Serverless Computing: How to Pay for Just the Compute Cycles You Actually Use

By Dick Weisinger

Serverless Computing (or Function-as-a-Service — FaaS) is estimated to be a nearly $8 billion market by analyst firm Markets and Markets. The serverless market is growing at an annual rate of 25 percent.

Serverless has the advantage of lower setup and maintenance costs over traditional IT architectures because it eliminates the need to purchase, setup, and maintain hardware and standard software components like databases and application servers.

Stefan Bergstein, Senior Solution Architect at RedHat, said that “in the near future we will see further adoption of serverless, especially in public clouds. The large cloud providers are going to invest into maturity, programming languages coverage and improved IDE integrations. These aspects will drive adoption.”

Dhwani Shah, a Lead Information Security Engineer at Fifth Third Bank, said that “serverless is cost-effective. Indeed, most hosts will only charge for the execution time. So, instead of paying for servers that are sitting there charging you money, you’re able to reduce the cost of your application to only when it needs to run. For instance, if you have a small-medium business website that’s not insanely trafficked, you could run it for a couple hundred dollars a month.”

Owen Rogers, 451 Research research director, said that “serverless is more than just hype; it has the potential to transform the way we develop, build and run applications in the cloud. Understanding the economics of serverless technology is vital to understanding its potential to disrupt the industry.”
