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.
How it works
AWS Lambda is a serverless, event-driven compute service that lets you run code for virtually any type of application or backend service without provisioning or managing servers. You can trigger Lambda from over 200 AWS services and software as a service (SaaS) applications, and only pay for what you use.
Use Amazon Simple Storage Service (Amazon S3) to trigger AWS Lambda data processing in real time after an upload, or connect to an existing Amazon EFS file system to enable massively parallel shared access for large-scale file processing.

Introduction to AWS Lambda
AWS Lambda is a compute service that runs your code in response to events and automatically manages the compute resources, accelerating your journey from an idea to a modern, production application.
Use cases
Quickly process data at scale
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.
Run interactive web and mobile backends
Combine AWS Lambda with other AWS services to create secure, stable, and scalable online experiences.
Enable powerful ML insights
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.
Create event-driven applications
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.
