosystem
Each organization has been running its own IT setup, and even today, there are plenty of applications in legacy technology. In such cases, when management decides to update the old footprint completely, it significantly impacts the business.
When we take even a single application to update, the upstream and downstream applications will remain in the old technology, with many old protocols, file formats, etc., and it’s not possible to modernize them in one go.
In such cases, the method of division should be followed. We need to take the critical applications first and then handle the rest.
We may also need to set up some tools and design applications to support legacy practices so that the current business flow will not be affected during the transition period.
After all, apps are updated, legacy fingerprint support can be turned off.
Quality Guarantee
Another challenge is quality assurance, as older applications may have performed better, and newer applications may need to be tested to ensure they function better.
As with every IT project, we need to ensure that all possible test conditions and cases are well defined and pre-set for the testing phase.
User acceptance testing needs to be well-planned and having as many professional users as possible can help ensure the integrity and completeness of a modern application.
A successful component of the legacy modernization project is the involvement of business users from the application search phase to quality assurance.
Performance Achievement
Pure legacy systems like high-performance mainframes, especially in terms of batch processing.
In these cases, legacy applications need to be analyzed to replace existing parts of the code with related COTS products or frameworks. In most mainframe applications, the interface between applications or programs is usually through an intermediate file.
It can be redesigned to pass data directly without any file I/O. Another critical factor in reaching the optimal hardware size.
Data Migration
Most of the older ecosystems would have lived longer if modernization had taken place.
That way, they will have more data through business transactions. In almost all cases, it is up to gigabytes of data, if not petabytes or terabytes, and is usually organized on databases, files of various formats (text, binary), etc. In addition, older systems may use EBCDIC or any other encoding, whereas most modern systems operate on ASCII or ASCII-based encoding.
This adds another dimension to the problem of data migration when it is not organized.
To take care of the differences in coding, there are tools on the market and some ETL plugins that help in easy data migration.
If the legacy application is expected to handle data files with non-contemporary encoding, we need a framework to take it. Older system VSAM files can be migrated to SQL or NoSQL databases.
Now that you are aware of the challenges that you may face during legacy application modernization, let’s understand why companies avoid legacy application modernization.
Why do Companies Avoid Updating their Legacy Applications?
Moving from the convenience of “known and sufficient” to the assurance of efficiency, scalability, and high productivity can be frustrating for many managers.
- How much does it cost?
- How long will it take?
- Do we have the staff resources to make this happen?
Here are some more which we found to be interesting –
The Cost of Modernization and Project Duration will be Higher
Over-budgeting is the weakness of every organization and the nightmare of the project manager. There is a real fear that the existing system will retire on the side of the new platform and incur additional costs in addition to the various advance costs that may or may not be supported. However, it is also myth #1.
The cost of updating the app is not a challenge; Cloud is the biggest money saver in IT. And all other expenses of modernization have to be paid for by the acquired functionality, the extended reach to the customers, and the application interoperability.
Legacy & New Systems May Not Work Smoothly
Updating the app is a daunting task for organizations with large legacy footprints. App updating, in this case, would be pretty more complicated and should be managed carefully. During the update process, my entire work process may stop! This is myth #2.
Application updates can be divided into simple steps to handle multiple applications simultaneously. Business continuity is at the heart of all application modernization technology.
The Integration of On-premises and Cloud Infrastructure will be Extremely Disruptive
When an organization decides to upgrade, they do not want to abandon their existing software and applications that have been created and deployed on their on-premises infrastructure. However, placing some applications in place while others are in the cloud can lead to inefficiency and an operation silo. This is myth #3.
The truth is, on-premises and cloud apps can be rented together and put together to give you a full 360-degree view of the business.
Change Management – Our Workforce can’t Keep Up
Older systems are usually outdated. It is difficult or impossible to find employees who created or were employed on this application.
Because the system is old, it leaves us without the information or skills needed to migrate data from the old system.
The complexity of migrating our old systems to new, modern platforms is beyond our capacity. If the update fails, we risk losing important data. This is myth number #4.
Now, let’s take a closer look at the security risks & challenges during IBM i application modernization.
IBM i Security Risks and Challenges?
One of the most crucial and valid advantages of the IBM iSeries is that it is generally perceived as a secure platform. It is thought to be so because it has strong IBM i security mechanisms and durable hardware and it is supposedly uncommon for a virus to be built to target it.
