AWS Lambda Web Adapter: Run Your Web Applications on Serverless
The AWS Lambda Web Adapter is a tool that enables you to run web applications built with common frameworks on AWS Lambda with minimal code changes, converting Lambda events into HTTP requests and vice versa.

LanguageProject Introduction
Summary
The AWS Lambda Web Adapter is an open-source project from AWS Labs that acts as a proxy, allowing popular web application frameworks and their code to run on AWS Lambda functions by bridging the gap between Lambda's event model and the HTTP request/response model expected by web servers.
Problem Solved
Traditional web applications and frameworks are designed to run on long-running servers and handle standard HTTP traffic. Adapting them to the AWS Lambda event-driven model typically requires significant code changes or wrapper layers. The Web Adapter solves this by providing a compatibility layer.
Core Features
Event-to-HTTP Translation
Translates AWS Lambda invocation events into standard HTTP requests that your web framework can understand.
Framework Compatibility
Allows existing web frameworks like Spring Boot, Express, Django, Ruby on Rails, and others to run on Lambda without extensive refactoring.
Performance Optimization
Optimized for performance and cold starts, providing an efficient way to run web apps serverlessly.
Tech Stack
Go (for the adapter itself)
Any language supported by Lambda
Any web framework (Spring Boot, Express, Django, Ruby on Rails, etc.)
Use Cases
The adapter is suitable for various scenarios where you want to benefit from AWS Lambda's serverless model while using established web frameworks.
Migrating Existing Web Applications
Details
Migrate a monolithic application built with Spring Boot or Django to AWS Lambda, breaking it down into potentially smaller, serverless components.
User Value
Reduces infrastructure management, scales automatically, and potentially lowers costs.
Developing New Serverless Microservices
Details
Develop new microservices or APIs using familiar frameworks like Express.js or Flask, deploying them efficiently as Lambda functions.
User Value
Leverages developer familiarity with frameworks while adopting a serverless operational model.
Running Framework Sub-components on Lambda
Details
Run specific endpoints or functionalities of a larger web application as independent Lambda functions.
User Value
Enables gradual adoption of serverless for parts of an application, improving scalability and isolation.
