What function does AWS Lambda serve?

AWS Lambda is primarily known for enabling serverless computing, which allows developers to run code without the need to manage the underlying server infrastructure. This means that developers can focus on writing their application code while AWS handles the execution, scaling, and availability of the infrastructure. With Lambda, you can execute code in response to events, such as changes in data within an application or incoming requests, on a pay-as-you-go basis.

This functionality is a key aspect of serverless architectures, where the emphasis is on building applications that automatically scale and only incur costs when resources are consumed. Therefore, using AWS Lambda, you can run applications in a highly efficient manner without the operational overhead associated with provisioning and maintaining servers.

In contrast, long-term storage refers to services like Amazon S3, container orchestration involves services like Amazon ECS or EKS, and safeguarding database transactions typically pertains to database management services that ensure data integrity and security. These functionalities are distinct and do not relate to the core purpose of AWS Lambda as a serverless computing provider.
