For many systems such as the web-based e-commerce systems a 99.99% availability
would be sufficient but for many other systems like those used for life
saving or defence purposes a higher-level of availability would be required.
In a ServiceMix cluster, SEs and BCs can still continue to run in a different
server instance when one of the server instances fails. As you can deploy the
application components to multiple server instances in the cluster, if a server
instance on which a component is running fails, another server instance on
which that component is deployed can continue the processing thus increasing
the overall system availability.
Load balancing: Load balancing is the even distribution of jobs and processes
across the computing and networking resources in your ServiceMix cluster.
For load balancing to occur, there must be multiple copies of a ServiceMix
component that can serve a particular consumer. Information about the
location and operational status of all the ServiceMix components must be
available centrally and across.
