<p dir="auto">Right now my XO instance controls 1 host with 2CPU/2 GB RAM. As my cluster grows, how should I scale it?</p>

<p dir="auto">"It depends" is the answer here <img src="https://xcp-ng.org/forum/assets/plugins/nodebb-plugin-emoji/emoji/android/1f642.png?v=1d3f495298e" class="not-responsive emoji emoji-android emoji--slightly_smiling_face" style="height:1.4em;width:auto;vertical-align:middle" title=":)" alt="🙂" /> Depends on:</p>
<ul>
<li>the number of concurrent users on your XO instance</li>
<li>the size/frequency/number of backup jobs you have</li>
<li>the number of hosts and VMs managed by XO</li>
</ul>
<p dir="auto">Frankly, for a small setup (less than 4/5 hosts) with one users and few backup jobs, the default 2vCPU/2GiB RAM is enough. Especially since we improved various process to happen in a dedicated worker <img src="https://xcp-ng.org/forum/assets/plugins/nodebb-plugin-emoji/emoji/android/1f642.png?v=1d3f495298e" class="not-responsive emoji emoji-android emoji--slightly_smiling_face" style="height:1.4em;width:auto;vertical-align:middle" title=":)" alt="🙂" /></p>
