Hi, Everyone

We have an agile enterprise application built on JSP and Servlet without any design strategy.

This application was built in early 2002 considering 1000 users. After 2002, we received lots of requests from the marketing partners.

Currently, the application has lots of spaghetti code with lots of Ifs and elses. One class has more than 20,000 lines of code with a huge body of functions without abstraction.

Now, we need to support billions of records, what we need to do immediately and gradually?

We have to refactor the application? Which framework, we need to use? How the usage of the framework will be helpful to the end users? How to convince the leaders to do the refactoring? How to gain the faster response time as compare to the current system?
