"Virtualization on Linux is nothing new. It's been
around now more than 10 years and has advanced considerably but
that doesn't mean it's simple. To the contrary, shops have a
dizzying array of virtualization options to manage workloads and
storage, and to reduce complexity, costs and energy usage. There's
no question about whether to deploy virtualization; the real
question is what virtualization solutions to look at and what
workloads to virtualize. We'll help cut through the complexity and
help set the options straight.
"Virtualization isn't always the answer, of course. Some
workloads work best on physical servers without any abstraction.
But there's quite a few advantages to using virtualization in the
server room. In this feature, the first of a four-part series on
virtualization, we will begin with an overview of the
virtualization solutions on Linux. You can look forward to more
details on standard virtualization strategies, virtual appliances,
cloud computing, and more, in the weeks ahead.
"What's in Virtualization for You
"Virtualization isn't a hard sell these days. First and
foremost, you have increased server utilization and lower energy
costs by using virtualization to maximize the number of workloads
running per server. In the bad old days of computing, Linux running
on commodity x86 hardware tended to use only a fraction of the
available computing power of a server. By using virtualization, you
can ensure that the hardware is running a reasonable workload and
save power by consolidating several workloads on one system."
