DevOps engineering: resolving technical debt on a Kubernetes cluster
An orchestration platform unblocked after being paralyzed by organizational deadlocks. Testing automated and deployment agility restored.
01 Challenges and context
Context and strategic stakes
A major European banking group faced a significant technological impasse: a modern container orchestration infrastructure (On-Premise Kubernetes) had been deployed at great expense but remained completely inactive and unable to support any production workload for eighteen months. The issue was not technological but organizational: unshared Continuous Integration/Continuous Delivery (CI/CD) pipelines, a Kafkaesque entanglement of manual validations preventing agility, a complete breakdown in dialogue with Application Owners, and a frozen Time-to-Market. The mission was to break these barriers to justify the initial investment.
02 Work carried out
Approach and methodology
We conducted a thorough analysis of the software delivery chain. This analysis exposed a profound lack of trust between Development and Operations teams, compensated by an accumulation of nonsensical manual validation gates. We mapped the critical path of an application deployment and quantified the days lost in bureaucratic validation loops.
03 Outcomes achieved
Results and indicators
18 months
Platform inactive for
3 months
Time to production
45 %
Reduction in manual validations
Rapid Unblocking: The Kubernetes platform, stagnant for 18 months, was made 100% operational for production in just 3 months of intervention.
Technical Fluidity: Eradication of 45% of human validation actions on the critical code path.
Commercial Success: Successful production launch of the first wave of critical applications, finally validating the profitability of the infrastructure.
