Cloud

April 20, 2020

Serverless computing does not mean without servers but removing ownership and management of servers. Serverless does not mean harnessing new technology or skills but leveraging these from services providers.

Serverless computing enables businesses to focus on their primary service rather than on underlying IT infrastructure like networks and server operating systems. The prime advantage of this cloud computing model is that it can drastically channelize your IT spends on things that really matter rather than excessive burdens due to routine costs like licensing, hardware and software installation, support and maintenance, etc. More importantly, it also saves your time, money and efforts on hiring and maintaining specialist workforce to perform these tasks.

The serverless architecture allows not just scalability but also elasticity, which means you do not need to spend time and money on creating and/or implementing autoscaling policies. The respective cloud service provider takes care of the same and ensures that your serverless applications integrates seamlessly to deliver optimal results, irrespective of the demand fluctuations. Some of the leading serverless platform providers include Amazon, IBM, Google and, Microsoft.
