Enterprise Case Studies
Real results from real enterprise deployments — with the numbers that matter.
Cloud Native Transformation for a Major Turkish Bank
Migrated 40+ legacy services to Kubernetes with automated CI/CD pipelines — full PCI-DSS compliance maintained throughout.
!The Challenge
The bank operated 40+ legacy Java monoliths on bare-metal servers with quarterly release cycles. Security audits were slow, deployments were risky, and the team lacked confidence in their ability to modernize without disrupting critical banking operations.
✓Our Solution
We designed a cloud-native target architecture using Kubernetes on Azure AKS, built a GitOps-based deployment pipeline with ArgoCD, and executed a phased migration over 9 months — moving services in waves with full rollback capability at every step.
Cloud Cost Optimization for a Leading Telco Group
FinOps assessment revealed 43% cloud waste. Implemented governance framework and rightsizing automation — savings realized in first quarter.
!The Challenge
Cloud spend had grown 300% over three years with no corresponding business growth. Resources were untagged, engineers had no visibility into cost, and leadership had no way to attribute spend to products or teams.
✓Our Solution
We ran a full FinOps maturity assessment, implemented a mandatory tagging policy with automated enforcement, deployed Kubecost for container cost attribution, and identified €2.3M in annual savings through rightsizing, scheduling, and commitment discount optimization.
SRE Practice Built for a Mission-Critical Insurance Platform
Established SLOs, automated incident response, and 24/7 managed operations — reducing P1 incidents by 70% within two months.
!The Challenge
The insurance platform supported 500,000 policyholders and was suffering 3–4 major outages per month. There was no on-call process, no alerting standards, and incidents were handled reactively by developers who had no runbooks to follow.
✓Our Solution
We implemented a full SRE practice in 60 days: defined SLOs for all critical user journeys, built a Prometheus + Grafana observability stack, created incident response runbooks, set up PagerDuty escalation chains, and transitioned to 24/7 managed operations with defined SLA guarantees.