However, as cyber-attacks become more widespread, IT security must become a larger concern for everybody, including those using the allegedly impenetrable AS400 iSeries.
Data privacy and security have been frequently mentioned in the news during the last decade. No one wants to be in charge of their firm when a high-profile breach occurs. Therefore, the significant legal and reputational ramifications are evident.
When IBM iSeries AS400 implemented tools such as the IFS to integrate platform software applications with Linux and Windows systems, it improved utilization while also increasing IBM i’s susceptibility to possible dangers.
Now, as you are aware of the legacy application modernization risks & challenges, let’s uncover different iSeries modernization strategies.
iSeries Application Modernization Strategies
So, you’re convinced that iSeries modernization is the way to go. But where do you start?
Let’s explore some strategies that can guide your modernization journey.
Cloud Migration: A New Home for iSeries Applications
Think of cloud migration as moving your iSeries applications from a cramped apartment (your on-premises servers) to a spacious, modern villa (the cloud). In this new home, your applications can stretch out, grow, and adapt as your business needs change.
Plus, you can enjoy the perks of living in the cloud, like scalability, flexibility, and cost-efficiency. It’s like upgrading your lifestyle without breaking the bank.
Application Modernization: Revamping Legacy Applications
Application modernization is like giving your legacy applications a makeover. You’re changing their look and feel and improving their performance, usability, and compatibility with modern technologies.
It can involve re-platforming (changing their underlying platform), re-hosting (moving them to a new environment), or even re-architecting (changing their structure or design). The result? Applications that are ready to meet the demands of today’s digital world.
Choosing the Right Strategy for Your Business
Choosing the right modernization strategy is like choosing the right path for your journey. It depends on your specific needs, goals, and resources. Cloud migration is the best fit for you, or application modernization is the way to go.
Or you may need a combination of both. The key is carefully evaluating your options and choosing a strategy that aligns with your long-term vision.
Managing an IBM AS/400 or an i-series environment is no small feat. Not all businesses can afford to spare it and require expertise, time, and resources.
So, what’s the solution? Outsourcing.
Outsourcing your iSeries administration or application modernization to experts can unlock many benefits that propel your business to new heights.
Now as you are aware of different strategies for iSeries application modernization, let’s look at different types of modernization you might want to exercise.
Types of AS400/i-Series Modernization
Modernization is an umbrella term.
It encompasses multiple aspects of your iSeries.
Let’s understand each of them one-by-one.
Front-End Modernization
Front-End modernization solutions entail complete redesigning of your IBM iSeries AS400 user experience by reviving 5250 green screens.
Modernizing your green screens can be accomplished in four ways –
- Screen Re-facing
- RPG Open Access
- Zend PHP Server
- API & UI Framework
Code Modernization
Some organizations continue to employ fixed-form RPG programming rather than free-form code. Although free-form coding is easier to comprehend, many modern language functionalities are not accessible in a fixed format.
RPG fixed form is incompatible with modern coding languages, which are all free form. As a result, they must be re-evaluated into a three-tier modernized code.
Cloud Migration
This method is effective in both ways, particularly when it comes to reliability and security. Migrating all of your data from your AS400 iSeries to a third-party cloud service like Azure, AWS, or Oracle is undoubtedly daunting.
However, cloud companies have improved their reliability in order to provide users with a sense of security. Moving your apps to the cloud reduces server maintenance costs and ensures that your data is secure during IT emergencies.
Methods for transferring your information to the cloud server –
- Application re-hosting (lift and shift)
- Batch job migration
- Application re-engineering
RPA on RPG
Automation enables decision-makers of the companies to focus on more essential work processes and strategies while RPA bots handle routine tasks. Organizations end up saving time and money as a result of this.
When installed for your IBM iSeries AS400 systems, RPA can accomplish the following tasks –
- Data entry
- Data extraction
- Ticket creation
- Machine monitoring
- Reporting
Integration Solution
The modernization of AS400 iSeries software applications will not be complete unless all of your systems are integrated to share data. Most applications running on AS400 frameworks are isolated from other software or systems in the environment.
It occurs because IT leaders are unable to create appropriate system documentation; IT staff are overburdened with several other responsibilities or are unfamiliar with the integration protocols and technologies that support interface.
