Step 1: Choose Linux Image

• Ubuntu Server 20.04 LTS 64-bit (x86) - Web server
• Ubuntu Server 20.04 LTS 64-bit (Arm) - Database server

Step 2: Choose Instance type

• t3a.medium (2 vCPUs, 2.2 GHz, 4 GiB memory, EBS only) - Web server
• m6g.medium (1 vCPUs, 2.5 GHz, 4 GiB memory, EBS only) - Database server

Step 3.1: Create a VPC (first time only)

• Naming convention: region-environment-vpcname Example: apsouth1-prod-vpc01
• IPv4 CIDR block: 172.31.0.0/16
• Enable DNS hostname
• Tag: Name: same as the name above apsouth1-prod-vpc01

Step 3.2: Create a subnet (first time only)

• Naming convention: region-environment-subnetname Example: apsouth1-prod-subnet01
• IPv4 CIDR block: 172.31.0.0/16
• Tag: Name: same as the name above apsouth1-prod-subnet01

Step 4: Choose Storage

• 32 GiB General Purpose (GP2) - Web server
• 60 GiB General Purpose (GP3) - Database server

Step 5: Add tags

• Name: apsouth1-prod-web01

Step 6: Add security group (first time)

• Name: apsouth1-prod-webserver-security

• Name: apsouth1-prod-dbserver-security

Step 7: SSH Key pair

Create new (first time)

• name: apsouth1-prod-ssh01
• download .pem file and keep

Step 1: Associate an elastic ip with the instance

Attach a internet gateway to vpc

Create a new elastic ip

Associate the ip to the instance

(Optional) Might need to add mapping in route table of 0.0.0.0/0 to internet gateway
