The Arellia Management Server (AMS) allows organisations organizations to manage all of their endpoints from a single web console.
In order to To facilitate this centralised centralized management, the AMS has been designed with High Availability and Load Balancing features, so that there is no single point of failure within the product.
There are two components that make up the AMS:
- Web front end
- SQL database back end
Web front end
Using Microsoft Internet Information Services the (IIS) the web front end provides the communication channel between the server and clients and the web console that allows users to administer the system over HTTP and/or HTTPS.
A single AMS installation can have one more than one more more web front end servers. The benefits of having multiple front ends are:
...
The client/server communication channel is encrypted using SSL which will require that all nodes in the web front end cluster have a SSL certificate installed. Nodes within the cluster do not need to share the same certificate, and optionally the load balancer can terminate the SSL connections on its external interface and communicate with the web front end nodes using normal HTTP thereby freeing up CPU resources.
SQL database back end
AMS supports the use of SQL server clusters for High Availability scenarios. We support all cluster types including stretch clusters, however the latency between the web front end and each SQL cluster node must be no greater than 30 ms. AMS also supports SQL Server fail over cluster configurations. Note that an active/active configuration does not provide improved performance, just high availability.
