VMware | What is a Virtual Infrastructure?
In essence, a virtual infrastructure is a dynamic mapping of physical resources to business needs. While a virtual machine represents the physical resources of a single computer, a virtual infrastructure represents the physical resources of the entire IT environment, aggregating x86 computers and their attached network and storage into a unified pool of IT resources.

Structurally, a virtual infrastructure consists of the following components:

  • Single-node hypervisors to enable full virtualisation of each x86 computer.
  • A set of virtualisation-based distributed system infrastructure services such as resource management to optimize available resources among virtual machines.
  • Automation solutions that provide special capabilities to optimize a particular IT process such as provisioning or disaster recovery.
By decoupling the entire software environment from its underlying hardware infrastructure, virtualisation enables the aggregation of multiple servers, storage infrastructure and networks into shared pools of resources that can be delivered dynamically, securely and reliably to applications as needed. This pioneering approach enables organizations to build a computing infrastructure with high levels of utilization, availability, automation and flexibility using building blocks of inexpensive industry-standard servers.

Virtual Infrastructure Benefits
VMware has made it possible to fully realize the enormous benefits of virtualisation in production-scale IT environments by building virtual infrastructure automation and management capabilities around a best-in-class hypervisor. In fact, 86% of VMware customers use virtualisation in production and 43% deploy most new production applications in virtual machines.

VMware virtual infrastructure solutions are ideal for production environments in part because they run on industry-standard servers and desktops and support a wide range of operating system and application environments, as well as networking and storage infrastructure. We have designed our solutions to function independently of the hardware and operating system to provide customers with a broad platform choice. As a result, our solutions provide a key integration point for hardware and infrastructure management vendors to deliver differentiated value that can be applied uniformly across all application and operating system environments.

VMware customers who have adopted our virtual infrastructure solutions have reported dramatic results, including:
  • 60-80% utilization rates for x86 servers (up from 5-15% in non-virtualized PCs)
  • Cost savings of more than $3,000 annually for every workload virtualized
  • Ability to provision new applications in minutes instead of days or weeks
  • 85% improvement in recovery time from unplanned downtime

Citrix XenServer
Virtualisation for every server in the enterprise.
Any Server. Anywhere. Anytime.
Citrix XenServer™ is server virtualisation that makes datacenters more agile and efficient through faster application delivery, higher levels of availability and improved utilization of IT resources.

XenServer delivers the advanced features required by mission critical workloads without sacrificing the ease-of-use necessary for wide-scale deployments. The unique provisioning technology of XenServer can rapidly deliver workloads across virtual or physical servers making it the ideal virtualisation platform for every server in the enterprise.

Uniquely open
XenServer is based on the open source Xen® hypervisor, an exceptionally lean technology that delivers low overhead and near-native performance. Leveraging both Intel® VT platforms and AMD® Virtualisation (AMD-V™) platforms for hardware assisted virtualisation, XenServer delivers faster, more efficient virtualisation computing.  Unlike other virtualisation products that are built on closed proprietary systems, XenServer’s open APIs allow customers to access and control advanced functions from their existing server and storage hardware.

Radically simple
Citrix establishes a new standard in ease-of-use by including new configuration wizards, intuitive interfaces and easy point-and-click conversion of physical servers into virtual machines.  Experience 10 to Xen as it only takes 10 minutes to install and configure XenServer.  XenServer gives administrators the visibility to easily keep track of virtual machines as they proliferate across large datacenters.  Web 2.0 style tagging and searching capabilities allow IT professionals to assign metadata and virtual tags to workloads, either pre-defined or customized to each organization’s needs.  XenServer’s performance monitoring, reporting and alerting dashboards make it easy to see both real-time and historical views of virtual machines and physical host performance over long periods of time with virtually no storage or performance overhead.

Seriously powerful
Ready to get serious about server virtualisation? Building on long list of proven enterprise-class features such as live migration, resource pooling and workload provisioning, the newest version of XenServer adds more than 100 new virtualisation enhancements including advances in high availability (HA) and disaster recovery. These capabilities include the industry’s most advanced HA, auto-restart and failover technologies that can be seamlessly upgraded to full fault tolerance for the most mission-critical applications.
