In the previous chapters, we set up the View Horizon servers with basic DNS load balancing. DNS load balancing involves setting multiple host (A/AAAA) records for the DNS entry of the View connection servers and/or View Security servers. The DNS server with balancing provides multiple IP addresses per DNS entry to the View Horizon clients. The DNS server will randomly alternate between IP addresses served to the client to ensure multiple clients use different View Horizon servers. This provides basic load switching but doesn't account for balance. In practice (assuming identical hardware for the View servers), this will provide a load that is close to balanced but not quite. In the event of a View server failure, clients will timeout connecting to the failed server and try another IP. This method doesn't have a built-in method of monitoring uptime for services. In addition, DNS load balancing doesn't respond quickly to changes. If the TTL for the DNS record is long, it...
