Re: [PLUG] small business server virtualization?


I generally virtualize as many services as possible for clients as long as it makes sense.  Windows runs just fine on KVM and my oldest deployment is a Windows 2000 application server (though I think I have it running on Virtualbox on Linux right now).  The forward hardware refresh cycle is greatly reduced financially.  That is always welcome as long as services have the same or better performance.  KVM works just fine but whatever poison you pick, your users are really the ones who will let you know how well things are working.

Virtualizing **every** individual service might a lot of work for little overall gain but you also don't have to deploy everything at once.  You can get there slowly.

Subject: [PLUG] small business server virtualization?

Does the overhead of virtualization make sense for small organizations? 
We have various applications running on two physical servers and run 
into the situation where two or more applications need Apache so 
configuration of one potentially interferes with configuration of 
another.  And likewise, upgrades or maintenance of one application 
require the server to be taken offline for a while, cutting off access 
to others.
Can it make sense to virtualize so that each application has its own OS 
instance, which can be powered on and off, upgraded, etc. independently, 
for a small business?

It looks like VMWare's vSphere Essentials would run us $500 or so a 
year, is it worth it to pay that?  What's the best alternative as a 
bare-metal hypervisor, Xen?  KVM is a no-go because we have to be able 
to do Windows servers, too.
