            <title>[DOCS-8530] We need to better advise customers on how to deploy mongos</title>
                <link>https://jira.mongodb.org/browse/DOCS-8530</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;We should advise decide where to deploy &lt;tt&gt;mongos&lt;/tt&gt; and how many to deploy. &lt;/p&gt;

&lt;p&gt;Customers are being advised in the &lt;a href=&quot;https://docs.mongodb.com/manual/core/sharded-cluster-query-router/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;mongos&lt;/tt&gt; documentation&lt;/a&gt;:&lt;/p&gt;

&lt;blockquote&gt;&lt;p&gt;The most common practice is to run mongos instances on the same systems as your application servers, but you can maintain mongos instances on the shards or on other dedicated resources.&lt;/p&gt;&lt;/blockquote&gt;

&lt;p&gt;However, if the customer has hundreds of application servers and/or are deploying &lt;tt&gt;mongos&lt;/tt&gt; with their application server, we run into situations where there are too many &lt;tt&gt;mongos&lt;/tt&gt; database servers running (and thereby causing problems) and/or there are thousands of documents in the config database related to &lt;tt&gt;mongos&lt;/tt&gt;. &lt;/p&gt;</description>
