The traditional mindset around disaster recovery has been that it is too expensive for anyone other than the large enterprise.  DR meant a second data center with 2x the number of servers and infrastructure and 2x the management complexity (every change had to be replicated at two locations). We’ve all talked about this here before. [...] Read More

This eliminates the 1:1 mapping for high availability (for every active server there is a corresponding active/passive server) and therefore creates N+1 high availability. That’s great but what [...] Read More
