Server virtualization provides a cost-effective computing proposition to large as well as small business enterprises. A superlative virtual server maximizes resources utilization, enhances the overall security of the network, and makes disaster recovery effortless and economical. However, lots of myths are prevalent about server virtualization that prevent entrepreneurs from adopting this gainful technology. In the following paragraphs we shall deflate some myths and state a few astounding facts about virtual servers.
* Virtual server can burn a big hole in the pocket
The primary objective of virtualization is to help you to save money. Different kinds of virtual servers are available in the market. Their prices are highly variable, and depend upon their type and efficiency. With proper capacity analysis and planning, you can certainly enjoy the benefits of server virtualization at the lowest price.
* Virtual machines are more vulnerable to security threats
Virtual machines are neither more nor less secure than ordinary physical systems. In fact, due to consolidation of servers it becomes relatively easy to make security foolproof in a virtual environment.
* Server virtualization is difficult to operate and manage
Virtual systems behave in a similar manner as their physical counterparts. Windows and Linux services change a little bit in a virtual environment, but you don’t need special skill set or knowledge to operate and manage the virtual machines.
* Applications don’t migrate easily on virtual servers
Any application that is able to run on a physical machine will also be functional on a virtual system. Barring a few, most applications are easily able to migrate on a virtual server.
* Virtual servers are not that efficient
Some years ago, virtual servers were surely not as efficient as physical servers. However, in the present day because of tremendous advancement in technology, virtual machines exhibit more resilience and efficiency. With high-performance hard disks, virtually compatible CPU, storage-area networks and gigabit Ethernets, virtual machines definitely give better performance.
* Backup and data recovery are not easy
With respect to virtual servers, backup and recovery time is quite less. The restoration process typically involves the replacement of damaged files with undamaged virtual files. If done appropriately, the process can be complete in a few minutes. The usage of conventional backup technology can prolong the disaster recovery process.
* Server virtualization and licensing problems go hand in hand
Like the physical servers, virtual machines have to follow a set of licensing constraints and regulations. If you use software applications that are specifically made for the virtual environment, you will not face any sort of licensing troubles.
* Virtualization creates unmanageable sprawl
Although it is easy to set up virtual machines, but server virtualization doesn’t create any kind of sprawl. It basically maximizes the utilization of hardware resources. The number of virtual machines set up depends upon the availability of computing resources and dexterity of the IT manager. In a nutshell, server virtualization is an effective way to cut down operation and maintenance overheads significantly. By using this innovative technology, a virtual office can be set up any where without worrying too much about space, equipments and manpower.
