What is software-defined data center?
Software- defined data center (SDDC), also called as virtual data center (VDC) is a data storage technique in which all elements of the infrastructure such as networking, storage, CPU, and security are being virtualized and delivered as a service. The process like deployment, configuration, provisioning and operation of the entire IT infrastructure is abstracted from hardware and implemented through software. Virtualization is central to the software-defined data center (SDDC). The three main components of SDDC are: Network, Storage and server Virtualization.
Network Virtualization: It is a technique of combining available resources in a network by dividing the available bandwidth into the channels, each of which is independent from others, and each of which can be assigned to a specific server in a real time environment.
Storage Virtualization: It involves the pooling of physical storage from multiple network storage devices into what seems to a single storage entity that is managed from a central controlled location.
Server Virtualization: It is the process of masking the server resources such as the number and identity of individual physical servers, operating systems, and processors from server users.
