Virtualization: The "New" Kid on the Block
The typical data center hosts a large number of servers. In these security-conscious days, the data center is typically the preferred location for enterprise-critical machines, data, and server software. The problem is that many data centers are running out of both power and physical space. Virtualization provides a neat solution because it allows you to host more than one given operating system instance on one physical machine. Figure 1 illustrates the basic idea.
Figure 1 Virtualized Linux servers.
Figure 1 show two Linux servers being hosted on a single platform. The latter contains two Linux virtual machines, each of which continues to offer services to its user population. So virtualization allows you to consolidate the number of servers in your network. Provided that the virtual machine host has sufficient power, the users of the virtual machines should see no substantial drop in quality of service. However, the data center savings can be substantial.
Okay, that’s some background out of the way. Now let’s get started on learning about virtualization, using the excellent products available from VMware.
