Why Lambda?

AWS Lambda is a compute service that runs your code in response to events and automatically manages the compute resources, making it the fastest way to turn an idea into a modern, production, serverless applications.

Benefits of Lambda

Run code without provisioning or managing infrastructure. Simply write and upload code as a .zip file or container image.
Automatically respond to code execution requests at any scale, from a dozen events per day to hundreds of thousands per second.
Save costs by paying only for the compute time you use—by the millisecond—instead of provisioning infrastructure upfront for peak capacity.
Optimize code execution time and performance with the right function memory size. Respond to high demand in double-digit milliseconds with Provisioned Concurrency.

AWS for every application

AWS Lambda, a serverless compute service, executes your code in response to events, handling compute resources for you. Discover how AWS's comprehensive set of infrastructure capabilities and services enables rapid and cost-effective modern applications development.

Use cases

Meet resource-intensive and unpredictable demand by using AWS Lambda to instantly scale out to more than 18k vCPUs. Build processing workflows quickly and easily with suite of other serverless offerings and event triggers.
Combine AWS Lambda with other AWS services to create secure, stable, and scalable online experiences.
Preprocess data before feeding it to your machine learning (ML) model. With Amazon Elastic File System (EFS) access, AWS Lambda handles infrastructure management and provisioning to simplify scaling.
Build event-driven functions for easy communication between decoupled services. Reduce costs by running applications during times of peak demand without crashing or over-provisioning resources.
