Comparison of Standard and High Availability Modes

NOT AVAILABLE IN SAAS High Availability mode allows you to configure and deploy Ekran System in such a way that it can operate with multiple Application Server instances installed on different nodes in a Microsoft failover cluster. This provides for load balancing of data sent to the Application Servers by Ekran Clients to optimize performance, and ensures data integrity in case any of the instances go offline for any reason by using a backup Application Server for disaster recovery.
