Microservice Architecture
Independent, deployable services aligned to business domains, communicating via APIs, events, or streams.
Architecture Diagram
Enabled By Platform Building Blocks
- Messaging & Streaming Platform: Provides secure, observable messaging and streaming infrastructure to enable event-driven patterns, decouple services, support async workflows, and ensure enterprise-grade reliability.
- API Management: Securely exposes APIs, enforces policies, manages discoverability, and enables AI agent integration.
- Internal Developer Platform: Enables self-service deployments, golden paths, and faster delivery cycles.
- Observability & Operations: Provides visibility, SLOs, and resilience validation across architectures.
What it is
A distributed style decomposing systems into small services owned by autonomous teams, enabling independent releases and scaling.
Responsibilities
- Each service owns its data and contracts
- Resilience patterns: retries, timeouts, circuit breakers
- Observability and platform guardrails
Patterns
- Domain-driven boundaries
- Saga and outbox for consistency
- BFF for tailored client APIs
- Service mesh for zero trust
Trade-offs
- Operational complexity and higher cognitive load
- Distributed systems failure modes
- Testing and data consistency become harder
When to use
- Complex, evolving domains with many teams
- Need for independent scaling and releases
- Strong platform engineering in place