Here are a few systems with which iSeries can be integrated –
- CRM integration
- SAP Integration
- Mobile application integration
- BI platform integration
Now that you know different ways you can modernize your iSeries applications, let’s look at the key benefits of application modernization.
Benefits of IBM i Application & Data Modernization
To stay competitive, you need to stay updated. An essential aspect of staying current is updating your legacy IBM iSeries AS400 business suite with constantly evolving technology.
This does not mean changing your existing business system. It means integrating the existing IBM AS400 platform with new and emerging technologies. This way, the time, money, and efforts you have already invested will be the same, but you’ll get more ROI.
There are many ways to upgrade your IBM iSeries applications to create new business value and meet your emerging needs. Whether you want to update apps, data, or platforms.
Your IBM iSeries can be updated in three ways –
- Application Modernization
- Data Modernization
- Platform Modernization
Let’s discuss each of these in detail.
Application Modernization
Reconstruct, redesign, or strengthen your IBM i software using a web interface to differentiate business logic from presentation.
What is an Application Modernization?
Application modernization is a process when a company updates or redesigns its existing software to align it with emerging needs in a better way and to extract more value. This usually involves updating the architecture, infrastructure, or key product features.
How to Modernize?
Features of PHP make it ideal for creating a reliable web interface for existing IBM iSeries applications so that it can support more use cases with web and mobile users.
For example, PHP provides DB2 language extensions as well as tools to facilitate seamless integration with XML Service.
Have a look at the three ways for the application modernization process.
The first, and least exhaustive resource, is adding your existing code base and configuration to modern publishing platforms. A modern platform can give you higher scalability, speed, and better resource optimization.
The second option is to enhance your software, add new features, and make it more accessible to modern apps and environments. For example, you can attach a front-end mobile app to your existing mainframe application.
This approach will save development time and reduce costs while maintaining the functionality of your IBM AS400 software.
The third option is to rewrite your old app completely. While this can be time-consuming and expensive, it’s a great option if you don’t want to keep software that is no longer supported or don’t have the knowledge needed to manage outdated applications.
Data Modernization
Unlock the power of your IBM i data by making it easier to use with more trusted applications.
What is Data Modernization?
This is an important point in our journey towards creating a data set that is adaptable and versatile to identify real up-to-date data.
We need to pay attention to the big truth about data: that older data tools can’t handle modern data problems.
The specific data set consists of a large number of steps, such as a large number of tools and integrations, all of which result in operational complications, time delays, and preventive costs.
What is the importance of data modernization?
Data modernization has become a primary concern because it can provide exemplary data experiences that deliver critical and remarkable knowledge, integrate API-driven applications, and respond to the real-time demands of a healthy business environment.
How to Modernize?
The CRUD (Create, Read, Update, Delete) application is a proven way to quickly connect more users with the data they need through the web interface. For example, writing a few lines of PHP-based phpGrid code makes it easier to implement a CRUD application.
Modernizing your data is the fastest way to transform your organization into a data-driven analysis organization.
Benefits of Modernizing Data Platforms
- Provide users with an integrated view of data from multiple sources, make data available to the entire organization with appropriate permissions, and improve data management.
- Provide access to the correct data at the right time, without delaying the process of data volume or data requests to the organization’s employees.
- Allow companies to manage their data governance strategy better. This may include what data is collected under the Data Protection and Privacy Rules, who has access to it, and when the data will “expire.”
- Provide a single access point through modern authentication tools like SSO to ensure authentication for users. That way, you can easily track who has access to the data on the platform.
- Bringing data together from multiple sources for more collaborative and effective decision-making, adding organizational silos.
- Provides benefits to the organization such as low cost, democratized data, low latency, increased access speed, dynamic intelligence and analytics, faster market time, and more.
Platform Modernization
Upgrade your IBM iSeries AS400 platform to interact with new technologies to improve your business processes.
How to Modernize?
IBM iSeries has a long legacy as a solution platform. You can improve the return on investment for your IBM AS400 system by deploying accessible, open-source technologies like WordPress, Drupal, and Magenta. In addition, the open-source enterprise architects provide solutions such as IBM, Apache, Maria DB, and a set of PHP (iAMP) solutions.
