Total Uptime Cloud Load Balancer

Pros: It simply works. After a modest learning curve, unless you need to make changes, it is set-and-forget.

Cons: Nothing really not to "like." With any program of this complexity, there is a learning curve. Staff is responsive, knowledgeable, and helpful.

Overall: We have 12 failover pools with monitoring for various A records, and WAN addresses registered for two ISP circuits, with a primary and secondary for failover.

I took registered domains and make Total Uptime the authoritative DNS for these domains. You tell it what IP addresses to monitor, and which to use for primary and secondary failover.

Failover triggers are highly customizable as to when to failover and when to failback. In our case we use simple ping monitoring, which is sufficient for our purposes.

We are alerted of every failover and failback.

Pros: Really impressive platform, solid load balancer and crazy good support. I first used Total Uptime a couple years ago for my first project which was an ADFS cluster deployed on three continents. This was exactly what we needed to distribute traffic to the closest server and automatically reroute traffic if a server went offline or was taken down for updates. This service is 100% perfect for this application.

Cons: Not really a con, but there are a LOT of features which makes the product somewhat complex.

Overall: Fantastic. Initially when we logged into the panel it was a little overwhelming because there were so many knobs to turn. But the support was incredible and literally had us up and running in a few minutes. Now after using it for a while I find it quite easy to use and have deployed it for a couple other projects since then.
