Replicated System

Classification Key : Exterior Security, Tampering


Transactional systems are often susceptible to outages of communication links, communication elements or other system elements. It is important to assure availability of transactional services in the midst of such failures. How can this be done?


Replicate services at multiple points in the network and during failure replace the failed service with an available service. Perform load-balancing based on some workload scheduling mechanism by a workload management proxy.
