PACEdge Software Services
PACEdge entails several communications, data processing, data storage, and visualization
applications that run on the Linux operating system. The following diagram provides insight into
which applications are best suited for which task. Please note that this is not a strict classification
as some applications overlap categories and can be used to achieve multiple tasks:

PACEdge was designed using Docker architecture, in which each application is running in its own
Docker container (Figure 6). Given that containers are designed to be easily replaceable they do
not retain an internal state between reboots unless specifically designed to do so. With PACEdge,
selected containers will map some of their data to data volumes on the host Linux system so that
Node-RED, Grafana, and database changes can be saved between Container restarts and updates.
