Serverless architecture with Lambda

AWS Lambda is a compute service. It is called a  serverless architecture because you will not provision or manage any servers. Your code will execute whenever you need it. It will scale automatically to 1,000 requests per second.

You will pay for the compute time that you consume to run the code; there is no extra charge when the code is idle. You can virtually run the code for any type of application and backend service, with zero administration.

AWS Lambda provides high-availability compute infrastructure to perform the administration of resources. This includes operating systems and server maintenance, automatic scaling, capacity provisioning, code monitoring, and logging.

You need to write your code in an AWS Lambda supported language; currently AWS Lambda supports Java, Node.js, C#, Go, and Python.

AWS Lambda is also known as event-driven architecture. It will execute the code in response to any events, such as if file is uploaded or downloaded into an...
