This project builds on my completion of Adrian Cantril’s course "AWS Certified Solutions Architect - Associate (SAA-C03)" and earning the "AWS Solutions Architect - Associate" certification.

Some of my implementations will be based off of Adrian's teachings

1. Set AWS profile after aws sso configure
   • export AWS_PROFILE=<sso_profile_name>

• 2 US (us-east-1, us-west-1)
• 1 Europe (Reserved)

2 Network Ranges per Region. Assume 4 Accounts

• 3 (regions) x 2 (Ranges) x 4 (Accounts) = 24 Total Ranges

At least 3 + 1 Reserved = 4

How many tiers?

• Assume 3 (Web, App, DB) + Spare = 4 4 (Tiers) x 4 (AZs) = 16 Subnets

CIDR RANGE: 10.20.0.0/16 (-> 10.20.255.255 - 65,456 IPs)

/16 per VPC - 3 AZ (+1), 3 Tiers (+1) - 16 subnets

/16 split into 16 subnets = /20 per subnet (4091 IPs)