Now, that you are aware of the benefits of IBM i application & data modernization, let’s understand web services in IBM iSeries.
The Essence of Webservices in IBM iSeries AS400
Primarily web services are concerned with program-to-program interactions. For example, in IBM AS400 modernization, you can use web services to connect the backend processing system of organizations with markets. Or you can use this for order fulfillment and employee management.
Webservices also supports offerings between businesses and customers, the same as a browser-based internet model. Furthermore, web services also let companies manage daily tasks systematically. However, the selection of web services can be dynamic as per requirements.
Three Stages of Webservices Integration and Interactions
- An application outsourcing services provider develops a new web service and publishes information about the interface.
- Companies use their sources to find application outsourcing service provider. Furthermore, companies check various criteria to select a service.
- The companies then retrieve the information stored with the help of an IBM outsourcing company, and then the company is bound to use the services.
Now, the big question is – “How to enable web services?”
Enabling Web Services
Generally, several new technologies are used for developing web services. Also, developers may reasonably argue that web services can be developed without using any modern technology. But, web services are mainly written using these technologies:
- eXtensible Markup Language (XML) Simple Object Access Protocol (SOAP)
- Web services Description Language (WSDL)
- Universal Discovery Description and Integration (UDDI)
If you want to “Enable Web services,” then you should know about these technologies.
XML
eXtensible Markup Language is an extensible tag language used to describe complex systems in a way that is easy to understand. Webservices rely on XML to a larger extent. XML makes use of textual records instead of binary records. Well, we know that binary records
are faster to process, but in order to set develop a standard in more than
decade, some standard has been defined for using binary records.
Since XML is textual data, the issue of using different hardware and language doesn’t occur generally. And such features make it platform independent. It takes minimal time for a CPU to create and parse XML data. And this adds up to significantly less processing time than necessary to convert software to a binary format.
Also, it would help if you weren’t concerned about XML praising time, as the more important thing is – businesses should talk to each other. And XML enables this conversation.
SOAP
Simple Object Access Protocol (SOAP) is an XML protocol used for describing how a message is developed and sent between the parties included in web services. SOAP is a set of XML tags. With SOAP XML tags, you could outline a remote procedure call (RPC). The external tag is referred to as the SOAP envelope. The process has some parameters and includes return values that needed to be passed. XML tags in the SOAP envelope describe every parameter and the return value.
SOAP envelopes can be delivered through various communication channels. In the current specification of SOAP, it is mentioned that it is used for sending SOAP covers over HTTP (with or without the HTTP extension). Although, the specification makes it clear that other protocols can be integrated within the SOAP architecture. For example, you may send SOAP envelopes via email, i.e., Simple Mail Transfer Protocol (SMTP), or over a messaging product.
WSDL
Web Services Description Language (WSDL) is a kind set of XML tags that can explain the interface to web services. Also, it can be used in IBM AS400 modernization. In terms of features, WSDL is like CORBA’s Interface Definition Language (IDL).)
When a web service is made available to an application outsourcing services provider, it includes the instructions about the parameters that need to be handed at the SOAP request and the parameters needed to be returned. IBM AS400 modernization web service toolkit consists of tools to develop WSDL from existing applications.
UDDI
Universal Discovery Description and Integration (UDDI) is a plan for designated web-based data registries of web services. UDDI is likewise a publicly approachable set of operations of the requirement that permit organizations to register data about web services. UDDI offers SOAP APIs that define the interface of an IBM application outsourcing services provider. You can seek a UDDI registry or look for a company providing certain types of services.
Prior to UDDI, there has been no easy way to gain info about the service offering of an IBM AS400 integrated organization. Also, there was no single point of access to let companies target all feasible buying and selling companions and their offerings. Without UDDI, web services outsourcing partners need to have more than one repository type.
Integrated Webservices for IBM AS400 Modernization
Integrated web services for IBM AS400 modernization enables ILE applications to adopt web services and SOA arena with determination, information, and necessary resources. The conjunction of web services and IBM AS400 technologies can help organizations release conventional business methods and make it easier to enhance, upgrade, and reuse applications and processes beyond the scope.
In today’s fast-paced technology world, APIs are becoming a synonym to the digital refection of an enterprise. You call it web API or web services but getting started with IBM AS400 modernization will be easier than ever with the IWS for IBM i. The bottom line is that today’s flexible businesses require flexible IT setup, and the path to this flexibility is Service Oriented Architecture (SOA).
