A virtual data center (VDC) is an abstraction that is not tangible of physical IT infrastructure components specifically designed to meet business requirements for enterprises. Virtualization technologies allow the VDC to provide the same compute data storage, networking and data access capabilities of traditional IT infrastructure, while decreasing costs, complexity and maintenance.
Virtualization enables quicker provisioning of hardware, as well as on-demand scaling in order to meet the demands of business growth. It supports agile software development and DevOps practices making it an ideal fit for modern IT architecture. It also lowers IT costs for support and labor and allows companies to invest more in technology.
VDCs are built on-premise in central physical locations (private cloud), or hosted by a third party which provides cloud services to several businesses simultaneously (public cloud). In either scenario, the virtualization of the platform will reduce the cost of maintenance and operations.
Physical hardware required for building and setting up the VDC is available from vendors or be leased by an IT managed service provider. It’s sometimes referred to as hyperconverged infrastructure (HCI) because it blends computing, storage and network equipment into an integrated system that runs on software platforms and can scale up and down.
A VDC can run on a variety of operating systems, including Linux, Windows, and VMware. It can be utilized in a hub-and-spoke design with the core infrastructure installed in the hub and workloads and applications placed in spokes. This design is in line with the organization structure of roles and responsibilities, while providing lower costs through component and data flow centralization and more efficient management, operations and compliance.
