Application Switching Solutions
Application switches provide maximum availability to applications by intelligently distributing traffic among all available servers, and dynamically monitoring the ability of servers and applications running on the servers to deliver optimal performance. Using customizable health checks at various levels of granularity like host, port, application and transaction levels, load balancers transparently react in real time to increases and decreases in available server capacity by redistributing client traffic. Failures of servers and applications running on the servers do not cause disruption to the end clients. The failed resources are simply set aside until they come back online, and client connections are re-directed to other available servers. These switches can be deployed in multiple high-availability modes with stateful session synchronization and failover to preserve client connections during catastrophic failures. Applications are transparent to the presence and failures of load balancers, and function uninterrupted.
