What is virtualization?: Virtualization is a process by which a physical server is partitioned into logical or virtual servers, potentially each with a different Operating System. Each virtual machine (VM) is running in total isolation on the same physical hardware, utilizing its own set of virtual hardware (e.g. CPU, RAM, NIC…). The VM Operating System defines a consistent hardware environment regardless of the actual physical hardware. This hardware consistency means VMs can be moved between physical machines without regard to the underlying hardware configuration.
Is virtualization a new idea?: No. Virtualization is a throwback to mainframe computing of the 1960’s and 1970’s which allowed partitioning of the mainframe for different applications or users. As the PC gained popularity networks and local applications were much less costly than mainframes so the practice was not as widely used.
What are the benefits of virtualization?: Virtualization addresses many different IT issues including: underutilization, escalating management costs, vulnerability to single hardware failure, legacy software, and escalating power costs.
Can any server and application be virtualized?: No, but the number and type of applications that don’t function properly in a virtualized environment is shrinking every day. Certain resource intensive applications, such as databases or voice applications will not perform well in a virtualized environment.

Virtualization

Dynamic Strategies can assist your company in virtualization efforts. Virtualization is a method of partitioning one physical server computer into multiple “virtual” servers, giving each the appearance and capabilities of running on its own dedicated machine. Each virtual server functions as a full-fledged server and can be independently rebooted. Virtualization dramatically improves the efficiency and availability of resources and applications in your organization. Internal resources are underutilized under the old “one server, one application” model and IT spends too much time managing servers rather than innovating.

The DSI Difference

Dynamic Strategies brings real world experience to virtualization. It’s not theoretical to us – we’ve executed virtualization strategies in a variety of companies and seen the benefits.

Beyond reducing infrastructure costs and theoretical-sounding talk of cloud computing, we can make a solid case for virtualization based on our hands on experience, with a metric anyone can understand: time.

A virtualized environment by DSI takes hardware out of the equation and dramatically reduces the time associated with hardware acquisition, setup and maintenance of business applications. A business application can be provisioned, relocated or have its resource allocation changed in minutes; in the past, in a non-virtualized environment, days of productivity might be lost.

Think of a massive enterprise software implementation where a couple of days of lost time are literally worth tens or hundreds of thousands of dollars. Virtualization allows for new testing environments to be created, deployed and recreated in moments, rather than in days that would have had users and consultants waiting while IT did its work. In addition, in case of disaster, old applications can be moved to new hardware, and virtual servers quickly put back into play.

Examples

Dynamic Strategies has created virtualized environments for our customers helping reduce their operating costs. Among the benefits we’ve achieved for our customers are:

Reduced cost for power and cooling – More workloads per hardware chassis means fewer servers to power and keep cool.
Right-sizing of resources for workloads – Yesterday’s data center best practices recommended similar hardware compositions whenever possible for potential cost savings. Yet this practice resulted in a wasteful under-subscription of hardware resources for light workloads. Virtualization provided a better, more efficient use of resources.
Elimination of legacy hardware – Data centers are collections of hardware that were procured for various projects over time, yet maintaining that legacy hardware over extended periods grows to become a liability. Virtualization provided a mechanism to retain the service atop the hardware platform while eliminating the hardware itself.
Reduced total cost of ownership – Improvements in the ability to spin up new services and manage those that already exist reduced the management cost of doing business for IT. These improvements were achieved through significant improvements to the speed in which common IT tasks could be accomplished.
Enhanced agility – Deploying new services and scaling those that already exist grew faster once virtualized due to virtualization's intrinsic ability to rapidly deploy configurations across devices and environments.
