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. If required, however, the technologies in a converged infrastructure can be separated and used independently. The technologies in a hyper-converged infrastructure, however, are so integrated that they can not be broken down into separate components.
