3.9 Cluster
Cluster Introduction: Cluster function uses servers of various grades as nodes, which
can solve the shortcomings of stand-alone computing capabilities, achieve high
computing speeds, and respond quickly, meet today's growing demand for information
services.
When the output is HTTP, the numbers of programs/services together with the number
of subscribers are limited by the capacity of a single server. To expand it, several
servers will be needed to be clustered. Such servers are Equilibrium/Load Balancing (BL)
Server, Cache Server, the Main Server itself and Backup Servers, and Storage when
needed.
The Equilibrium/Load Balancing (BL) Server handles the distribution and makes the load
balance. Cache Server saves the pages or other content locally. The Main Server is
where you manage the configuration and do the authorization of the subscribers.
The required number of each server needed will depend on the required number of
channels and number of subscribers.
An example of the interconnection of servers is shown below:
