Clearly, there’s a new trend emerging with lots of options, but also many challenges that could cost big money to reverse. How does virtualization address these challenges and allow a seamless transition to a cloud strategy, either on- or off-premise?
As mentioned above the key requirements you should demand from your cloud providers are: broad application support without lock-in, ease in mobility of environments, broad choice of locations (internal or external), and innovation that drives simplified federation of on- and off-premise clouds. Additionally, as an enterprise you’ll want to look for innovation in building the internal (private) cloud to evolve your ability to offer dynamic services.
As noted, virtualization is the key. Most companies’ first step on the virtualization path is to consolidate their servers, using virtualization to run multiple applications on each server instead of just one, increasing the utilization rate of (and getting more value from) every server and, thus, dramatically reducing the number of servers they need to buy, rack, power, cool, and manage.
Having consolidated servers, you realize that not only have you substantially cut the capital and operating costs ofyour server environments, but as a result the entire datacenter has become far more flexible. Along the way, you may have started to think about and to use IT resources – including servers, storage, networks, desktops, and applications – not as isolated silos that must be managed individually but as pools of resources that can be managed in the aggregate.
This means that you can now move resources around at will across the network, from server to server, datacenter to datacenter, and even out into the cloud, to balance loads and use compute capacity more efficiently across the entire global IT environment.
In other words, users are able to look at the compute power as a centralized resource that they can now allocate to business units on demand, while still maintaining control and operational excellence.
Leveraging virtualization to better serve users gives your organization the obvious lower TCO, but also allows for accountability of usage, simplifies and meets the needs of on-demand infrastructure requests, and allows for your ability to serve, control and manage SLAs.
Hence, virtualization has played and will continue to play a huge role in cloud computing. It is the technology that has allowed service providers to deliver lower-cost hosting environments to businesses of all sizes today. Just as virtualization enabled you to consolidate your servers and do more with less hardware, it also lets you support more users per piece of hardware, and deliver applications – and the servers on which they run – faster to those users.
