BetterCloud
BetterCloud’s growth pushed its Mesos/Marathon stack beyond comfortable operational limits at 400M+ events/day. Epsilon delivered a wave-based Kubernetes migration, standardized IaC and GitOps practices, and modernized CI/CD workflows. The result was a more scalable platform, faster delivery, and measurable improvements in cost and performance.
Kubernetes migration
Infrastructure as Code
GitOps implementation
CI/CD modernization
Observability enablement
Rapid growth demanded a platform that could scale reliably beyond 400M events/day while reducing operational friction and improving delivery velocity.
Epsilon executed a wave-based migration to minimize risk while building a repeatable Kubernetes operating model.
Implemented GitHub Actions pipelines for build/test/deploy
Established PR-driven change control for infrastructure and manifests
Created reusable templates and conventions to reduce variance across services
Migrated ~1 microservice/day for ~30 days
Validated each cutover using health, latency, and scaling checks
Documented patterns and trained internal teams to extend the migration
Implemented Prometheus, Grafana, and Alertmanager
Standardized dashboards and alert routing by service/team
Established rollout/rollback runbooks and SLO-style indicators
6 Weeks; Foundation setup + ~30-day service-by-service wave migration
Provisioned clusters via Terraform Defined standards for deploy patterns and environments
Migrated ~1 service/day Established GitOps patterns and observability guardrails
