<h1 class="topictitle1">Single Node Architecture</h1>
<div id="body1524735072535"><p id="dds_01_0025__p16172345183814">A single node instance, as its name suggests, contains only one node which can be accessed directly.</p>
<p id="dds_01_0025__p34524004112">As a supplement to the cluster and replica set architectures, the single-node architecture applies to R&amp;D, testing, and non-core data storage of enterprises. While not as robust as replica sets, the single node architecture can be a less expensive way to visualize O&amp;M and provide elastic scaling.</p>
