Migrating and Modernizing Future and Options Trading Web Application for Investors on Google Cloud

Client

The client is a major British universal banking and financial services company. It has historical and business links to East Asia and a multinational footprint.

Challenges

The client wanted to migrate applications to Google Cloud Platform (GCP) to harness on-demand scalability benefits. Issues with application performance, such as slow initial page loading and delayed responses, negatively impacted user experience. Manual testing and deployment procedures extended the cycle time between requirements and releases. The aim was to optimize costs by leveraging efficient cloud computing resources and managed services on GCP. The company also wanted to reduce licensing costs for the database and web server.
