What networking concepts should DevOps engineers learn first?
DevOps engineers should first master networking concepts that directly affect production reliability: IP addressing, DNS, load balancing, TLS, routing, and basic VPC design. These fundamentals explain most real-world deployment and outage issues.
Practical guidance
- Start with DNS, HTTP(S), TLS, and load balancer behavior before advanced overlays.
- Learn VPC fundamentals: subnets, route tables, security groups, and network ACLs.
- Understand service-to-service communication, service discovery, and failure modes.
- Practice troubleshooting using packet flow and request path tracing.
