Migrate Stateful Workloads to StatefulSets with Storage Class Tuning
Overview
What this challenge is about.
Migrate Stateful Workloads to StatefulSets with Storage Class Tuning. Advanced challenge in code. Writing production code that solves real engineering proble...
The Brief
What you'll do, and what you'll demonstrate.
Migrate a Redis Sentinel cluster from bare EC2 to EKS StatefulSets with tuned storage classes and a tested DR story, then produce the playbook for PostgreSQL + Elasticsearch.
This is not a coding exercise. It is the work a software engineer does between a Jira ticket and a merged PR. That distinction matters to every hiring manager who has seen candidates solve LeetCode problems and none who have shipped production code under real constraints.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Design StatefulSets with PVCs, PDBs, and the right storage class
- Tune EBS gp3 IOPS + throughput per workload
- Plan a cutover with snapshot-based data migration
- Define and validate a DR policy end-to-end
