Design Multi-Tenant Network Policies with Calico Tier Enforcement
Overview
What this challenge is about.
Design Calico tier policies for a multi-tenant B2B SaaS platform, build a test harness, and deliver a rollout runbook to earn your verifiable certificate.
The scenario
The SaaS (regulated under SOC 2 + ISO 27001 + GDPR, with EU customers) cannot ship the next quarter's customer commitments without proven cross-tenant isolation.
The Brief
What you'll do, and what you'll demonstrate.
Design and roll out tiered Calico network policies enforcing default-deny with per-tenant allowlists across 120 customer namespaces and validate isolation with a 120x124 test matrix.
Earning criteria — what you'll demonstrate
- Design tiered network policies that scale across many tenants
- Use Calico stage policies to avoid breaking-change rollouts
- Validate isolation with an end-to-end test matrix
- Document policies cleanly enough that tenant onboarding stays cheap
