The article discusses microservices architecture, its core principles, and implementation patterns. Microservices architecture is built on principles such as service independence, technology diversity, independent deployment, fault isolation, and data autonomy. However, it also introduces complexities like distributed system complexity, operational overhead, data management, and testing complexity. The article provides an example of a basic microservice setup using the Hyperlane framework. It also discusses service communication patterns, including HTTP/REST and gRPC communication. The article covers service discovery and load balancing, including a service registry implementation and a load balancer implementation. Additionally, it discusses the circuit breaker pattern, which prevents cascading failures in a microservices system. The article also covers database patterns for microservices, including the database per service pattern and the saga pattern for distributed transactions. Finally, it touches on monitoring and observability, including distributed tracing and metrics collection.
