The Imperative for Change
Although the large UK bank had migrated its ERM workloads to AWS, the setup was fragmented, heavily manual, and lacked compliance with critical non-functional requirements such as disaster recovery, security, and scalability. The existing platform was at end of life and was 13 versions behind leading to a huge compliance risk for the bank. The planned upgrade is an enabler for the bank to meet repeatable deployments and enable faster upgrades. Publicis Sapient was brought in to transform the deployment into a fully automated, modular, and enterprise-compliant solution—leveraging Terraform, PowerShell, GitLab CI/CD, and AWS-native services to create a scalable and secure environment aligned with modern DevOps and infrastructure best practices.
