Questions tagged [aws-lambda]
AWS Lambda is a compute service that lets you run code without the overhead of managing servers. Questions using this tag should be about interacting with this service in a programming context (e.g. via API calls) or about code running on this service. (Not to be confused with the [lambda] tag, which instead refers to a type of function).
