AWS consists of interconnected Regions, each having multiple Availability Zones (AZ). AZ is an isolated area that consists of one or more physical Datacenters. Virtual Private Cloud (VPC) within a Region is your Virtual Datacenter. AZ-specific subnets in your VPC are either Public with Internet GW or Private with or without NAT GW. You can build a VPN between your on-prem DC to AWS VPC using a Virtual Private GW, or Transit GW. Using AWS Direct Connect, you can establish a dedicated connection from on-prem to VPC. You can Inter-connect VPCs with VPC Peering, Private Link, or Transit GW. NACL and Network FW protect your Subnets while Security Groups guard your EC2 instances. This book is your guide to AWS Networking.
