Amazon Lambda is a serverless computing platform that allows you to run code in response to specific events or triggers.
A Lambda function is a piece of code that is executed by the Lambda service in response to a trigger.
Here is an example of how you might use a Lambda function:
Imagine that you have a web application that allows users to upload images. When a user uploads an image (an event), you might want to automatically resize the image and create a thumbnail version. To do this, you could create a Lambda function that is triggered by the upload event and performs the image resizing.
The Lambda function might look something like this:
This is just one example of how you might use a Lambda function. You can use Lambda functions to perform a wide variety of tasks, such as processing data streams, automating back-end tasks, and integrating with other AWS services.
