AWS Lambda

Run code without thinking about servers or clusters

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.

File Processing

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.

Stream Processing

Use AWS Lambda and Amazon Kinesis to process real-time streaming data for application activity tracking, transaction order processing, clickstream analysis, data cleansing, log filtering, indexing, social media analysis, IoT device data telemetry, and metering.

Web Applications

Combine AWS Lambda with other AWS services to build powerful web applications that automatically scale up and down and run in a highly available configuration across multiple data centers.

IoT Backends 

Build serverless backends using AWS Lambda to handle web, mobile, Internet of Things (IoT), and third-party API requests.

Use cases

Process data at scale

Execute code at the capacity you need, as you need it. Scale to match your data volume automatically and enable custom 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.
