Serverless computing’s major advantage is that we only pay for the resources that we are using. This can result in cost savings when we have a highly variable load, a load with short bursts, or otherwise cannot fully utilize our servers for most of the time.

Serverless instances are in preview mode as of the time of writing this book (summer...
