 Across Azure, *reliability* means maintaining resiliency and availability if there's a service outage or degradation. In Cognitive Search, reliability is achieved when you:
 
 + Configure a service to use multiple replicas, paired with availability zone support.
+
 + Deploy multiple search services across different geographic regions.
 
-All workloads are fully contained within a single service that runs in a single geographic region. Within a region, you can configure search to use multiple replicas that run in different availability zones.

-For business continuity and disaster recovery, you should develop a strategy that includes a cross-regional architecture, consisting of multiple search services having identical configuration and content. Your custom script or code provides the "fail over" mechanism to an alternate search service if one suddenly becomes unavailable.

-Although most customers use just one service, service redundancy might be necessary if operational requirements include the following:

 If you need two or more search services, creating them in different regions can meet application requirements for continuity and recovery, as well as faster response times for a global user base.
