Objective

1. Generate load on the system for a given number of users
2. Monitor the system's resource utilization using Grafana
   • This will give us a benchmark of the expected "load" on the cluster
3. Take user feedback regarding general usability of the system under the desired load conditions
   • This will let us know if user performance has degraded due to any stress on the system
4. Take note of how any node additions / removals affect resource constraint, and to what degree
   • If the system's resources become constrained, add a node to the cluster alleviating the resource constraint
   • If the system is far over-saturated with resources, remove a node from the cluster to simulate a downed node
