Is it beneficial to use multiple types of virtualization software together? The answer: yes. Combining complementary virtualization technologies provides a stronger, more robust solution that reduces costs, maximizes return on investment (ROI), and minimizes the number of servers to manage. By consolidating these technologies, organizations can get the most out of the application, hardware, and operating system (OS).

When considering any software solution, two things come to mind: flexibility and cost. With virtualization technology, multiple applications can now be hosted safely and securely on a single server, eliminating the overhead of running multiple operating systems (OS) per server. This capability can greatly reduce costs and help organizations deliver consistent service levels despite unpredictable workloads.

Any organization that deploys multiple same-application servers with regularity could benefit from virtual appliances. Virtualization solutions eliminate the need to copy an operating system (OS) and application into each virtual environment, by creating a single, centrally installed master copy instead. It saves time on installation and enables greater levels of efficiency, manageability, flexibility, and resource use.

Cox Communications, a leading cable provider, needed to find a way to centralize the IT requirements of its customer support team. With over a hundred users, its challenge was to move from single desktop applications to a centralized server which would offer many concurrent instances of the application—and minimize the cost. By deploying a virtualization solution, Cox realized a return on investment (ROI) of 300 percent.

When Katrina hit in 2005, Murphy was among the many companies impacted by the devastation. Although its servers sustained no physical damage, they were inaccessible, and Murphy could not reach or use its data until the waters receded and the servers were moved. After retrieving the servers from New Orleans (US), the company went directly to Virtuozzo for an evaluation.

The playing field for server virtualization has become much more crowded over the last few years. It can be very time-consuming to digest each vendor’s marketing materials to find the right solution for your organization. That’s why you need to be aware of the main considerations and basic differences between the technologies, to find a starting point for technology evaluation.

Historically, IT administrators have provisioned new servers with every new application, resulting in a large number of servers with utilization rates of 10 to 15 percent or less, commonly known as server sprawl. Server sprawl is responsible for a range of costs, including infrastructure, hardware, software, and management costs. So why hasn’t hardware virtualization solved your server sprawl issues yet?

Today’s information technology (IT) organizations are dealing with the consequences of exploding infrastructure complexity. At the root of the problem is uncontrolled server sprawl—servers provisioned to support a single application. Organizations that have implemented hardware virtualization have unwittingly created a new problem: operating system (OS) sprawl. IT organizations have to find ways to address this critical challenge—today.
