War Stories About the Ops in DevOps
summary
Web product runs up to 200 services, millions of API requests per day, with ~20 developers and ~5 ops; infrastructure is push-button server restart and automated failover so patching, scaling and Redis provisioning happen without developer coordination. Deploys go through version-controlled infra and test suites — sometimes 200 deploys a day — with scripted framework bumps and rolling rollbacks. Database migrations use dual-read/write formats for zero-downtime swaps. Operations sit with developers and third-party experts, delivering ops-as-a-service and ~99.99% uptime.
