Understanding virtualization technologies



you know virtualization is the terms used in multiple places and I think computer science traditionally is virtual memory there's you know virtual file system storage etc they you know nowadays virtualization is usually used to describe essentially virtual computer virtual system and I think depending on where in the spectrum of the toolset you're using that's everything from a very one to one you know you you create a computer with two CPUs and four gigs of RAM and storage or at the kind of cloud you know kind of less tightly organ or organ straighter but kind of less tightly coupled idea it's you know this idea of memory resources CPU resources and storage resources and they're just kind of arbitrarily connected because you can out not only share resources and people are certainly talking about consolidation these sorts of things i really think that it's just the next step is that it allows you to abstract at a different level so you know what let's say previously required power switches and some fancy physical system management you can now do on the software layer and i think when you start to you know abstract that away I mean you really start to get a lot more powerful paradigms to be used by by customers today when people talk about virtualization is you know now talking about cloud and cloud is I think the first obvious example of you know abstracting away physical systems to generic resources I think you've seen you know the previous kind of kind of compute model would have been HBC is another good example of people trying to achieve that but you know there's a lot of constraints with respect to Hardware bring up the kernel you're using or the OS and it just really got sticky you know virtualization essentially wipes all that away because we're now presenting the system you see we you know intercept GD is and windows are actually an X do the same thing of do local rendering you now can have a really high performance virtual graphics card as well even on the same system and so that just allows you portability in a way that you didn't previously have so what's happening is we can we can really leverage those hardware functions very easily we've I think Linux has always been a great and kind of first stop for hardware n ableman so from platforms standpoint you know it's not surprisingly linux vendor is in the lead position to provide the lead hypervisor platform kind of components so i think the people really are starting to you know you don't have to explain open source them anymore you don't explain linux anymore we've seen that evolved over the last few years and i think people really understand that open standards are important open tooling is important etc you know I can tell when you go talk to a customer you don't have to explain the value they just get it and I think we're you know better poison anybody to to win in that space
