I hope you enjoyed the comparison and found it useful. We covered, to a great extent, the impact caused by virtualization and the changes it introduces. We started by clarifying that virtualization is a different technology compared to partitioning. We then explained that once a physical server is converted into a virtual machine, it takes on a very different form and has radically different properties. The changes range from the core property of the server itself to how we manage it. This, in turn, creates a ripple effect in the bigger picture. The entire data center changes once we virtualize it.

In the next chapter, we will cover capacity management in greater depth, as it is an area that is made more complex once you virtualize your data center.
