• KubeAPI / REST API Layer

• Cloud Native CLI

• Telemetry Layer

Steps you can take now…

27

• Use CI/CD to adopt CI/CD • Get rid of the culture of “NO”• Use SnapRoute CN-NOS in your environment ;)• Define clear roles for each team• Find manual, repetitive changes – get rid of

them• Change maintenance window times • Networks are not sacred – don’t treat them as

such• Decrease time between upgrades – build the

muscle• Start small and build upon easy wins
