AWS Lambda is an event-driven, serverless computing platform provided by Amazon as a part of Amazon Web Services. It is a computing service that runs code in response to events and automatically manages the computing resources required by that code.

AWS Lambda is a compute service that lets you run code without provisioning or managing servers. Lambda runs your code on a high-availability compute infrastructure and performs all of the administration of the compute resources, including server and operating system maintenance, capacity provisioning and automatic scaling, and logging.

AWS Lambda function helps you to focus on your core product and business logic instead of managing operating system (OS) access control, OS patching, right-sizing, provisioning, scaling, etc. In this AWS Lambda tutorial for beginners, you will learn: How does AWS Lambda work? Events that Trigger AWS Lambda ; AWS Lambda Concepts ; AWS Lambda VS ...

AWS Lambda Getting Started. AWS Lambda is a serverless compute service that runs your code in response to events and automatically manages the underlying compute resources for you, making it easier to build applications that respond quickly to new information.

Provides opinionated guidance on creating, securing, and monitoring AWS Lambda-based applications. Learn about event-driven architectures, application design, debugging, and more.

Carry out the tutorial Using an Amazon S3 trigger to invoke a Lambda function to learn how to configure a Lambda function to be invoked by another AWS service. Choose one of the following tutorials for a more complex example of using Lambda with other AWS services.

AWS Lambda maintains compute capacity across multiple Availability Zones (AZs) in each AWS Region to help protect your code against individual machine or data center facility failures. Both AWS Lambda and the functions running on the service deliver predictable and reliable operational performance.

AWS Lambda participates in Compute Savings Plans, a flexible pricing model that offers low prices on Amazon Elastic Compute Cloud (Amazon EC2), AWS Fargate, and Lambda usage, in exchange for a commitment to a consistent amount of usage (measured in $/hour) for a one- or three-year term.
