With “old school” IT infrastructure, you had a number of physical servers that served a variety of independent functions. These servers needed the security provided by hardware isolation, but that isolation came at the price of potentially underutilizing resources—which is both wasteful and costly. Along came virtualization, followed closely by cloud—technological leaps that enable companies to get more out of their IT investment:

Server virtualization enables multiple operating system installations to reside on the same server at the same time, but operate completely independently of one another. We call them “virtual servers” because they take what was previously one dedicated machine and turn it into many “virtual machines”. The ability to virtualize servers is one of the many advantages of Latisys' managed hosting and cloud services.

Latisys offers ultimate flexibility because we are “Hypervisor Agnostic”
|
At Latisys we understand that virtualization is not one-size-fits-all. Simply put, available hypervisors have different feature sets and some are better suited for different environments and workloads. We are proud to offer our customers choice. Not only do we support standard and enterprise versions of VMware vSphere, Latisys is the first Hosting and Cloud provider to certify Microsoft’s Hyper-V 2012 for our enterprise platform. And we’re here to help you “right-size” your environment—tailoring our solution to your specific requirements. Whatever hypervisor you choose, our expert virtualization engineers and flexible per-VM pricing model will make virtualization work for your business.
