<div id="body0000001532790844"><div class="section" id="mrs_01_24159__section15452101742314"><h4 class="sectiontitle">Scenario</h4><p id="mrs_01_24159__p162451922112315">IoTDB uses the multi-replica deployment architecture to implement cluster high availability. Each region (DataRegion and SchemaRegion) has three replicas by default. You can also configure more replicas. If a node is faulty, replicas on other nodes of the region replica can take over services from the faulty node, ensuring service continuity and improving cluster stability.</p>
