Using appliance servers
This technique applies to the edge servers, the Web presentation server, the directory and security servers, the network, and the Internet firewall. The goal is to improve the efficiency of a specific component by using a special-purpose machine to perform the required action. These machines tend to be dedicated machines that are very fast and optimized for a specific function. Examples are network appliances and routers with cache.
Some issues to consider regarding special machines are the sufficiency and stability of the functions and the potential benefits in relation to the added complexity and manageability challenges. It is worth noting, however, that devices of the newer generation are increasingly easy to deploy and manage; some are even self-managed.
