FIXEdge servers are often used in business critical systems for interchange of financial information between clients and providers. Usually such systems require high-availability because downtime leads to significant money losses. Besides being high-load systems they often require good scalability that is a problem for non-cluster systems. Having several standalone FIXedge servers may be a reasonable approach in some cases but it has some significant drawbacks - client sessions must be distributed manually, it may be hard to manage configuration of several FIXEdge nodes, system will not be failure tolerant. To meet these needs Load-Balancing Cluster Solution is provided to:
Cluster is able to run several instances of some critical services such as Configuration Service, Scheduler Service, Cluster Coordination Service to increase availability. A brief description of cluster components and logical diagram are available here.
Deployment of cluster is described here.
