FastAPI App Deployment Using AWS Lambda And API Gateway

<p><strong>FastAPI&nbsp;</strong>is a modern fast (high-performance)&nbsp;<strong>web framework</strong>&nbsp;for building APIs with&nbsp;<strong>Python</strong>.</p> <h2>FastAPI features</h2> <p><strong>FastAPI</strong>&nbsp;gives you the following, based on open standards</p> <ul> <li><strong>OpenAPI</strong>&nbsp;for API creation, including declarations of path operations, parameters, body requests, security, etc.</li> <li>Automatic data model documentation with&nbsp;<strong>JSON Schema</strong>&nbsp;(as OpenAPI itself is based on JSON Schema).</li> <li>Allows using automatic&nbsp;<strong>client code generation</strong>&nbsp;in many languages.</li> </ul> <p>In this blog we are going to learn how to deploy containerised&nbsp;<strong>FastAPI</strong>&nbsp;Application using&nbsp;<strong>AWS Lambda&nbsp;</strong>and&nbsp;<strong>API Gateway</strong>.</p> <blockquote> <p><strong>FastAPI in Containers -Docker :</strong></p> <p>When deploying FastAPI applications, a common approach it is to build a Linux container image. It&rsquo;s normally done using Docker. Then you can deploy that container image in Lambda . There are several advantages of using Linux containers, including security, replicability, simplicity, and others.</p> </blockquote> <h1>Architecture :</h1> <p>As per below Architecture , end users can able to access the FastAPI api endpoint either using Lambda URL or using API Gateway endpoint.</p> <p><a href="https://blog.searce.com/fastapi-container-app-deployment-using-aws-lambda-and-api-gateway-6721904531d0"><strong>Click Here</strong></a></p>
