# Calico CNI
Current top-level still contains the deprecated Canal implementation.
Removed once new AWS config is tested and rolled out to all existing clusters.
## AWS
Calico is setup based on the upstream calico-vxlan config from
`https://docs.projectcalico.org/v3.15/manifests/calico-vxlan.yaml`
Changes:
- VxLAN set to Always to not expose cluster communication to VPC
-> EC2 SecurityGroups still apply and only need to allow UDP 4789 for VxLAN traffic
-> No need to disable source/destination check on EC2 instances
-> Prepared for optional WireGuard encryption for all inter node traffic
- MTU set to 8941
- Removed migration init-container
- Disable BGB and BIRD health checks
- Set FELIX log level to warning
- Enable Prometheus metrics
## Prometheus
See: https://grafana.com/grafana/dashboards/12175
