Chapter 12. Understanding clustering

A single JBoss server can handle several hundred concurrent requests; but, if your application has to scale to support multiple thousands of concurrent requests or multiple millions of requests a day, then a single application server probably won’t do the trick. JBoss enables you to simultaneously run your application on multiple application servers. Requests going to your application can then be balanced across these servers, and your application can also withstand individual server failures. This deployment architecture allows you to achieve maximum scalability with minimal downtime. Clients need not know that their different requests may be handled by different servers.
