What is virtualization?
Virtualization is a technology that enables a single server to act as many. Solutions such as VMware’s Virtual Infrastructure work by, in effect, converting hardware into software. This is achieved by the creation of virtual machines (VMs) which VMware describe as, “Tightly isolated software containers that can run their own operating systems and applications as if they were physical computers. A VM behaves exactly like a physical computer and contains it own virtual (software-based) CPU, RAM, hard disk and network interface card (NIC).” In other words, a VM is simply a computer that has been converted entirely into software and packaged into a single file.
The fact that each VM has its own virtual CPU, NIC, etc., means that it can be run on practically any hardware - even hardware on which other VMs are running. Accordingly, virtualization breaks IT’sone-application per-server model by enabling multiple heterogeneous operating systems to be simultaneously run on the same physical server.
Customer testimonials
“We moved to WebTitan 6 months ago which saved us 50% in license fees. Our business was delighted about the saving, and as an Administrator I knew that I would enjoy the same flexibility, scalability and stability that we experience with SpamTitan. We enjoy the fact that WebTitan runs on a lightweight OS base. We require no OS license (Windows) like we did with previous solutions. The additional virus protection built into WebTitan is a great feature not available in competitor products. The native LDAP support is great – we can integrate into Active Directory and Novell Directory Services. I believe that we added value to our organization by replacing our existing solution with WebTitan at 50% of the cost.”
