A regional NoSQL cluster for emergency services must survive the loss of one datacenter site. What architecture theme does this requirement highlight?
Select an answer to reveal the explanation.
Short Explanation
If one datacenter goes dark, emergency data still has to live somewhere else. Multi-site NoSQL geo-distribution is that safety net. Do not park every replica on one lonely floor.
Full Explanation
Multi-datacenter and geo-distributed NoSQL deployments replicate or place data across sites for resilience. Emergency-services workloads need continuity when an entire facility fails. Single-rack or unreplicated designs create unacceptable regional single points of failure. Geo-distribution is therefore a recurring NoSQL architecture theme for civic disaster recovery.
