[Verse 1]
In defense networks where secrets flow
CNI plugins are what you need to know
Calico brings security first in line
With policy enforcement by design
Cilium runs eBPF so fast and clean
Best performance that you've ever seen
While Multus lets you bridge multiple nets
Multi-homing without regrets
[Chorus]
Lock it down with policies tight
Ingress egress done just right
Default deny keeps threats outside
Service mesh for encrypted rides
DNS resolves both near and far
Load balancing where you are
Network deep dive, security pride
Defense infrastructure as your guide
[Verse 2]
Network policies set the rules
Ingress traffic through controlled pools
Egress filtering what goes out
Default deny removes all doubt
Start with nothing, add what's needed
Security boundaries well-heeded
Label selectors make it precise
Network segments rolled like dice
[Chorus]
Lock it down with policies tight
Ingress egress done just right
Default deny keeps threats outside
Service mesh for encrypted rides
DNS resolves both near and far
Load balancing where you are
Network deep dive, security pride
Defense infrastructure as your guide
[Verse 3]
Service mesh decides your fate
Istio's feature-rich and great
Linkerd keeps it simple, light
Both give mTLS done right
Mutual authentication flows
Observability that glows
Traffic management in between
Routing policies crystal clean
[Bridge]
CoreDNS resolves the names
Cluster zones and custom domains
Cross-cluster service discovery
Network paths for all to see
Layer four or layer seven
Load balancing straight from heaven
External facing, internal too
Traffic flows the way you choose
[Outro]
From CNI to service mesh
Network policies keep it fresh
DNS resolution, load balancing art
Defense networking, every part
Deep dive complete, security tight
Network infrastructure done right
