How does AWS Lambda work?

Last updated on September 25, 2022 @ 5:29 pm

AWS Lambda is a compute cloud service that enables developers to run code in response to events, without having to manage the infrastructure or programming code. Lambda runs on AWS’s virtual servers and uses an event-driven, asynchronous programming model.

You can run code in response to events such as a message being sent over a network, a change in state, or a timer expiring.

AWS Lambda can be used to run code in response to events such as a message being sent over a network, a change in state, or a timer expiring.

Lambda returns an event-driven response, which means that the code doesn’t have to be written in a specific language. You can write code in any language that has an event-driven API.

PRO TIP: AWS Lambda is a serverless computing platform that allows you to run code without provisioning or managing servers. Lambda executes your code only when needed and scales automatically, from a few requests per day to thousands per second. You pay only for the compute time you consume – there is no charge when your code is not running.

Lambda also uses an asynchronous programming model, which allows the code to run asynchronously and return immediately. This allows you to run multiple threads of code in parallel, which can speed up the execution of your code.

Lambda also has a low-cost architecture, which means that you can run a large number of instances without incurring large costs.

Overall, AWS Lambda is a compute cloud service that enables developers to run code in response to events, without having to manage the infrastructure or programming code.

This allows you to write code in any language that has an event-driven API, and the code can run asynchronously and return immediately. Lambda also has a low-cost architecture, which means that you can run a large number of instances without incurring large costs.
