Let’s Modernize

As technology changes, more and more businesses are forced to grapple with the need to modernize their legacy applications. There are many approaches to Legacy Application Modernization, including to reuse, rewrite or replace. The goal of reusing the existing application is to gain more value from proven business logic and extend its useful life, while significantly reducing unnecessary operating costs and decreasing risk. All while lowering the risk of inadvertently changing business rules and the higher complexity of code conversion and re-write.

Since there are several modernization approaches, choosing one can be a difficult task. But it’s no surprise that the preference today is migrating to the cloud, as opposed to modernizing with an on-premise, in-house solution. The many benefits of the cloud include faster deployment, lower IT overhead by offloading hardware support requirements, virtually unlimited application scalability, responsiveness for today’s mobile users, and higher utilization and resource efficiency via shared services.

Legacy Application Modernization comes in many layers, you may choose to rehost your application on a cheaper, more accessible cloud solution. You can focus (before or after the rehost) on modernizing your User Interface adding GUI-based Windows screen flow or going all Web based applications. You can focus on your database, choosing modern relational solutions to replace your existing legacy data layer. You could also focus on improving the quality, ease and complexity of your external and internal interfaces. Finally, you can introduce DevOps or DevSecOps into your processes to streamline the development to production pipeline. Astadia can help you with all these options.
