Architecting microservices for fast, sustainable flow

Microservice architecture structures an application as multiple loosely design-time coupled and independently deployable services. This approach facilitates faster deployment pipelines, better observability, and simplifies the evolution of the technology stack. However, it demands careful design to ensure loose coupling and stable APIs, and requires cultural changes in testing and deployment practices. Starting with a monolith may be advisable in new domains to identify stable APIs before transitioning to microservices.
