AWS Lambda is an event-driven, serverless computing platform provided by Amazon as a part of the Amazon Web Services. It is a computing service that runs code in response to events and automatically manages the computing resources required by that code. Now, let us, deep dive, into this tutorial and understand what AWS Lambda actually is. Below topics are explained in this AWS Lambda Tutorial: 1. Features of AWS Lambda (02:31) 2. What is AWS Lambda? (03:55) 3. Where is AWS Lambda used? (04:52) 4.
