# Key definitions:
Region - the geographical location of your network
Availability Zone (AZ) - a data center containing your AWS resources
Virtual Private Cloud (VPC)- a logically isolated section of the AWS Cloud where you can launch AWS resources
Internet Gateway- enables access to the Internet for your VPC
Route Tables- determines where network traffic from your subnets are directed
NACLs- Network Access Control Lists. Act as a firewall at the subnet level
Security Groups- Act as firewall at the instance level
Subnets- a logical partition of an IP network into multiple, smaller network segments
# Availability Zones:
Availability Zones are the data centers where you launch your AWS resources into
Each AZs is associated with a specific region
# Key VPC Components:
A virtual private cloud (VPC) network is your own personal isolated section of the AWS cloud.
A route table contains a set of rules (called routes), that are used to determine where network traffic from your subnet or gateway is directed.
Internet Gateway- Allows you to grant internet access to resources inside of your VPC. But you also need a route table which routes the traffic from the VPC network out to the IGW
You can think of it as a door from your VPC outward.
