Hyper-convergence (hyperconvergence) is a type of infrastructure system with a software-centric architecture that tightly integrates compute, storage, networking and virtualization resources and other technologies from scratch in a commodity hardware box supported by a single vendor.
A hyper-converged system allows the integrated technologies to be managed as a single system through a common toolset. Hyper-converged systems can be expanded through the addition of nodes to the base unit. Common use cases include virtualized workloads.
Hyper-convergence grew out of the concept of converged infrastructure. Under the converged infrastructure approach, a vendor provides a pre-configured bundle of hardware and software in a single chassis with the goal of minimizing compatibility issues and simplifying management. A hyper-converged system differs from a converged system in its tighter integration of the software components, which may expand beyond compute, storage, networking and virtualization to also include technologies such as WAN optimization or data deduplication and compression.
