Subject:Suggestions on db server configuration - Replication & load balancing
or Clustering??
View as plain text  
I need to come up with a high availability, high performance MySQL 
server setup. I have two database servers half way across the country 
from one another being replicated through a VPN. These db servers serve 
two very busy web sites with multiple applications accessing the db. 
During busy times we are seeing 1200 to 2000 QPS. For good reason our 
database servers have high load averages during peek times. I have been 
looking at MySQL clustering, but due to the fact that our database is 
rather large the in memory only restriction will make it unfeasible. The 
other option is load balancing and replication. My problem with this 
setup is that there will be too many points of failure since there can 
only be one master for each slave. Not to mention the lag that may be 
introduced since there would be multiple servers at each location. It is 
crucial to the operation of the sites that all of the servers stay in 
sync at all times.

Does anyone have any suggestions?
