Hi, we want to offer services on 4 servers. These services should be high available. All services will have very low usage.
1) The first plan was to use 8 servers and create 4 HA-clusters. But 8 servers doing very little is waste of money. So the next plan was: 2) Use 5 servers, build one big cluster and distribute the services in such a way, that not two services run on the same machine. One spare is left with this architecture. 3) Next plan: Use only two physical servers, create 8 virtual servers, build one cluster on the physical machines and have heartbeat look for the virtual machines. But the problem with this setup is that monitoring of the virtual machines does not look, if the applications on these virtual machines do really run. 4) Next plan: Setup as before, 2 cluster between the two physical machines, 4 clusters between the 8 virtual machines. Monitoring on the cluster of the physical machines looks for the health of the virtual machines and monitoring in the virtual clusters look for the health of the applications. My question: What is really the best solution? Isn't solution 4) far too complex? What is your oppinion. Thanks for any answer.
