Overview
What this challenge is about.
Roll Out mTLS Across 80 Microservices with Istio. Advanced challenge in code. Writing production code that solves real engineering problems, earn a blockchai...
The Brief
What you'll do, and what you'll demonstrate.
Roll out Istio mTLS in PERMISSIVE-then-STRICT mode across 80 microservices with zero downtime and a verifiable per-namespace audit trail.
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 a phased mTLS rollout that survives services with unaware clients
- Configure Istio PeerAuthentication in PERMISSIVE vs STRICT modes correctly
- Use Kiali + Prometheus to observe mTLS coverage per service
- Plan rollback for each phase without breaking ongoing traffic
