A cluster of two or more
Unwired Server nodes provides some degree of load balancing, but load
balancing can also be applied to both client connections and EIS connections, to improve
performance and efficiently use resources in the Unwired Server
cluster.
There are two load-balancing mechanisms you can use with the
Unwired Server cluster:
- Relay Server – an Sybase
software product that acts as a reverse proxy server for client devices communicating
with Unwired Server.
- Load balancer appliance – a third-party product, such as an L4
network switch, can be used for both client and EIS connections.
Note: You
cannot use Relay Server
on
EIS connections.
