It's all very well agreeing SLAs for SQL services in terms of nines, but how do you ever translate any SLA (i.e. 99.9% or 99.99%) into 'which SQL architecture can actually achieve this'?If I have 3 VMs in a SQL AG, one in DR, all atop of some storage snapshot tech, in VMWare clusters, what SLA is that actually fulfilling?Interested to have your thoughts.
