<div id="body1536546371708"><p id="gaussdb_01_0001__p775320616018">Understanding the following concepts helps you better use <span id="gaussdb_01_0001__text1066696792">TaurusDB</span>:</p>
<ul id="gaussdb_01_0001__ul117531461402"><li id="gaussdb_01_0001__li18753464017">Cluster: <span id="gaussdb_01_0001__text2086683424">TaurusDB</span> uses the cluster architecture, with one primary node and multiple read replicas.</li><li id="gaussdb_01_0001__li1053914380309">Region: A region is a physical data center. Generally, <span id="gaussdb_01_0001__text2143731963">TaurusDB</span> instances and ECSs must be located in the same region for high access performance.</li><li id="gaussdb_01_0001__li6753961019">Availability zone (AZ): An AZ contains one or multiple physical data centers. Each AZ has independent cooling, fire extinguishing, moisture-proof, and electricity facilities. Within an AZ, computing, network, storage, and other resources are logically divided into multiple instances. An AZ is a geographic location with independent power supply and network facilities in a region.<p id="gaussdb_01_0001__p1166161869"><a name="gaussdb_01_0001__li6753961019"></a><a name="li6753961019"></a>AZs are physically isolated but interconnected over an intranet. Each AZ provides cost-effective and low-latency network connections that are unaffected by faults that may occur in other AZs. As a result, provisioning <span id="gaussdb_01_0001__text261109528">TaurusDB</span> instances in separate AZs protects your applications against local faults that occur in a single location. AZs within the same region have no functional differences. </p>
</li><li id="gaussdb_01_0001__li197535613015">Instance class: resource configuration of each node, for example, 16 vCPUs and 64 GB.</li></ul>
