Software-Defined Data Center Platform

The Software-Defined Data Center (SDDC) platform supports any device, any app and any cloud. It brings together VMware's compute, storage and network virtualization into a natively integrated stack, delivering enterprise-ready cloud infrastructure capabilities that are common to both private and public clouds.

Compute Virtualization

Modern software-defined compute, also known as virtualization, is the first step toward the Software-Defined Data Center. Introduced by VMware more than a decade ago, x86 server virtualization has become a standard technology used by a vast majority of data centers worldwide.
Servers deployed the conventional way operate at less than 15 percent of capacity. Virtualization rewrites the entire equation. CPU and memory are decoupled from physical hardware, creating pools of resources for use wherever needed. Each virtualized application and its operating system are encapsulated in a separate, isolated software container called a virtual machine (VM). Many VMs can be run simultaneously on each server, putting the majority of hardware capacity to productive use.

The results have transformed server effciency by offering:
Superior performance
Higher availability
Significant savings

The result: IT achieves significantly more at dramatically lower cost through virtualization.

Network Virtualization

What is network virtualization, and how does it differ from software-defined networking (SDN)?
In contrast to SDN, in which hardware remains the driving force, VMware network virtualization technology truly decouples network resources from underlying hardware.
Virtualization principles are applied to physical network infrastructure, abstracting network services to create a flexible pool of transport capacity that can be allocated, utilized and repurposed on demand.

How Do Virtualized Networks Work?

In a close analogy to the virtual machine, a virtualized network is a software container that presents logical network components-logical switches, routers, firewalls, load balancers, VPNs and more-to connected workloads.

These virtualized networks are programmatically created, provisioned and managed, with the underlying physical network serving as a simple packet-forwarding backplane. Network and security services are allocated to each VM according to its needs, and stay attached to it as the VM moves among hosts in the dynamic virtualized environment.
