„What makes Cumulus Linux so special?“

SLIDE 36

„What makes Cumulus Linux so special?“

Just a normal Linux Server based on Debian Linux
with lots of network interfaces
deployment and configuration
Troubleshooting: regular Linux environment
Monitoring/Logging: Prometheus/Elastic

SLIDE 37

„What makes Cumulus Linux so special?“ The special thing is: Our routers are nothing special anymore!
