“How can you modernize a live retail platform without causing downtime and interrupting sales?”
For our client, this was a complete infrastructure transformation executed on a live, revenue-generating platform. Our approach was designed to systematically modernize every layer of their technology stack from containerization and CI/CD automation to security hardening and real-time observability.
- Migrating to a Kubernetes-Based Architecture. The foundation of the modernization was the migration from standalone EC2 instances to a fully containerized environment orchestrated by Kubernetes. We implemented dynamic development environments, allowing developers to spin up isolated testing spaces on demand, dramatically accelerating their development cycles and reducing conflicts between teams.
- Optimizing CI/CD for Zero-Downtime Deployments. We rebuilt the entire deployment pipeline, migrating to self-hosted CircleCI runners to reduce costs and implementing the Gitflow methodology for structured code management. The new pipeline included automated testing, zero-downtime deployment strategies, and real-time Slack notifications, enabling the team to ship features faster and with complete confidence.
- Implementing Enterprise-Grade Security & Compliance. Security was hardened across the entire stack. We deployed a WAF to protect against external threats, implemented end-to-end encryption for all data, migrated databases to managed services for high availability, and restricted access to staging environments via VPN, ensuring that only authorized personnel could reach sensitive infrastructure.
- Establishing 24/7 Observability & Support. To ensure operational excellence, we deployed a comprehensive monitoring stack using Grafana and Prometheus for real-time infrastructure and application health metrics, and the ELK stack for centralized logging. Our 24/7 on-call support team ensures that any critical issues are detected and resolved proactively, maintaining the high availability that their customers depend on.
