}With which of the following can you run code without provisioning or managing servers and pay only for the compute time consumed (there is no charge when the code is not running)?
AWS Lambda lets you run code without provisioning or managing serverswhy aws lambda is called lambda
In programming, a Lambda expression (or function) is just an anonymous function, i.e., a function with no name.Copyright © 2021 Codeinu
