Hello,
We are a company providing Servers/Infrastructure administration. Some of our customers have similar projects. For assuring maximum uptime, we use a distributed monitoring system. Our engineers work in shifts, 24/7, so there are virtually no problems that we would not observe and fix pro-actively.
Among other things, we monitor the cluster status too.
The cost of our services would be:
90$ - setup
160$/month - monitoring (20$ * 3) and 6 hours of technical support for 3 servers.
Sincerely,
--
