Cloud Migration & DevOps Implementation
Complete cloud migration from on-premises infrastructure to AWS, implementing DevOps practices that reduced deployment time by 90% and improved system reliability.
Project Background & Objectives
Mid-Market Technology Company ran mission-critical applications on aging bare-metal servers in a leased data centre with an $380,000 annual co-location bill and a 73-person on-call rotation to manage the resulting fragility. Deployments required a 14-page manual runbook and were executed by a committee — average release cycle was 3 weeks. A single production incident in Q4 2023 caused 19 hours of downtime and ₹2.1 crore in direct revenue loss. Dristi Technologies executed a lift-optimise-and-modernise migration to AWS in 16 weeks, introduced GitOps-based CI/CD pipelines, and handed the team a self-service platform that deploys to production in under 8 minutes.
Most cloud migrations fail to deliver their promised ROI because they lift-and-shift without re-architecture. The real value is in the operational model change — when a developer can ship to production without filing a ticket, velocity compounds and culture transforms.
What Problem Were We Solving?
Mid-Market Technology Company's infrastructure had organically evolved over 11 years into 47 physical servers, 23 manual deployment scripts, and zero automated testing gates. Infrastructure as Code was non-existent — every change was a SSH session and a prayer. The mean time to recovery (MTTR) was 4.2 hours, and the team had experienced 14 unplanned outages in the previous 12 months. Three critical applications had undocumented interdependencies that had never been mapped, making any migration attempt high-risk without extensive discovery work first.
How We Delivered Results
We began with a 3-week Discovery sprint — mapping all 47 servers, 340 network dependencies, and 23 deployment scripts into a single system-of-record. Application tiers were containerised with Docker and migrated to EKS (Kubernetes), with Terraform managing all infrastructure as code. Jenkins pipelines were replaced with GitHub Actions for a developer-native CI/CD experience. Prometheus and Grafana provided real-time observability from day one of cutover. A chaos engineering runbook was delivered alongside the platform, enabling the team to validate resilience proactively.
Mapped all 47 servers, 340 network dependencies, and undocumented application interdependencies using automated tooling before a single migration task began.
Containerised all application tiers with Docker, wrote Terraform modules for every AWS resource, and established a GitOps workflow with environment-specific promotion gates.
Built GitHub Actions pipelines with automated testing gates, deployed Prometheus/Grafana for metrics, Loki for logs, and Jaeger for distributed tracing across all services.
Executed environment-by-environment cutover starting with dev/staging, then production, with a 45-day hypercare period and comprehensive runbook/documentation handover.
Built With Industry-Leading Tools
Every technology was selected for its production readiness, scalability potential, and fit with Mid-Market Technology Company's long-term roadmap.
In Their Own Words
“We'd been talking about moving to the cloud for four years. In four months, Dristi Technologies made it a reality. Our engineers no longer dread releases. We ship five times a week now. That change in developer confidence has been worth every rupee.”
