title: WSO2 api manager gateway cluster configuration
body: <p>While attempting to create a cluster for my API Manager I'm confused on some of the documentation.
  Here is the architecture:
  MS SQL Server as the database.
  Single node VM that runs both the Publisher and the Store.
  2 additional nodes that run the gateway and key manager.</p>
  
  <p>The documentation says to install the different components by copying the same install over and over...but that doesn't make sense to me.  I want the publisher and store to run together (just like a stand alone), and I want the gateway and key manager to run together (again, like a stand alone), but be clustered for throughput.</p>
  
  <p>When I use this guide:
  <a href="http://docs.wso2.org/display/CLUSTER420/Clustering+API+Manager" rel="nofollow">http://docs.wso2.org/display/CLUSTER420/Clustering+API+Manager</a></p>
  
  <p>It indicates in step 10a-b that we should update:  to point to WSO2REG_DB.  However, this configuration item doesn't even exist.  It also has additional configuration that does exist...</p>
  
  <pre><code>&lt;remoteInstance url="https://publisher.apim-wso2.com"&gt;    
  &lt;id&gt;gov&lt;/id&gt;   &lt;dbConfig&gt;govregistry&lt;/dbConfig&gt;   &lt;readOnly&gt;false&lt;/readOnly&gt;           
  &lt;enableCache&gt;true&lt;/enableCache&gt;   &lt;registryRoot&gt;/&lt;/registryRoot&gt;&lt;/remoteInstance&gt;
  &lt;mount path="/_system/governance" overwrite="true"&gt;   &lt;instanceId&gt;gov&lt;/instanceId&gt;
  &lt;targetPath&gt;/_system/governance&lt;/targetPath&gt;&lt;/mount&gt; 
  </code></pre>
  
  <p>and again for the store (except the remoteInstance url is slightly different).
  Can I simply point the default config for the file registry.xml to point to WSO2REG_DB and leave the remote instance configuration the default stand alone for my publisher/store node?</p>
