Microservice pattern example implementations for the blog post series: FastAPI Microservice Patterns: Closing the gap to Spring Boot and ASP.NET Core. fastapi-mqtt, gRPC Python implementation)? is a architectural pattern used in software design that promotes . The Monolithic architecture is an alternative to the microservice architecture. From this feature, we created a pseudo-API Gateway pattern that serves as a faade to the independent sub-applications. Microservices - also known as the microservice architecture - is an architectural style that structures an application as a collection of loosely coupled services, which implement business capabilities. The microservices architectural pattern is an architectural style that is growing in popularity, given its flexibility and resilience. Despite the possible drawbacks, the chapter also highlighted domain modeling as an option for organizing components in a FastAPI microservice. It operates independently and isolated from other applications, and is also auto-sufficient in resources. Means a FastAPI service shall expose a REST and MQTT interface to the outside world of the application and shall support gRPC-based communication to "business logic level" microservices. This is a minimalistic and extensible FastAPI template that incorporates factory pattern architecture with divisional folder structure. And it's intended to be the FastAPI of CLIs. Demo of FastAPI + AWS App Runner00:00 Intro00:40 What is FastAPI01:29 AWS App Runner Console01:36 Coding FastAPI in AWS Cloud902:36 Showing Github Actions Jo. 2,021; modified 9 hours ago-2 votes.
