Networking for DevOps

🌐 Networking for DevOps

Networking is a core skill for DevOps engineers — without it, automation and cloud systems break.

Key areas to focus on:

• OSI & TCP/IP models

• IP addressing & CIDR (subnetting)

• DNS & service discovery

• HTTP / HTTPS & APIs

• Ports & protocols (TCP vs UDP)

• Firewalls & security groups

• Load balancers & reverse proxies

• NAT, VPN & secure connectivity

• Cloud networking (VPC / VNet, routing)

In DevOps, networking is hands-on troubleshooting, not just theory.

Understanding networking helps you debug faster, deploy safer, and scale systems reliably 🚀
