Ended: September 12, 2019

Objectives:

This print continued the theme of system scalability.  We looked at how the system degrades when resources are constrained.  

Results:

The team invested significant time in understanding how Kubernetes can be configured to impact how the system degrades under resource over-runs.  They examined both limitations and workarounds and a lot of this work will bleed over to the next sprint.  

More RCE Data collection and analysis was done during this sprint to help shape what the first production environment will look like.

The team was short-staffed throughout the sprint with operations work requiring input from multiple team members.