Features and Benefits
The IBM consulting services provider integrates technologies that support the conversion of the data object into a suitable form and make them ready for export. IBM AS400 iSeries modernization services enable externalization of an ILE program object as web APIs and the consumption of services by an Integrated Language Environment (ILE) object. Such technologies are integrated web services servers for ILE.
But do you know the process of Integrated Web Services Server?
Integrated Web Services Server: The web service engine is integrated into IBM AS400 modernization and converted ILE data object into a service. This integration opens the IBM modernization technology to various implementations, like RPG, COBOL, .NET, Web 2.0, C, C++, and Java.
Features
Easy to Use
The web service server is easy to use as the GUI front end allows the companies to manage and monitor deployed web services.
Leading Edge
The web service server is developed on the powerful and lightweight, integrated application server and best-in-class technologies, SOAP, and REST support.
Small Footprint
Uses Integrated Language Environment (ILE) programming architecture for nominal utilization of IBM AS400 modernization resources.
Benefits
Get Started with No up-front Costs
The integrated web service server is a component of the OS, so companies can get services fast and running and show substantial results in real-time.
Focus on Core Capabilities
Companies don’t require additional hardware setup or skills to deploy their IBM AS400 set up to deploy web services. They can simultaneously focus on providing more value to the customers while the integration process goes on.
Importance of webservices done & dusted? Now, let’s understand why working with an AS400 technology partner provides the right balance during IBM i modernization.
Why Work with an AS400 Partner for IBM i Modernization?
The modern technology that exists today may seem outdated tomorrow as new technologies are emerging every day. IBM AS400 is one such technology introduced 30 years ago and needed modernization.
Now, organizations may get confused in modernizing the application in-house or outsourcing the task. Outsourcing means you can get the process done outside without disturbing the internal process.
You may choose to work in-house, but an organization needs lots of resources, a dedicated team of developers, and many more important things to complete the task. This blog explains why AS400 needs modernization and the importance of outsourcing the job.
Daily, we read about emerging technologies and their potential to rebuild entire organizations. But generally, we focus on one side of it, like back-office etc., and not on the whole business process, say job applications, payment processing, and help desk tickets.
It’s time for organizations to focus on the entire workflow and not just one, as emerging technologies reshape the core business functions. And to help you out in the end-to-end approach of modernizing the overall setup, i Series AS400 services can help you out at every step of the process.
What should I know before I approach an IBM i Modernization Company?
Are you holding back on your IBM i modernization initiative, as you are concerned –
- What if I end up choosing the wrong IBM i modernization partner?
- What if my IBM i modernization partner fails to deliver to my expectations?
- What if my modernizations goals are mistaken by the modernization partner?
See, if you think this way, you are wise and not wrong.
Any wise technology leader would think at least 10 times before they proceed with a strategic technological partnership.
But, how should you navigate this scenario?
Simple, by asking the right questions to yourself, your team, your IBM i users.
Thinking, what questions to ask?
Let’s take a look at a few of them.
What are the current business challenges and possible solutions?
IBM i Modernization isn’t a “One size fits all” approach, you need to understand this first.
Agreed that you are going to rope in the best-in-class IBM i modernization company to do the job for you. If you are fortunate enough, you will also be able to land a firm that carries domain expertise in your field of work.
However, they aren’t acquainted with the system that you are using as you do. No one, believe us no one knows your current system better than you and your users.
Going further, if you want them to understand your system and then figure out the possible solutions, it’s going to eat up more time and budget for sure.
So, what can be done in this case?
It’s always better to have first-hand insights in place before you call upon IBM i modernization.
And, how do you ensure that you draw crisp first-hand insights?
Here’s how you can do that –
- Initiate a centralized communication channel where all the system users can register the system challenges, they are facing.
- Consolidate and validate the challenges registered after a set time window.
- Initiate another survey where system users will be asked to register possible solutions that can put their job at ease for the registered challenges.
- Consolidate and validate legitimate solutions proposed by the system users.
- Besides this exercise, conduct a thorough audit of the legacy system and try to locate the loopholes. There are possibilities that you may also find room for improvement and opportunities to scale the system up.
