Case Study of Success
summary
A large retail bank migrated 62% of workloads to the cloud using AWS, CloudFormation and OpenShift and treats DevOps as a product to scale to 10,000+ Git repositories with 27,000 CI runs per week and 11,658 production deployments year-to-date. The organization achieved 30-minute application cycle times and multiple daily deploys by automating CI/CD with tools like Git, SonarQube, Prisma Cloud, Selenium and Liquibase, and shifted security from quarterly scans to continuous static, dynamic and SCA testing with policy gates, resulting in ~34,000 non‑prod bugs remediated and an 89% remediation rate.
