- An AWS Lambda function is a segment of code that operates in reaction to a specific event, effectively transforming applications into sets of independent, smaller services. This serverless compute service, offered by Amazon Web Services, enables users to execute code without the need for server provisioning or management. Lambda functions support various programming languages such as Python, Java, Node.js, and others, with the code deployable directly through the Lambda service or uploaded as a .zip file or container image.
These functions can be activated by a diverse range of events, including API requests, changes in data, file uploads, among others. Lambda functions can be intertwined with other AWS services and respond to changes in those services, as well as API Gateway requests. Specific responses to distinct events can be programmed into the function's configuration.
Lambda functions enable scheduled running at specific intervals, automating regular task execution without human intervention. One of the key advantages of using these functions is that usage charges apply only to the actual compute time used by the code, providing scalability and cost-efficiency. As a result, developers can concentrate on coding and delivering value to the business instead of managing the underlying infrastructure and servers.

- QUOTE: At the time you create a Lambda function, you specify a handler, which is a function in your code, that AWS Lambda can invoke when the service executes your code. Use the following general syntax structure when creating a handler function in Python.

- QUOTE: Each AWS Lambda function runs in its own isolated environment, with its own resources and file system view. AWS Lambda uses the same techniques as Amazon EC2 to provide security and separation at the infrastructure and execution levels.
