AWS Lambda

AWS Lambda is a serverless compute service offered by Amazon Web Services (AWS), the cloud computing arm of Amazon.com, Inc. Launched in 2014, Lambda lets developers run code in response to events — such as HTTP requests, file uploads to Amazon S3, database changes, or messages on a queue — without provisioning or managing servers. Customers upload their function code, choose a runtime and memory allocation, and AWS handles scaling, patching, and availability automatically, billing only for compute time consumed. Lambda sits at the center of AWS's serverless portfolio. It integrates with a wide range of AWS services including API Gateway, S3, DynamoDB, SQS, SNS, EventBridge, and Step Functions, and supports multiple programming languages such as Node.js, Python, Java, Go, .NET, and Ruby, along with container-image-based deployment. Because it abstracts away infrastructure, Lambda is widely used for web backends, data processing pipelines, automation, and event-driven microservices. As a product brand, Lambda is positioned as the reference implementation of Function-as-a-Service (FaaS) and helped popularize the serverless computing category across the cloud industry. It competes with rival offerings such as Microsoft Azure Functions and Google Cloud Functions. Lambda is not a separately listed company; it is a branded service within AWS, which is reported as a segment of Amazon.com, Inc. (NASDAQ: AMZN). Its pricing, features, and regional availability are managed by AWS and evolve continuously through re:Invent announcements and service updates.

AWS Lambda was introduced by Amazon Web Services in 2014 as one of the first mainstream Function-as-a-Service offerings, allowing developers to run code without managing servers. It grew out of AWS's broader push to abstract infrastructure and let customers pay only for consumed compute time. Over the following years Lambda expanded its supported runtimes, memory configurations, and integration points across the AWS ecosystem, becoming a foundational building block for event-driven architectures. AWS added capabilities such as Lambda@Edge for customizing content at edge locations, provisioned concurrency for latency-sensitive workloads, and support for deploying functions as container images. Lambda became closely associated with the serverless movement, and AWS uses its annual re:Invent conference to announce new Lambda features and pricing options. The service remains a flagship part of AWS's compute portfolio alongside Amazon EC2, ECS, and Fargate, and it is a common reference point when the industry discusses serverless computing.
