Lambda Summary

Lambda logo

  • Lambda is a serverless compute service.

  • It takes care of provisioning/managing the services that you use to run your code

  • You don’t have to worry about OS or scaling

  • Allows you to run code for nearly any type of application or backend service

  • Can write Lambda functions in a range of different languages e.g. Node.js, Python, Go etc.

  • Can be used as an event driven service — e.g. can trigger from another service.

  • Can be a compute service to run code in response to an HTTP Request using API Gateway.

  • Pay for number of requests (first million free) and also pay for the duration of code running.

  • As invocations increase, the Lambda functions scales automatically.
