We'll cover topics such
as getting your configuration up and running, developing test and operations scripts,
building custom telemetry screens, and give you some advice on participating in the future
development of COSMOS itself.</p>

<p>COSMOS is a suite of applications that can be used to control a set of embedded systems. These systems can be
anything from test equipment (power supplies, oscilloscopes, switched power strips, UPS devices, etc), to
development boards (Arduinos, Raspberry Pi, Beaglebone, etc), to satellites.</p>
<h3 class="anchor anchorWithStickyNavbar_LWe7" id="cosmos-architecture">COSMOS Architecture<a href="#cosmos-architecture" class="hash-link" aria-label="Direct link to COSMOS Architecture" title="Direct link to COSMOS Architecture"></a></h3>

<p>COSMOS 5 is a cloud native, containerized, microservice oriented command and control system. All the COSMOS microservices are docker containers which is why Docker is shown containing the entire COSMOS system. The green boxes on the left represent external embedded systems (Targets) which COSMOS connects to. The Redis data store contains the configuration for all the microservices, the current value table, as well as data streams containing decommutated data. The Minio data store contains plugins, targets, configuration data, text logs as well as binary logs of all the raw, decommutated, and reduced data. Users interact with COSMOS from a web browser which routes through the internal Traefik load balancer.</p>
<p>Keep reading for an in-depth discussion of each of the COSMOS Tools.</p>

<p>Throughout this guide there are a number of small-but-handy pieces of
information that can make using COSMOS easier, more interesting, and less
hazardous. Here's what to look out for.</p>
