As organizations initiate virtualization projects in their operating environments, common edge services such as Domain Name System (DNS) and Dynamic Host Configuration Protocol (DHCP) make a perfect candidate for virtualization. Because of the high costs and inflexibilities associated with traditional, hardware-based DNS and IP addressing computing appliances, most organizations have implemented existing D-services (DNS, DHCP) by utilizing unsupported open source software (BIND, DHCPD) or generic Microsoft server products (Microsoft AD) on industry standard servers. These home-grown servers typically utilize a very low percentage of their CPU. They are also prone to vulnerabilities, unnecessarily tedious to manage, and require on-going maintenance. Virtualization is an excellent way to streamline these inefficiencies.
