Chapter 1: Networking Fundamentals
Namaskar mitranno! Before we launch any server on the cloud, let's first understand how computers find and talk to each other. Every cloud concept — security groups, VPCs, subnets, Elastic IPs, load balancers — is built on basic networking. In my sessions, students often want to jump straight to EC2, but I always say: networking first, cloud later. If you understand this chapter well, AWS networking becomes ekdum simple.
