AWS Lambda is  an Amazon service which offers serverless computing

 Let me first explain you what is serverless computing:

  • Serverless computing lets your application run without any worries  regarding server management, because the server in which application is running is completely managed, provisioned and scaled by AWS platform
  • Your work is to write code (lambda function) in any preferable backend language and execute it, lambda as a backend service will respond to all the events associated with your application

Working mechanism of AWS Lambda:

  1. Write your code (lambda function) to AWS Lambda Console ( lambda function includes the tasks that AWS lambda is suppose to perform)
  2. Set Lambda to receive a trigger to function, from any mobile app or Http endpoint or AWS Service (event sources)
  3. On receiving the input trigger the lambda starts executing the code using the required compute resources
  4. You have to pay only for the time-spam the function remains in execution state

AWS services used to integrate with Lambda to set the event source are:

I hope this helps you, happy learning :)
