Module 8
How to break apart monoliths and connect services: strangler fig migration, API gateways, BFF, sidecar pattern, and anti-corruption layers.
Incrementally migrate from monolith to microservices: facade routing, gradual extraction, feature toggle integration, and rollback strategies.
Protect your clean domain model from legacy or external systems: translation layer, facade pattern, and bounded context boundaries.
Dedicated backend services for each frontend client: mobile BFF, web BFF, API composition, and avoiding the one-size-fits-all API problem.
Centralized entry point for microservices: request routing, response aggregation, protocol translation, and cross-cutting concerns.
Use the gateway as a smart router: path-based routing, header-based routing. Offload cross-cutting concerns: auth, rate limiting, SSL termination, compression.
Deploy helper processes alongside your main service: logging, monitoring, proxying, config management. The foundation of service mesh architecture.
A specialized sidecar that handles outbound connectivity: retries, circuit breaking, TLS, and routing on behalf of the main service.
Transform interfaces between incompatible services: protocol adapters, data format converters, and integration with third-party APIs.
