Hyper-converged infrastructure (HCI, also called a hyper-converged integrated system. HCIS) refers to integrating virtualization of storage, computing and networking in a data center into a single appliance.
Why is the industry moving towards this?
Compatibilty out the box : Storage, Networking and Computing providers have come together with their products to offer something out the box that has been thoroughly tested together. No more searching three providers on compatibility when updating a single firmware for a device.

Management : Again single management interface for all your virtulised hardware
Faster setup : You can have new infrastructure setup to expand your ERP system or increase your VDI seat count in less than one hour!
