Understanding Waveset Service Provider System Architecture

If the Waveset Service Provider feature is implemented, a fifth tier is required. This tier is called the Web tier and it consists of one or more web servers located in a DMZ. No Waveset components are installed in the web tier. Instead, the web servers in the DMZ support one or more application servers in the application tier by responding to web page requests. Adding one or more web servers to the web tier provides enhanced scalability, and placing the web servers in a DMZ provides better network security.

The Service Provider feature also requires an LDAP repository. This repository resides in the database tier. Because the LDAP repository can be a managed resource, the LDAP server can be understood as residing in the managed resource tier, as well.

In a service-provider-only implementation, a Waveset repository is required in addition to the LDAP repository in order to maintain configuration information, forms, rules, and other objects.
