Mainframe Modernization for Banks: PowerBuilder to Java Conversion with Assured ROI
PowerBuilder to Java conversion creates access to many new technologies and enables easy integration of a new products and service into the banking system. Bank CTOs need not go through the time, effort, and expense required to build something from scratch. Let us therefore investigate more about some of the other top reasons that are compelling CTOs to look at the benefits of migration from PowerBuilder to Java.
Typically, legacy apps that are built in the PowerBuilder pose multiple challenges for banking sector innovators. While the need of the hour is to find a cost-effective way for launching new services, PowerBuilder Apps fall short due to their 32-bit performance issues. Moreover, they are built for the desktop era and bring up multiple limitations if one aspires to modernize the product or service experience. Developers dread the very thought of having to go an unknown legacy platform to introduce any change as it then also implies testing millions of lines of codes over and over again.

No more getting tied down to a system built for desktop environments
While back in the days, the PowerBuilder was a great tool to design and deploy desktop applications, there are multiple scenarios that today require apps to work on mobile devices as well. Migrating business critical apps can help users greatly benefit from new web technologies. It would greatly enhance the way users interact with the applications from any device that renders HTML. This way the Bank’s CTO team can be assured that customers don’t switch to a rival who is able to innovate at a faster pace.
Take full advantage of new-age technologies, products, and services
By migrating from PowerBuilder to Java the improvements you can unlock new features made possible by the consumption of RESTful APIs. These APIs can enable new, game-changing experiences. These API integrations are not easy to bring in if the apps are made in PowerBuilder and it requires niche specialization as well as skills. With a migration to Java, connecting to other banks and financial institutions becomes easier. For example, the bank can use APIs to access and regulate the sharing of information related to customers as a moment’s time and in almost real-time speed which changes the experience for many transactions, customer requests, and processes.
Speed-up innovation with easy integration of SaaS finance products
If a bank wants to add a product or service as a new offering for customers, they need not go through the time, effort, and expenses required to build something from scratch. With the use of plug-and-play APIs, banks can now bring use the modularity offered by different FinTech companies and SaaS products to integrate them and help them communicate with the in-house system. By upgrading from PowerBuilder to Java, developers can now just lift and shift and integrate new features from a pick-and-choose menu of options available in the market. The use of automated testing for new APIs made possible by the Java migration can further speed-up the delivery with Continous Integration and Continous Delivery (CI/CD).
Most of our clients have reached out to us for modernizing their PowerBuilder applications due to lack of resources in-house. Most of their experienced employees have already retired or are on the verge of retiring. At the same time, it has also become extremely hard to find new people with adequate levels of skills and hand’s-on experience required for development and maintenance of business-critical apps. Migration to Java opens the possibility of increasing the team size of developers whereby the team can leverage the availability of cheaper resources and entry-level developers for Java. Moving to Java completely rids them of these problems with our experts who are not just well versed in Java but also know how to do a line-by-line refactoring of apps originally written in a COBOL or a PowerBuilder.
Create Dynamic websites by overcoming limitations in PowerBuilder
Any website, feature and/or an interface can be termed as dynamic when it changes content or the layout without any any new page request to the web browser. These dynamic or interactive experiences are nothing but web pages that produce a different content for each user using the same source code file. The content is assembled from multiple sources to be simply updated on the website. For example, the home page of your social media networking login or the ecommerce store that shows a different content for each user based on their browsing preferences and choices. Not only do Dynamic Websites require web hosting but would also need databases and servers. This is precisely APIs become handy and this calls for a conversion of PowerBuilder to make development more cost effective and easy.
Accelerate the development of more functional and interactive features
Enable greater degree of automation in IT Infrastructure management
When developers try to replicate UI controls from PowerBuilder to Java, they are likely to come across some key challenges. These would include mapping DataWindow controls, edit masks, and reports with each other. Knowledge of replicating the mapping in Java requires specialized skills and hand’s-on project experience, something that is not possible for developers who know only PowerBuilder. Many of the events created in PowerBuilder UI would not have any equivalent in Java Swing. Hence, Developers who have faced these scenarios along with reusable codes are required for a smooth migration. It is always recommended to ask your vendor to present a quick snapshot of such challenges and the reusable code-repositories that can be used for them.
