While cloud computing has had a profound an impact on IT, the level of technical innovation associated with the cloud has been relatively slight. Virtual machines that were once run in a local data center have been moved to a highly automated shared public cloud that exposes underlying infrastructure using application programming interfaces (APIs).
But over the past year, increased innovation in the cloud has spawned multiple architectures that will compete to run a variety of application workloads. In addition to traditional virtual machines, it’s now common for containers to be deployed on public clouds. Beyond containers, however, serverless computing frameworks are starting to emerge that promise to radically alter the economics of cloud computing. In fact, a new report published by 451 Research suggests that serverless computing will be the least expensive cloud option by a wide margin for certain classes of workloads.
