By :

AWS Lambda is a serverless, event-driven computing service that lets you run code for virtually any application or backend service (that’s Linux-compatible). Under the covers, it uses a purpose-built operating system called Firecracker to scale your code elastically within milliseconds. This capability allows Lambda to support burst traffic patterns and AWS to charge per millisecond that your code is running!
There are three phases to a Lambda function’s life cycle: Init
, Invoke
, and Shutdown
. During the Init
phase, your code should fetch configuration information and prepare any stateless clients. Next, the Lambda service will invoke the lambda_handler
entry point one or more times. After processing all pending events, the service eventually releases the underlying Firecracker micro-virtual machine.
