Myths and truths about virtualization

There is nothing to fear about virtualization. It is not complex and not problematic. When considering the deployment of virtualization in your company, consider the following points:

It is necessary to make a return on investment analysis (ROI) to determine the type of virtualization ideal for your company.

Virtualization is a proven technology that has been adopted by many companies and has resulted in significant advantages in terms of IT efficiency, reduced costs, increased flexibility and availability.

With adequate training and resources, the implementation and administration of a virtual environment is easy. In fact, the management of a virtualized environment may require less time and require less resources than a physical environment.

In this article you will find some of the concerns about virtualization that actually are more rumors, that will help you distinguish between reality and fiction.

Myth 1: Virtualization is very expensive

For many companies the combination of software cost (hypervisor and management tools), training and associated hardware (servers and storage) can seem overwhelming. But while the investment is needed, a virtualization solution consolidate servers, by itself, represents a saving in operating costs (energy, maintenance, etc. administration) ehardware. In addition, the major virtualization providers offer free products to give you the opportunity to test the waters. There are options to share your storage server and there are many training solutions that include training courses for computers, books, online communities and of course instructors.

Myth 2: Virtualization requires experience and specialized skills

Nothing could be further from the truth. The planning and implementation of a virtualization project using existing skills and competencies in a typical IT department. The knowledge required to operate the hardware can be easily applied to a virtual environment. In addition, operating systems and applications in a virtual solution behave similarly to physical environments. Organizations should choose a service provider and trusted IT partner that can support teams dedicated to providing them guidance throughout deployment and expansion. And yet, the major virtualization vendors offer tutorials.

Myth 3: Virtualization impact on income

One of the most popular myths associated with virtualization is the impact on performance. The reality is that today’s servers use between 5% and 10% capacity, leaving plenty of room for consolidation and virtualization platform. In March 2012, the Confio1, software company, conducted a parallel test to compare Oracle’s performance in physical and virtual environments. The result was essentially the same in both platforms.

Myth 4: A virtual server is less secure

A virtual server is as safe as a physical, with the same configuration. Every company should develop their own safety standards, as well as its policies and procedures to ensure they are met. In fact, many companies with extreme safety requirements, such as the US Department of Defense, use virtualization as a method to reduce costs. DISA, a division of the Department of Defense sponsors a site for its contractors on cybersecurity, IASE. There are deployment of security techniques guides. In addition, virtualization vendors offer safety courses to teach you manage and protect your data and their platforms.

Myth 5: The license management is complicated

It is true that virtualization has specific requirements with regard to licensing. You must be aware of licenses for virtualization platforms, virtualization, management, operating system and the applications installed on each virtual machine. According to Mark Bartrick3 of Forrester Research, to ensure that you comply with the legal requirements for licensing and to benefit from reduced costs in hardware and energy maintenance, more efficient use of resources and a simplified management should:

Understanding the virtualization rules of each supplier, because everyone has different requirements and change frequently.
Report the licensing requirements and changes to the IT department clearly and regularly for compliance with the rules.
Using tools of virtualization vendor or third parties who are responsible for managing the licenses automatically to reduce your workload and costs.

Myth 6: It is only for large companies

This is another misconception. Virtualization benefits all sizes of companies, from using more than one server. In addition to consolidation of workloads, virtualization offers, among other advantages, greater availability of resources, fault tolerance and disaster recovery. These characteristics, as well as the others mentioned here, can help companies of all sizes to reduce infrastructure costs and simplify management and maintenance.

With these concepts clearer, it’s time to virtualize their infrastructure.
