The Challenge
RetailOS was running a 12-year-old monolithic Java application that could not scale for Black Friday traffic and took 6 weeks for each release.
The Solution
Apex decomposed the monolith into 23 microservices on Kubernetes, implemented GitOps-based CI/CD, and added auto-scaling with cost-optimised spot instances.
The Results
Release frequency went from 6 weeks to daily. Black Friday handled 4x normal traffic with zero downtime. Infrastructure costs dropped 40%.
