What is Serverless Computing in Cloud?

Serverless computing is a computing paradigm that allows developers to develop/deploy and execute applications or services without considering about servers that are required to host that application. Applications developed/deployed using this concept don't require you to provision, scale, and manage any servers. You can build highly available, scalable, and fault-tolerant applications or backend services. Everything that is required to manage your application is handled by the developer. The term serverless can be a misnomer because in the backend there is a physical server hosting our application but the thing is these servers are managed by the cloud service provider, not the developer itself.

Building serverless applications reduce the developer's work to a handsome extent. The headache to manage and operate the server is eliminated so that developers can focus on their core product. The reduced overhead lets developers reclaim time and energy that can be spent on developing an efficient and reliable product.

Serverless computing is an emerging concept that has somewhat exploded in terms of popularity in the market. This is in part due to AWS (Amazon Web Services) Serverless offering, AWS Lambda as well as Azure's newly released Functions.

Benefits of Serverless Computing

The following are the most common benefits of serverless computing:

  • Cost efficient: Capital investment to develop the application is minimal and payment is only for the time when the code is being executed. There is no idle time payment.
  • No server management: Serve management is a tedious task so no server management provides relief for developers.
  • Flexible scaling and Automated high availability: Applications are highly available as this becomes the responsibility of the cloud service providers.
