Sun Java Communications Suite 5 Deployment Planning Guide

Instant Messaging Sizing Strategy Overview

When you design your deployment, you must decide how to configure your Instant Messaging server to provide optimum performance, scalability, and reliability.

Sizing is an important part of the design effort. The sizing process enables you to identify what hardware and software resources are needed so that you can deliver your desired level of service or response time according to the estimated workload that your Instant Messaging server users generate. Sizing is an iterative effort.

Because each deployment has its own set of unique features, this chapter will not provide detailed Instant Messaging sizing information for your specific site. Also, this chapter will not provide sizing information for servers with which Instant Messaging interoperates, such as LDAP, SMTP, and so on. Rather, this chapter explains what you need to consider when you architect your sizing plan. In addition, you’ll find general guidelines for Instant Messaging components you can modify to suit your site’s needs. Work with your Sun technical representative for your deployment hardware and software needs.
