Questions tagged [amazon-lambda]

This tag is for questions about Amazon Web Services' "Lambda".

AWS Lambda lets you run code on the Amazon cloud without provisioning or managing servers. Lambda takes care of everything required to run and scale your uploaded code with high availability. You can set up your code to automatically trigger from other AWS services or call it directly from any web or mobile app, and pay only for the compute time used.
