A CASE STUDY ON APPLICATION MIGRATION WITH A MICROSERVICES ARCHITECTURE

A leader in financial printing and communication solutions with more than 50 years of industry experience wanted to migrate their application to advanced Java with a microservices architecture to better handle scalability, speed, application security, and quality assurance.

Problem Statement

Our client has been a pioneer and trusted partner to the financial, legal, and corporate communities for five decades, providing secure, innovative solutions to complex content and communications requirements.

The client’s original application was built on a huge monolith architecture written on an Oracle platform with Oracle Forms 2000 and back-end comprising several batch processes written in Java Struts, which handled everything from user registration to login to editing and servicing content.

Being tied to a single monolithic architecture, the client faced the following challenges

  • Scaling the application on top of the existing code base was difficult
  • Building additional features increased complexity, slowed down development, introduces bugs, and makes testing cumbersome
  • Slower time to market for newer product & services
  • And downtime of the application was way too long

To overcome these challenges, the client wanted to upgrade their decade-old system applications to the latest Java code with a microservices architecture to meet new business models and customer expectations and was on the lookout for a digital transformation partner for end-to-end migration and support.

BUSINESS GOALS

Migrate old core Java application to latest Spring Java without affecting UI/UX

Browser compatibility, glitch-free development process, and enhanced security

Higher scalability with API's and improved quality assurance

Faster time to market for each incremental release

Uninterrupted delivery of product and services

Zuci Systems initiated this project by evaluating the client’s existing IT infrastructure to define the success metrics, which helped the project team and client to understand the business goals before starting the project.

With this information, Zuci quickly viewed the underlying business rules and processes running their system, making it easy to identify and modernize the application to event-driven, highly scalable microservices-based architecture within three months.

Converted the 50000 Java lines to only a 10000 lines advanced JAVA program, which is more readable and even easier to understand

Used CI/CD pipeline for faster release by automating the execution of unit and system, and integration of test cases

Our team also incorporated a rich responsive user interface and along with cross-browser support

Lastly, deployed complete end-to-end migration to the microservices architecture, followed by ongoing support to stakeholders with workshops and Q&A sessions
