In this episode you will learn:
- A VPC is your private, isolated network in AWS, and subnets are used to partition it across Availability Zones for high availability.
- A subnet becomes public by having a route in its route table that points to an Internet Gateway (IGW), enabling two-way internet communication.
- Private subnets achieve secure, outbound-only internet access for tasks like software updates by using a NAT Gateway that resides in a public subnet.
- VPC Peering creates a direct, one-to-one, non-transitive connection between two VPCs, meaning you cannot chain connections through a central VPC.
- AWS Transit Gateway acts as a scalable, central hub to connect many VPCs and on-premises networks, overcoming the limitations of VPC Peering.
