Information Technology Solutions - Server & Desktop Virtualization

Server & Desktop Virtualization

A virtualization strategy can help a company achieve maximum security, efficiency, maintenance agility, and cost effectiveness for both desktops and servers. Implementing virtualization across an enterprise is one of Neteam's primary service offerings.

Server & Desktop Virtualization

Server virtualization is simply the implementation of multiple virtual machines onto a single physical server. Each virtual machines remains entirely insulated from the others, thereby achieving the same rugged security described for desktop VMs. Furthermore, each VM is decoupled from its server host, which allows each VM to run disparate operating systems, system configurations, and applications. This decoupling also accommodates easy migration from one server host to another while maintaining an unbroken functional transition. Server virtualization is a recognized method for accomplishing maximum data enter flexibility, security, and stability.

  • Conservation of physical space through consolidation. It's a common practice to dedicate each server to a single application. If several applications only use a small amount of processing power, the network administrator can consolidate several VMs onto a single server. For larger enterprises, physical space in not an insignificant issue.
  • Achieving redundancy without additional hardware purchases. Redundancy, a term used for running the same application across multiple servers as a fail-safe measure, can be easily implemented by simply configuring identical virtual servers across two different physical servers. The plug and play nature of server virtualization allows complex and time consuming business continuity strategies to be quickly and securely deployed like never before.
  • Virtual test environments for software developers. A dedicated test environment for new applications can be set up quickly and safely on a virtual machine. As each virtual environment is an autonomous entity, any crashes in the test VM will leave the rest of the enterprise unaffected.
  • Seamless Live Migration. Virtual environments are easily transitioned from legacy servers to new equipment while retaining all of their characteristics and functionality. This maintains maximum business continuity and uninterrupted business processes across the network, even in the middle of a major infrastructure upgrade.

Desktop Virtualizaton

Day to day maintenance of your employees' desktops is a time-consuming, imprecise endeavour. Desktop virtualization can alleviate the cumbersome tasks of applying patches, OS upgrades, and new application by allowing administrators to employ virtual machine (VM) images, or templates for VMs, which are applied to all employees' desktops. All VM images are applied by the administrator from a central location. Different images are applied to users depending on their company role. An employee at the help desk, for instance, would have a different image loaded on their desktop than a sales rep or a software developer.

A virtualized image/template contains the full installation of the operating system, all necessary drivers, applications, and a customized internet configuration. It is essentially a full desktop deployment defined, managed by, and overseen by a single IT administrator. Such deployments work best where many employees need essentially the same functionality.

Because the VM is abstracted and separate from the computer's hardware and other VMs, extremely strong security is achieved and easily maintained. Centralized security greatly reduces the possibility of an introduction of malware or virus into the enterprise, or an external anomaly that may compromise a company's network-resident data.

In many organizations, there is a natural tension between employees who want to have a desktop environment they can control and install applications on, and IT staff who would prefer that computers be locked down and kept safe from malware and attacks that might compromise company information.

Desktop VMs can be installed on either a server or the desktop PC itself. What type of implementation depends on such factors as the number of remote employees accessing the network, how much functionality and processes an organization needs to virtualize, and the nature of the business itself.

If your organization has not yet investigated desktop or server virtualization, it soon will. The myriad advantages of this networking and deployment model are too large and compelling to ignore. A Neteam representative can detail all of the options available for virtualizing either some or all of your data center, and describe some of the major solutions offered by industry leaders like VMware and Citrix.
