The microservices architectural pattern is an architectural style that is growing in popularity, given its flexibility and resilience. Arthur Hv. Once running, a microservice can be used via API calls on its exposed endpoints. RedisJSON is a NoSQL database just like MongoDB and Redis Streams is an Event Bus just like RabbitMQ or Apache Kafka. During development and maintenance of microservices things go. Containerize FastAPI and Streamlit with Docker. This architecture enables smaller teams to support smaller parts of the application and clearly defines contracts between the different parts of an application. The frontend is used to acquire information from the user on characteristics that are used as input for the predictive model. fastapi-microservice-patterns. The first transaction in a saga is initiated by an external request corresponding to the system operation, and then each subsequent step is triggered by the completion of the previous one. The following are 30 code examples of fastapi.FastAPI(). Typer, the FastAPI of CLIs If you are building a CLI app to be used in the terminal instead of a web API, check out Typer. Typer is FastAPI's little sibling. After that, this book will guide you on how to apply and translate microservices design patterns in building various microservices applications and RESTful APIs using the FastAPI framework. External versus internal architecture and design patterns. It also enables an organization to evolve its technology stack. Pydantic for the data parts . Saga pattern is the solution to implementing business transactions spanning multiple microservices. A Saga is basically a sequence of local transactions. This is a minimalistic and extensible FastAPI template that incorporates factory pattern architecture with divisional folder structure. 2. By the end of this microservices book, you'll be able to understand, build, deploy, test, and experiment with microservices and their components using the . python api-design hexagonal-architecture .
