Virtualization.

From a user perspective, server virtualization directly infers to a better consolidation of servers that translates into key advantages like greater agility and flexibility in operations, ease of use and of course substantial costs benefits in terms of lower investment in new hardware and lower operating costs. The underlying purpose of virtualization is to optimize server utilization, enhance availability, speed provisioning and so on.

Compatibility

The implementation of virtual applications can be useful even in a legacy IT system environment, by harnessing the untapped capacities of existing severs, which have remained dormant due to lack of use.

According to Arun Gupta, Group CTO of Shoppers Stop, there are several factors that need to be looked at before making the switch to as virtual environment. These include an evaluation of the server's capabilities, the licensing costs involved to execute the virtual process and significantly the impact of the transition on other software licenses. "Most legacy hardware, doesn't give significant gains when utilized in a virtualized environment," he cautions.


Correct Approach

One of the many mistakes often committed during the transition to a virtual environment involves putting up the virtual applications into a single physical server. A move that could result in a complete service breakdown in case of a server failure. "This should be avoided at all costs," stresses Gupta. "There is a need for resilience and thus a multi-server deployment is always beneficial," he adds.

Return on Investment (RoI)

The licensing cost and the support (cost) remain key concerns for SMBs actively considering the deployment of virtualization technology. Given the fact, that in most cases the cost of IT deployment in an SME is restricted to a miniscule percentage of the overall investment, coupled with ambitious RoI expectations, it comes as no surprise that the pace of adoption of virtualization technology in India hasn't lived upto expectations.

Key Benefits

The major advantage of virtualization application is its enhanced scalability, especially when all applications are not peaking at the same time. It also reduces the hardware footprint thereby easing the overall management. Further, it also offers other benefits like a low heat footprint leading to lower costs for maintaining virtualized settings, low power consumption, reduction in space requirements, and ultimately reduction of the cost of running a data center (or a rack of servers) for SMBs.

TYPES OF VITUALIZATION


Server Virtualization – consolidating multiple physical servers into virtual servers that run on a single physical server.


Application Virtualization
– an application runs on another host from where it is installed in a variety of ways. It could be done by application streaming, desktop virtualization or VDI, or a VM package (like VMware ACE creates with a player). Microsoft Softgrid is an example of Application virtualization.

Presentation Virtualization – This is what Citrix Met frame (and the ICA protocol) as well as Microsoft Terminal Services (and RDP) are able to create. With presentation virtualization, an application actually runs on another host and all that you see on the client is the screen from where it is run.
Network Virtualization – with network virtualization, the network is “carved up” and can be used for multiple purposes such as running a protocol analyzer inside an Ethernet switch. Components of a virtual network could include NICs, switches, VLANs, network storage devices, virtual network containers, and network media.


Storage Virtualization – with storage virtualization, the disk/data storage for your data is consolidated to and managed by a virtual storage system. The servers connected to the storage system aren’t aware of where the data really is. Storage virtualization is sometimes described as “abstracting the logical storage from the physical storage.

Hey friend, thanks for sharing such a nice article on the visualization and explaining the whole concept. Well, i have also got some important information and want to share it with you. So please download and check it.
