A new enhancement to the Employease Network even allows employees to change their own data, easing staff demands. In sites deploying DISA, an array of high-volume application servers are deployed on the front end. This server array is made highly available through the use of intelligent IP load-balancing technology. With the DISA architecture, customers have the ability to affordably and flexibly scale as needed, while delivering performance and reliability for environments undergoing rapid growth. At the back end is an AlphaServer 4100 system running an Informix database.
Load balancing across many application servers also keeps availability high.
If any one server fails, the user wouldn't notice it. The DISA architecture also provides the utmost in security. At Employease, a firewall protects the application and database servers on the company's private network. Because of the Internet's cross-platform power, the Employease network operates across multiple platforms. And, inside the firewall, Tru64 UNIX and Windows NT work together seamlessly.
