AWS Lambda SnapStart is designed to specifically enhance cold start latency for Lambda functions. Cold starts occur when a Lambda function is invoked for the first time or after a period of inactivity, leading to noticeable delays in execution as the environment is initialized. SnapStart addresses this challenge by optimizing the startup time of Java-based Lambda functions.

With SnapStart, AWS captures a snapshot of the execution environment for a Lambda function and stores it. When the function is invoked, it can start from this snapshot instead of having to fully initialize a new execution environment from scratch. This significantly reduces the time it takes for the function to be ready to run, thereby improving the response time experienced by end-users.

While the other options address important aspects of performance or security in cloud environments, they are not the focus of AWS Lambda SnapStart. The primary goal of this feature is to minimize the cold start latency, making it particularly beneficial for applications that require quick responsiveness.
