Asynchronous Lambda Invocations

Welcome! In serverless, functions can be invoked in different ways. An asynchronous invocation means the caller doesn't wait for the function to finish executing.

Think of it like sending a letter: you drop it in the mailbox, and you don't wait for the recipient to read it. You trust it will be delivered and processed later.

When you invoke a Lambda function synchronously, you wait for a response immediately. Your application pauses until Lambda returns a result or an error.

With asynchronous invocation, Lambda places the event in an internal queue and immediately returns a success message to the caller. The actual function execution happens in the background.
