Global Investment Bank Improves Efficiency with Microservices UI and Cloud Transformation

Capital Markets


Supported by legacy technologies, a global investment bank’s front-office application was at a crossroads and needed to be upgraded. The bank looked for a technology partner to help them migrate to the cloud.


We helped the bank create a cloud migration strategy, which will set a new architectural and operational standard once fully implemented.

A top-tier global investment bank’s front-office application was at a crossroads—with legacy technologies supporting their systems, they needed an upgrade that would allow them to streamline operations and increase reliability and efficiency.


Migrating to the cloud would help improve scalability, reduce process complexity, and define the gold standard for a new era of operations. To kick off their technology transformation, the bank leveraged Endava’s expertise in cloud operations to upgrade their application framework and enhance functionality. 

Driving Partners Toward Big-Picture Goals

As technologies advanced, so did industry standards, making digital transformation a top priority for the bank. As part of upgrading their application, the bank also needed to build new security protocols, create new architecture, and ensure continuous integration. 


The bank's main challenges included:

  • Navigating complex legacy systems
  • Securing internal resources to support their transformation
  • Finding deep technical expertise in cloud operations
  • Scaling new architecture across the organization

Our team is not only helping establish agile methodologies but spearheading an effort to move to the cloud in a complex enterprise environment.Tom CohenDelivery Partner, Capital Markets

Creating the Gold Standard

This project was the first of its kind at the bank, which allowed Endava to partner closely with internal teams to define the gold standard. In addition to creating a strategy to migrate the bank’s main application to the cloud, Endava also built a greenfield application that archives data daily and creates more accurate and consistent reporting. 


Endava assembled two teams of development experts:


1. Angular
This team focused on upgrading the bank's UI and ensuring compliance with security demands.

2. Java

This team focused on microservices and cloud functionality, as well as a data archival process to help with automating and streamlining existing operations. 

Paving the Way for Modernization

Endava worked with the bank to create the cloud migration strategy, which will set a new architectural and operational standard once fully implemented. As Endava continues to partner with the bank on this initiative, their modernization efforts continue to improve efficiency, reliability, and scalability. 


Overall, the digital transformation will help the bank:

  • Steadily migrate infrastructure and code to the cloud
  • Create a more reliable and resilient platform
  • Establish a testing automation backbone to reduce manual effort
  • Develop code quality standards to reduce vulnerabilities
  • Deploy features and resolve issues faster
