Virtual Machine Manager (VMM) is a management solution for the virtualized datacenter, enabling you to configure and manage your virtualization host, networking, and storage resources in order to create and deploy virtual machines and services to private clouds that you have created.

In Microsoft private cloud solutions, VMM is the management solution for virtualized resources. In the context of cloud computing, virtualization now encompasses three disciplines. In addition to server virtualization which many IT professionals are familiar with, network virtualization and storage virtualization are included as the three resource pools to together form the so-called fabric.

VMM 2012 and later has the (fabric) abstraction architected in. Designed with constructing and managing fabric in mind, VMM has becomes a key enabler in implementing a private cloud solution. In cloud computing, fabric is an abstraction signifying the ability to discover, identify, and manage a resource.
And there are three resource pools: Compute, Network, and Storage integrated with one another to collectively form the fabric. Namely a resource added into one of the three resource pools will by default become part of the fabric and automagically a managed object. Here the Compute pool represents all resources relevant to the computing power, cpu cycles, and execution of code. The Network pool is how resources are glued together or isolated. And the Storage pool is where digital assets are stored.

In VMM the Admin Console  substantiates the concept of fabric and the three resources pools with visual presentations. Clicking the Fabric workspace will display the three resource pools on the navigation pane as Servers (as Compute), Networking, and Storage. Each pool includes groups of components and configurations to support designated functions. One major part of building a private cloud is to establish the three resource pools by adding and configuring server, network, and storage virtualization solutions and components into an associated resource pool. Above the fabric are resources available for consumption. While under the fabric are three resource pools managed by VMM offering computing power, networking capabilities, and storage space to fulfill requests with elasticity. Fabric offers simplicity and shield a user from those complexities under the hood.
