Serverless Computing 101— What is it? Is it actually server-less
If you are active in the tech industry, you must have heard of the term Serverless. Is it actually server-less? What exactly does serverless computing actually mean. In this article I will be explaining serverless computing and we will see if Serverless computing is actually server-less.
What is Serverless Computing
Serverless computing (or serverless for short), is an execution model where the cloud provider (AWS, Azure, or Google Cloud) is responsible for executing a piece of code by dynamically allocating the resources. And only charging for the amount of resources used to run the code. The code is typically run inside stateless containers that can be triggered by a variety of events including http requests, database events, queuing services, monitoring alerts, file uploads, scheduled events (cron jobs), etc. The code that is sent to the cloud provider for execution is usually in the form of a function. Hence serverless is sometimes referred to as “Functions as a Service” or “FaaS”. Following are the FaaS offerings of the major cloud providers:
- AWS: AWS Lambda
- Microsoft Azure: Azure Functions
- Google Cloud: Cloud Function
