Episode Summary

Anyone who’s heard of serverless has heard of cold starts. But have you heard about proactive initialization? This is a newly published service enhancement from the AWS Lambda team that pre-warms execution environments of on-demand functions. This enhancement results in reduced cold start times and costs consumers no extra money to take advantage of. In this short bonus episode, Allen and AJ talk about what you need to know about his exciting optimization. The two cover how it was discovered, why the AWS Lambda team made the change, and what you need to do to get started with it.
