AWS Basic – Network 101

Here are the AWS Networking knowledges that are fundamental for cloud computing.

Region: (e.g. us-east-1)

AWS has the concept of a Region, which is a physical location around the world where we cluster data centers.

Each AWS Region is designed to be isolated from the other AWS Regions. This design achieves the greatest possible fault tolerance and stability.

VPC:

The Amazon Virtual Private Cloud (Amazon VPC) service lets you provision a private, isolated section of the AWS Cloud where you can launch AWS services and other resources in a virtual network that you define.

Availability Zone: (e.g: us-east-1a)

An Availability Zone (AZ) is one or more discrete data centers with redundant power, networking, and connectivity in an AWS Region. AZ’s give customers the ability to operate production applications and databases that are more highly available, fault tolerant, and scalable than would be possible from a single data center.

Subnet:

Separate subnets for unique routing requirements. AWS recommends using public subnets for external-facing resources and private subnets for internal resources. For each Availability Zone, this Quick Start provisions one public subnet and one private subnet by default.

Internet Gateway:

An internet gateway is an access point through which your resources can access the internet and be accessed from the internet.

NAT Gateway:

A NAT gateway can route outgoing traffic from private subnets to the internet.

Route 53:

Amazon Route 53 is the DNS available for your AWS resources.
