Private Cloud

A private cloud consists of computing resources used exclusively by one business or organization. The private cloud can be physically located at your organization’s on-site datacenter or it can be hosted by a third-party service provider. But in a private cloud, the services and infrastructure are always maintained on a private network and the hardware and software are dedicated solely to your organization. In this way, a private cloud can make it easier for an organization to customize its resources to meet specific IT requirements. Private clouds are often used by government agencies, financial institutions, any other mid- to large-size organizations with business-critical operations seeking enhanced control over their environment.

Hyper-V is Microsoft's hardware virtualization product. It lets you create and run a software version of a computer, called a virtual machine. Each virtual machine acts like a complete computer, running an operating system and programs. When you need computing resources, virtual machines give you more flexibility, help save time and money, and are a more efficient way to use hardware than just running one operating system on physical hardware.

Hyper-V runs each virtual machine in its own isolated space, which means you can run more than one virtual machine on the same hardware at the same time. You might want to do this to avoid problems such as a crash affecting the other workloads, or to give different people, groups or services access to different systems.

Virtual Machine Manager

System Center Virtual Machine Manager (VMM)! VMM is part of the System Centre suite, used to configure, manage and transform traditional datacenters, and helping to provide a unified management experience across on-premises, service provider, and the Azure cloud. VMM capabilities include:

• Datacenter: Configure and manage your datacenter components as a single fabric in VMM. Datacenter components include virtualization servers, networking components, and storage resources. VMM provisions and manages the resources needed to create and deploy virtual machines and services to private clouds.
• Virtualization hosts: VMM can add, provision, and manage Hyper-V and VMware virtualization hosts and clusters.
• Networking: Add networking resources to the VMM fabric, including network sites defined by IP subnets, virtual LANs (VLANs), logical switches, static IP address and MAC pools. VMM provides network virtualization, including support for creating and manage virtual networks and network gateways. Network virtualization allows multiple tenants to have isolated networks and their own IP address ranges for increased privacy and security. Using gateways, VMs on virtual networks can connect to physical networks in the same site or in different locations.
• Storage: VMM can discover, classify, provision, allocate, and assign local and remote storage. VMM supports block storage (fibre channel, iSCSI, and Serial Attached SCSI (SAS) storage area networks (SANs)).
• Library resources: The VMM fabric retains a library of file-based and non file-based resources that are used to create and deploy VMs and services on virtualization hosts. File-based resources include virtual hard disks, ISO images, and scripts. Non file-based resources include templates and profiles that are used to standardize the creation of VMs. Library resources are accessed through library shares.
