Network Infrastructure Services:
• Security services
• Proxy server
• Web caching server
• Network load-balancing server
Network Infrastructure Services include:
•
Security services: Firewall services, public key processing for secure transactions, and any other applications that
provide network security. These services typically run on one or more 1U servers that are positioned between the
users (both internal and external) and sensitive data on a secure network.
•
Proxy services and Web caching server: One or more servers located close to the edge of the secure network, but
behind the firewall, to act as an intermediary between Web clients and Web server and/or cache commonly accessed
Web objects (pages, graphics and sound). Proxy services provide a level of security and user control. Caching
services typically improve the response times of commonly used Web sites, since the objects can be loaded from the
cache over the local area network instead of pulling the objects from a remote site over a slower wide area network
connection. These services typically run on a set of clustered 1U servers.
•
Network load-balancing server: A specialized application that balances access requests between a set of servers
that provide identical services. This is typically used with Web services but can be used for any number of other
applications. This type of service can be provided by a dedicated application running on a single server that collects
all in-bound requests and distributes these requests evenly to a set of servers, or it can be an application such as
Microsoft Network Load Balancing* that is loaded on a set of servers within a defined load-balanced cluster. Either
scenario is typically implemented using 1U servers.
