Cost and technical judgment
Platform Cost And Migration Decisions
Storage and compute migration work that balanced modernization, reliability, and ROI instead of migrating for its own sake.
Professional case study
10+ clusters evaluated
1,000+ workloads considered
Negative-ROI migration avoided
Problem
Platform migrations and managed compute options needed cost, risk, and reliability validation before being rolled into production paths.
Action
Automated gp2-to-gp3 migration steps, validated Karpenter behavior, and evaluated EKS Auto Mode feasibility across 10+ clusters and 1,000+ workloads.
Outcome
Completed safer storage modernization work and recommended holding off on a negative-ROI compute migration path that would have created high operational toil.
engineering takeaways
Reusable patterns from the work.
These notes focus on the engineering judgment, tradeoffs, and patterns behind the work.
- Treated no-go recommendations as valid engineering outcomes when the data did not support moving to EKS Auto Mode from existing self-managed Karpenter setup.
- Balanced platform stability, manual migration effort, and cost premium.
- Applied migration automation where the tradeoff was clear and beneficial.
