[Verse 1]
In defense networks, choices weigh like granite stones
Calico enforces policies, secures the zones
Cilium brings eBPF power, kernel-level sight
Multus multiplies interfaces, gets connections right
Selection criteria demand zero-trust foundations
Encrypted flows and audit trails across all stations
[Chorus]
CNI for connectivity, policies deny by default
Service mesh encrypts the mess, DNS resolves without fault
Layer four or layer seven, load balance the equation
Network depth protects the realm through careful orchestration
[Verse 2]
Network policies guard the gates with ingress rules
Egress flows must pass the test, no passage for the fools
Default-deny stance blocks all paths until approved
Whitelist every conversation, threats get swiftly removed
Zero-trust architecture starts with blocked connections
Add permissions grain by grain with surgical selections
[Chorus]
CNI for connectivity, policies deny by default
Service mesh encrypts the mess, DNS resolves without fault
Layer four or layer seven, load balance the equation
Network depth protects the realm through careful orchestration
[Bridge]
Istio heavyweight champion, full-featured and vast
Linkerd lightweight contender, simple and fast
mTLS certificates dancing, mutual authentication
Observability windows show traffic destination
[Verse 3]
CoreDNS resolver queries cluster names with grace
Cross-cluster lookups bridge the distributed space
Load balancers distribute weight through different schemes
Layer four routes packets swift, layer seven reads the streams
External facing, internal blazing, traffic patterns flow
Strategic placement optimizes how the data streams will go
[Outro]
Defense networks layer deep, security by design
Every packet, every socket, following the line
