• Instance Type: t2.micro
• Key Pair: Jeremy-charlie-East2
• Network: jeremy-twoge-vpc, jeremy-twoge-public1
• Security Group: jeremy-twoge-sg (allow SSH, HTTP, PostgreSQL rules)

Create PostgresSQL RDS

• PostgreSQL / Free Tier / Single DB instance / jeremy-twoge-db / UN postgres PA 11111111 / connect to jeremy-twoge-ec2 / jeremy-twoge-sg /

Installation on EC2

# Update
