A reliable industry-proven hypervisor is a critical foundation of a virtualized infrastructure but is not a complete solution by itself. You need an IT services platform that delivers the right infrastructure and application services for running your business – a private cloud. It must include built-in migration, aggregation, allocation, power management, and availability services.
VMware vSphere is the only virtualization platform that delivers all of these built-in services.
- Live Migration: Transparent Agility
- Aggregation: Shared Pools of Resources
- Allocation: Elastic Pool of Resources
- Power Management: Intelligently Save Power
- Availability: Flexible, Uniform High Availability

Availability: Flexible, Uniform High Availability
" The university has virtualized 50,000 Exchange 2007 mailboxes on VMware Infrastructure. We not only have a more manageable and flexible Exchange environment, but we have replaced Microsoft clustering with VMware’s built-in high availability solutions such as HA and VMotion. We couldn’t be happier with the uptime and performance of our Exchange implementation on VMware. "
— Adrian Jane, Infrastructure and Operations Manager, University of Plymouth
A shared IT services platform for a private cloud needs to improve application availability by providing capabilities to protect against planned infrastructure downtime and provide resilience to unplanned downtime across all aspects of the hardware – server, component, storage, network and software. VMware's offering does this with wide ranging capabilities to protect applications from:
- Total site failure: VMware vCenter Site Recovery Manager
- Planned downtime : VMware VMotion, VMware Storage VMotion
- Unplanned downtime: HA (host and VM failure monitoring), VM-level fault tolerance, NIC teaming
The inherent reliability of VMware ESX is also a big factor here, ensuring that no new risks are introduced into the environment because of the hypervisor.
VMware High Availability provides cost-effective high availability for any application running in a virtual machine without the cost or complexity of traditional clustering offerings like Microsoft Clustering Services (MSCS). Regardless of the guest operating system or underlying hardware configuration, VMware HA provides protection across your entire virtualized IT, eliminating the need for dedicated stand-by hardware. VMware HA is a more scalable solution than clustering options, making it suitable for an organization’s entire infrastructure. VMware HA can now support up to 32 nodes in a cluster (vs. the 16 of Windows Server 2008 Cluster Server 64-bit), improving availability for critical applications by scaling across a larger number of VMware ESX hosts.

VMware Fault Tolerance provides zero downtime and zero data loss availability for all virtual machines against x86 hardware failures. Enabling fault tolerance for a specific virtual machine enables that workload to run on two different ESX hosts simultaneously and allows the virtual machine to run seamlessly in the event of hardware failure on either host. Neither Microsoft nor Citrix has this capability built into its virtualization platform – they both ask customers to purchase a separate 3rd party product to get this type of VM-level fault tolerance. The problem is, beyond the additional cost, that the 3rd party solution is still not available for Hyper-V and for XenServer, the 3rd party solution only supports Windows Server 2003 and Windows Server 2008 virtual machines.
