Chapter7Clustering web components
This section discusses the clustering of multiple web components which
includes Apache web servers and the Tomcat-based Borland web containers.
In a typical deployment scenario, you can use multiple Borland Partitions to
work together in providing a scalable n-tier solution.
Each Borland Partition can have the same or different services. Depending on
your clustering scheme, these services can be turned off or on. In any case,
leveraging these resources together or clustering, makes deployment of your
web application more efficient. Clustering of the web components involves
session management, load balancing and fault tolerance (failover).
Stateless and stateful connection services
Interaction between the client and server involves two types of services:
stateless and stateful. A stateless service does not maintain a state between
the client and the server. There is no "conversation" between the server and
the client while processing a client request. In a stateful service, the client and
server maintains a dialog of information.
For information about the location of the Borland web container configuration
files, go to Chapter 4, “Web components”.
