[Verse 1]
TCP IP builds the internet foundation
Four layers working in coordination
DNS translates the names we know
To IP addresses where packets go
HTTP two streams data fast
But QUIC makes three even more vast
[Chorus]
Network layers, protocols and gateways
VPCs and subnets showing us the pathways
CDN edges, APIs secure
Zero trust model keeps attacks from the door
TCP DNS HTTP TLS
VPC subnet gateway success
[Verse 2]
Virtual private clouds contain your servers
Subnets split the traffic like preservers
Security groups act like a firewall
NACLs protect the network overall
Peering connects the clouds together
Transit gateways handle any weather
[Chorus]
Network layers, protocols and gateways
VPCs and subnets showing us the pathways
CDN edges, APIs secure
Zero trust model keeps attacks from the door
TCP DNS HTTP TLS
VPC subnet gateway success
[Verse 3]
CloudFront Cloudflare Fastly serve content near
Edge computing brings the data here
Kong and AWS Gateway guard the door
Rate limiting stops the traffic war
Authentication checks who gets inside
TLS encrypts what packets hide
[Bridge]
Never trust always verify the source
Identity aware proxies stay the course
WireGuard tunnels through the VPN line
SD WAN connects sites by design
DDoS attacks try to bring you down
But protection strategies hold the crown
[Chorus]
Network layers, protocols and gateways
VPCs and subnets showing us the pathways
CDN edges, APIs secure
Zero trust model keeps attacks from the door
TCP DNS HTTP TLS
VPC subnet gateway success
[Outro]
BeyondCorp model shows the modern way
Phoenix Project guides us every day
From hybrid clouds to multi site
Network knowledge makes it right
