With Lambda, all you need to do is supply your code in one of the language runtimes that Lambda supports. You organize your code into Lambda functions. The Lambda service runs your function only when needed and scales automatically. You only pay for the compute time that you consume—there is no charge when your code is not running.
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.
Choose your own path. 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.
AWS Lambda is an event-driven, serverless Function as a Service (FaaS) provided by Amazon as a part of Amazon Web Services. It is designed to enable developers to run code without provisioning or managing servers.
Using Lambda with API Gateway: Create an Amazon API Gateway REST API that invokes a Lambda function. Using a Lambda function to access an Amazon RDS database : Use a Lambda function to write data to an Amazon Relational Database Service (Amazon RDS) database through RDS Proxy.
With AWS Lambda, you can run code without provisioning or managing servers. You pay only for the compute time that you consume—there's no charge when your code isn't running. You can run code for virtually any type of application or backend service—all with zero administration.
AWS Lambda allows you to add custom logic to AWS resources such as Amazon S3 buckets and Amazon DynamoDB tables, so you can easily apply compute to data as it enters or moves through the cloud. It is easy to get started with AWS Lambda.
We will walk through how to create a Hello World Lambda function using the AWS Lambda console. We will then show you how to manually invoke the Lambda function using sample event data and review your output metrics. Everything done in this tutorial is Free Tier eligible.
AWS Lambda functions running on Graviton2, using an Arm-based processor architecture designed by AWS, deliver up to 34% better price performance compared to functions running on x86 processors. This applies to a variety of serverless workloads, such as web and mobile backends, data, and media processing.
