Module 12Principal Masterclass

12. Principal Azure Solutions Architect Best Practices

✓ DO: Use Azure Managed Identities for all service-to-service authentication.

✗ AVOID: Store static database connection strings and client secrets in configuration files.

Engineering Rationale: Managed Identities eliminate credential leaks and automatically rotate access tokens.

✓ DO: Enforce Azure Private Endpoints on all PaaS databases and storage accounts.

✗ AVOID: Expose SQL databases or Key Vaults directly to the public internet.

Engineering Rationale: Private Endpoints route traffic strictly over private VNet IPs, neutralizing public internet attack vectors.

✓ DO: Define high-cardinality partition keys with even access distribution in Cosmos DB.

✗ AVOID: Use low-cardinality keys (e.g. status code) causing hot partition throttling.

Engineering Rationale: Even partition key distribution maximizes throughput and prevents 429 Request Rate Too Large errors.
