Virtualization has changed the ability of IT to deploy and manage compute infrastructure and lent tremendous power and flexibility to the administrator. As a consequence, the transformation has not merely impacted the data centre floor and the inner workings hidden from the business, but it has changed the very nature of computing for the business as well.
At the business layer more and more critical workloads were virtualized , bringing credence to the technology of abstraction of the compute layer.
All of these changes have infused the business with a new ability to depend on IT, and to do so at lower cost and with less risk of disruption.
Whilst all the wave 1 of virtualization was about compute virtualization, the data center was still a maize for the IT admin with network and storage continuing to be discretely managed infrastructure. This was some kind of a convergence that was being managed.
There was further abstraction to follow in the storage layer. The entire storage area network and the storage IOs were further abstracted into a single layer.
The most significant alteration in the hyperconvergence approach is that it starts with storage, and aims to make the most difficult to manage resource in the data center highly efficient, performant, and easy to scale. Hyper converged infrastructure is software defined; which means the infrastructure operations are logically separated from the physical hardware; the integration between components is much tighter than you see with older three tier architecture of compute, SAN and storage. These components have to stay together to function correctly.
Changes now can be made on the software thereby offering a flexible way to handle increasing or changing demands which was not possible with the older converged infrastructure model.
With the hyperconvergence solutions now entering the market, the IT administrator will be able to focus entirely on the server or application, and trust that all of the integrated components transparently work together in the background
