https://aws.amazon.com/polly/ Our customers tell me that they love https://aws.amazon.com/lambda/ for many reasons. On the development side they appreciate the simple programming model and ease with which their functions can make use of other AWS services.
The https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtime-environment.html#runtimes-lifecycle of each environment consists of three main phases: Init, Invoke, and Shutdown. Among other things, the Init phase bootstraps the https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtimes.html for the function and runs the function’s static code.
After you enable Lambda SnapStart for a particular Lambda function, publishing a new version of the function will trigger an optimization process.
