Seeking advice if its preferable and recommended with 4 available server resources to have them stood up as a single Cluster distributed between 2 Data Centres to achieve the most optimal High Availability and Resiliency as opposed to having them split into 2 Cluster of 2 Nodes each, one for each DC.
Would either setup options be valid?
2 x DC
4 x Servers
Only Data Service utilised
Appreciate any advice or information.