- Study the systems that your competitors are using. Understand what’s working for them. List what you believe may improve your current system and cut down the rest.
Following these steps, you will have your first-hand insights ready.
Quick Example
Assume, your system is currently being used by 100 users. You identify that your competitors are getting an edge by employing more system users, and you decide to do the same with your system.
You initiate hiring and start pushing the number of system users.
While doing the same, the system users start complaining that the system performance has slowed down and it’s affecting productivity.
Your current system isn’t scalable as it loses its operational bandwidth when put to use with a greater number of users. Name this as a performance challenge and share it with the IBM i modernization partner.
Now, when you rope in an IBM i modernization partner, consider discussing these insights with them. This will not only help you better your modernization effort but also will give them an objective level road map to follow.
What are my modernization goals in terms of system performance, process optimization, support, etc?
Now that you have understood the significance of gathering first-hand insights, let’s understand the significance of prioritizing them.
IBM i modernization may sound different to each enterprise, depending upon the scope, goals, priority, and urgency. Before you call upon it, it’s of vital importance to figure out the “WHY”.
Let’s do this with a few examples –
Assume that your legacy system is doing quite well since the time you have been using it. With the ever-changing customer needs and demands, you decide to increase your team size.
Initially, you were 500 headstrong and now you are standing at a capacity of 1500. With the increasing team size and the same old legacy system, you have been doing pretty well.
To cope with the rising demand from customers, you keep on increasing the team size. Now you are standing at 1700 and have started seeing delays in processing. You ignore it as you are confident about the system’s capacity.
One fine day, the system crashes and you land in a mess.
What would be your first thought out of regret?
“IBM i modernization could have saved us if we had considered approaching it as we were scaling our team size.”
Correct?
In this scenario, you need to put performance-focused specifications as the top priority when you approach an IBM i modernization partner.
To further it, consider another scenario:
Assume that your legacy system is doing a wonderful job for you for years now.
With the changing business landscape, your marketing and sales team is doing a great job by getting great deals.
With that spike in the requirements, you start seeing a rise in the number of customer complaints about consistent delays in service.
Now whom would you blame this on?
Your service executives or the system itself?
On backtracking the issues observed, you figure out that it’s the system and not manual labor.
It’s a sign that you need to approach IBM i modernization and optimize the processes to scale the throughput.
IBM i modernization is not a job that one can easily pull out in a day or two. You as a part of the system have a major role to play.
You have to know the nitty-gritty of the system that you are using besides the areas that need special attention during the IBM i modernization process.
What security concerns are to be addressed through the IBM i Modernization Process?
Without a second thought, IBM i iSeries is hands down the most reliable, robust, and secure platform. That is one of the reasons that enterprises rely relentlessly on IBM i.
With time, as technology progressed so did the security threats.
As an IBM i user, if you are thinking of IBM i modernization then security enforcement should be your top priority. Security threats like cyberattacks, data leakage, and data breaches can be costlier, not only to your bank account but also to your reputation in the business.
Here are a few scenarios that may help you testify security enforcements that you should consider having during IBM i modernization –
- What is the total number of system users who have access to critical data?
- Is data accessibility being tracked to avoid unwanted data breaches?
- Is there a security provision to combat data attacks?
- How many active user accounts are there? Are these accounts administrated actively?
- Is there a security measure to combat malware vulnerabilities?
These are some ground-level security measures that give you an idea of how your data is being handled and who has access to your data.
Gaining insights into the user and data accessibility, you are now in a position to draft security specifications.
Now, all you need to do is implement these security measures through the right IBM i modernization partner.
What infrastructure, applications, and services need improvement?
IBM i modernization doesn’t mean revamping the whole setup!
A lot of leaders often think of it as an end-to-end revamp and defer IBM i modernization till the system fails. And, to be honest, this costs you 10 times more than the actual modernization.
What we are underlining here is the fact that IBM i modernization is all about an upgrade, to make the system function better. It could be an application, a service, or a hardware component.
All you have to figure out are the challenges and opportunities to improvise. Once you get in talks with an IBM i modernization company, the IBM i experts will determine the components that demand an upgrade.
You get to see a detailed orientation of why a component of your IBM i setup needs a replacement or upgrade and what difference can you expect from it. Nothing goes out of the setup unless and until you agree to do so.
