Some facts about virtual servers over physical servers!

Enterprises which haven’t virtualized their server environments will always buy a whole new server every time they run out of computing space. But this practice might not prove advantageous always. On the other hand, virtual servers could see a business maximize profits and become more responsive in a volatile business climate.

In this article, we will discuss about the pros and cons to consider before going for a physical or a virtual server.

Reasons to move to a virtual server

Cost savings- Every business tries to make profits and so spending the money in the right direction is also important. A virtualized computing environment allows multiple physical servers to be configured to increase or decrease the number of logical servers. This means businesses might get flexible to spend on any additional physical servers.

Time saving- In virtualized server environments, bootable images and virtual server templates can be kept on hand for when they’re needed. This saves a lot of time while installing and re-installing windows, configuring firewall settings, restoring backups.

Makes testing easier- Virtualization helps in testing a new configuration or a new sales application, only to discover that you didn’t have the necessary hardware. Testing new hardware and software is crucial to the continuity of any business making use of IT. For more elaborate set-ups or labs, a dedicated virtual server environment allows testers to configure and reconfigure various scenarios with ease. By doing so, a lot of time is saved for the admin.

Quick Recovery- With proper application installs and network settings live systems can be made redundant with an equivalent or similar server environment running alongside it. This server environment doesn’t have to be active always. But can act as a backup when need arises.

Reasons not to move to a virtual server

The problem with virtual servers is that they are loaded onto physical servers and if a physical server suffers a mechanical fault, all the virtual servers will be affected. This can spell serious financial consequences if there’s prolonged downtime. However, nowadays those who are presenting enterprise grade servers are offering redundant computing machines which have dual hardware meant for coordinated functioning. They are so intelligent that if one goes down, the other takes on the functions immediately in an automated way. For this reason, these appliances are called as highly available server appliances.

Performance degradation- Usually, separate applications might be installed on separate virtual servers, but these programs are still inextricably linked- means they share the resources of their underlying/supporting physical server. As the demand from more Virtual Servers is placed on the physical server, a serious degradation in performance could be experienced across the board, and could negatively affect service oriented or real time business operations.

Licensing Limitations- Some applications might not work on shared environments and could even be in breach of the licensing agreement. Furthermore, depending on which operating system you choose to go with, make sure it’s properly licensed for your environment. Otherwise, there could be a significant cost impact depending on whether it’s installed on a physical or number of virtual servers.
