Multi-Service Release Example

Last updated on

This example demonstrates how to orchestrate a release involving multiple services with dependencies.

Scenario​

Release three services:

  • Service A: Core service
  • Service B: Depends on Service A
  • Service C: Depends on Service A and B

Process Design​

Phase 1: Preparation​

  • Code freeze
  • Branch creation
  • Dependency validation

Phase 2: Build​

Build all services in parallel:

  • Build Service A
  • Build Service B
  • Build Service C

Phase 3: Integration Testing​

  • Deploy to integration environment
  • Run integration tests
  • Validate dependencies

Phase 4: Staging​

  • Deploy to staging
  • User acceptance testing
  • Approval required

Phase 5: Production​

  • Production approval
  • Deploy Service A
  • Deploy Service B (after A)
  • Deploy Service C (after A and B)
  • Post-deployment validation

Key Features​

Dependency Management​

  • Service B depends on Service A
  • Service C depends on Service A and B
  • Sequential deployment in production

Parallel Execution​

  • Build phase: Parallel builds
  • Testing: Parallel where possible
  • Production: Sequential deployment
