Overview
What this challenge is about.
Migrate a multi-cluster platform from Linkerd to Istio using Helm and Argo Rollouts. Validate latency parity and earn a verifiable certificate.
The scenario
The SaaS (sells observability to engineering teams, eats its own dogfood) needs Istio's AuthorizationPolicy to ship per-tenant network isolation — a top customer demand from the Enterprise tier.
The Brief
What you'll do, and what you'll demonstrate.
Migrate from Linkerd to Istio across 7 clusters and 24 namespaces with no latency regression and zero customer-visible downtime.
Earning criteria — what you'll demonstrate
- Plan a service-mesh migration with both meshes coexisting safely
- Compare Linkerd's micro-proxy model to Istio's Envoy-based data plane
- Automate per-namespace cutover with Helm + progressive delivery
- Validate mesh-migration latency parity at p99 across multiple clusters
