In this episode, we will talk about AWS lambda Cold start, and how we can solve the problems. Lambda cold start is a delay that occurs when a new instance of an AWS Lambda function is initialized for the first time. When a Lambda function is invoked, AWS creates a new instance of the function if there is no existing instance available to handle the request. During this process, AWS initializes the function's execution environment, which includes setting up the operating system, loading the necessary libraries and dependencies, and other configuration tasks.
