Client Success

Global fintech leader leverages AWS Cloud to modernize enterprise applications to boost operations and innovation 

The client is a US-based global leader in the fintech domain, providing financial, accounting, and tax preparation solutions to over 100 million customers across nine countries.

The Challenge

The client faced several operational issues with the existing legacy enterprise applications deployed on unsupported operating systems and on traditional hosted data center infrastructure. This slowed innovation and led to scalability issues which negatively impacted product engineering teams. To delight engineering teams by improving performance, scalability, user experience and delivery process, they wanted to migrate 70+ enterprise applications and related data from the core financials, people and places and privacy engineering groups to the AWS Cloud. Security quickly became a primary consideration throughout the journey as much of the data that once resided on prem was moved to the cloud.

The Solution

As the client’s digital transformation partner, Persistent adopted a multi[1]phase modernization approach.

 In the first phase, Persistent did an in-depth code analysis to understand all applications’ operational aspects. It included re-factoring existing applications to make them cloud[1]ready while adhering to the corporate standards for security and compliance.

In the second phase, Persistent helped in migrating the cloud-ready applications to the AWS platform and deployed several AWS components, including CodePipeline and CodeBuild. It was vital to run performance testing, chaos testing and CI/CD pipeline integration as per corporate policies. The team Persistent applied production cutover to migrate all the applications from the test environment to the production environment.

 In the third phase, the focus was on the containerization of applications. It was essential to modernizing the client’s existing enterprise legacy applications with cloud-native deployments.

Persistent also ran Amazon CloudWatch to help the client monitor AWS resources and applications in the cloud and on the server. It built an enterprise intelligence platform to enable data analytics for the client.

Following DevSecOps principles, Persistent also ensured end-to-end automation of infrastructure provisioning, continuous integration and deployment.

The Outcome

Speed to innovation is critical for any fintech. This client saw many benefits from the cloud migration and modernization of enterprise systems, including enhanced operational capabilities and increased stakeholder delight. With 70+ legacy applications being moved to the AWS cloud, the client can now scale rapidly, improve performance and enhance stability — all while maintaining security and compliance. As it led to the decommissioning of its on-premises data centers, the client has been able to reduce costs.
