Hyperconvergence is a term which describes an approach to building datacenter infrastructure that was developed by companies like Amazon, Google, and Facebook for their hyperscale computing platforms.
Amazon, Google and Facebook pioneered what we now call Hyperconverged Infrastructure (HCI) as a way to lower the cost and complexity of their hyperscale computing platforms.
They recognized that the traditional way of deploying and managing infrastructure (separate silos of compute, network, and storage, utilizing proprietary vendor hardware) was far too costly, complex and cumbersome.
They understood that the real intelligence and functionality resides in software and that the proprietary hardware was merely an expensive wrapper. So, they developed an approach that tightly integrated the virtualization, compute, network, and storage functionality at the software layer and ran it on commodity servers that could be deployed in massive scale-out compute grids which are easily managed with fewer resources.
Once this approach was implemented and proven by the hyperscale companies, several vendors commercialized it and the Hyperconverged Infrastructure (HCI) sector was born. HCI is currently one of the fastest growing segments in the IT market because customers can achieve the simplicity and agility of cloud without migrating their environments and experiencing the latency concerns and lack of control that is intrinsic with a migration to a public cloud environment.
