Virtual Private Solutions And Business Networking
Hello,How is redundancy improved? If you have 3 separate virtual servers running on a host and each of them serves a specific business function (say, one runs a web server, the other a DB server, etc..), and if the physical box fails, then all 3 VMs are going to go down, correct? So in your example, if 20 to 60 VMs are running on one physical host, then that becomes a single point of failure…I fail to grasp what the advantage of virtualization is. One physical box has a certain computing power. Now installing 3 VMs on that physical server would mean the computing power needs to be shared three ways, is that not correct? So essentially you are distributing the computing resources. What if the services on the one of the VMs need more computing power than the others? How does virtualization improve anything?Thanks
I am working on a project that deals with security and am very interested in virtual servers. Is this a viable choice? Should I spread the VMs across the nation in the case of a natural or other disaster for built in mitigation? What can be done if one of the main non-virtual servers goes down?
