High availability architecture

The Dell Wyse Management Suite architecture consists of Windows Server 2012 R2/2016/2019 with failover cluster enabled. The

Windows cluster contains a main computer that supports other applications and ensures minimum downtime by harnessing the redundant.

This is used for application failover for Tomcat, Memcache, MQTT services. MongoDB database cluster helps in the event of primary

database failure the secondary database will take over. MySQL InnoDB database cluster has an inbuilt database clustering mechanism and

secondary database will take over in case of primary read write database fail. Linux Server with HA Proxy is a load balancer and high

availability server for EMSDK (Teradici) server. Local repository is created as part of the shared path that contains the applications,

images, packages, and will not be part of the cluster set up.

NOTE: The high availability system requirements may change depending on the infrastructure at your work site.
