The Challenge
A large enterprise client was running critical workloads across aging on-premise datacenters. Deployments were manual and error-prone, taking days to coordinate across teams. Infrastructure changes required filing tickets and waiting for operations staff to execute them. The lack of reproducibility meant that staging and production environments drifted apart, leading to frequent “works on my machine” failures during releases.
The client needed to migrate to a cloud-native architecture without disrupting ongoing operations, while simultaneously improving deployment velocity and infrastructure reliability.
What We Delivered
-
Containerization Strategy — Assessed the existing application portfolio and developed a phased containerization plan. Applications were categorized by migration complexity, and we started with stateless services before tackling stateful workloads.
-
Kubernetes Platform — Designed and deployed production Kubernetes clusters with proper namespace isolation, resource quotas, and RBAC policies. The platform was built to support multiple teams deploying independently without stepping on each other.
-
Infrastructure as Code — Implemented Terraform for provisioning cloud resources, ensuring that every piece of infrastructure is defined in version-controlled code. No more manual changes through cloud consoles.
-
GitOps Deployment Pipeline — Deployed Flux and ArgoCD to establish a GitOps workflow where every change — from application updates to infrastructure modifications — flows through Git pull requests, with automated reconciliation to the cluster state.
-
CI/CD Integration — Built continuous integration pipelines that produce container images, run tests, and update deployment manifests automatically. Developers push code; the pipeline handles the rest.
-
Observability Stack — Set up monitoring, logging, and alerting using Prometheus, Grafana, and centralized log aggregation, giving teams visibility into application and infrastructure health.
The Outcome
The migration transformed how the organization delivers software:
- Deployment time reduced from days to minutes through automated GitOps pipelines
- Environment parity between development, staging, and production, eliminating drift-related failures
- Self-service infrastructure enabling development teams to provision what they need without waiting for operations
- Full audit trail of every infrastructure and application change through Git history
- Improved resilience with Kubernetes handling automatic restarts, scaling, and rolling updates
