Virtualization is a combination of software and hardware engineering that lets you create many virtual machines inside of one physical machine which is running on a single operating system. Virtualization technology manages itself with perceived activity and utilization, giving and sharing resources wisely as needed. With particular emphasis on Greener Technologies, reducing the carbon foot print, virtualization has taken the lead in reducing power and space requirements for computers. In this article we will tell you about what are the advantages of virtualization, it might even help you putting a business case or a sales pitch before your supervisor to get going on the virtualization path
Virtualization saves costs and reduces carbon footprint:
You no longer need individual physical servers for performing dedicated tasks. With Virtualization you can have one physical server host many virtual servers. This saves rack space, power and hardware costs. You can re-task your hardware to better things. Modern day virtualization platforms such as Microsoft's Hyper-V is included with the Windows 2008 R2 SP1 server and you do not need to pay additional costs for licensing. Other leading edge Virtualization technologies from VMWare do provide alternatives such as VMWare server in addition to their licensed software. The smaller carbon foot print makes virtualization a green technology, benefiting our future generations
Virtualization provides Centralized Monitoring and Maintainence:
With centralized monitoring and maintenance, modern day virtualization platforms provide an easy way of connecting, monitoring and maintaining your virtual infrastructure, gone are the days when you had to either walk to each server or log on to it remotely via a separate process to perform maintenance on it. Centralized monitoring and alerting capabilities are definitely a plus.
Your virtual hardware never gets old:
Have you ever been in a situation where you had been running an old application on an old piece of hardware and it had become unsupported from the hardware vendor and suddenly a part fails. You scramble on eBay to see if you can still find the part ? Well, with virtualization, that worry is gone forever, your hardware is virtualized and it never becomes outdated or redundant and upgrading it only means few mouse clicks
Virtualization provides High Availability:
HA or High Availability is a big plus of virtualization. You can very easily configure two or more nodes in a cluster on a SAN and have full redundancy. With cluster fail-over set up using virtualization, you can do maintenance on one host while the other continues to serve data and applications. This is an essential feature for Business Continuity and Disaster Recovery.
Virtualization allows for Load balancing and Thin Provisioning:
In a virtualized environment you can have two or more hosts which provide automatic load balancing for your virtual machines and server, if one host is under utilized or over utilized, load balancing features perform automatic live migration of virtual machines from one host to another without having any downtime at all. Your storage is no longer limited to allocating the data blocks per volume or drive up front, but it can now be thin provisioned, meaning, it can dynamically allocate storage on as needed basis.
Virtualize your network not just your desktops and servers:
With virtualization solutions like VMWare's V-Sphere and Microsoft's Hyver-V, you can virtualize your network switches as well, saving rack space, providing virtual LANs and managing your networking infrastructure much more economically, providing redundancy at a much lesser cost using all virtual cost. Virtual switches and routers are easy on management and provide great performance monitoring and reporting capabilities.
