Creating Networks in AWS
- Create a vpc in nvirginia with six subnets in six az’s, Each subnet should be able to accommodate 250 devices
- Make a note of vpc id and subnet ids
- VPC CIDR: 10.10.0.0/16 (vpc-0218f7ed5bc6844f4)
- subnet 1: 10.10.0.0/24
- subnet 2: 10.10.1.0/24
- subnet 3: 10.10.2.0/24
- subnet 4: 10.10.3.0/24
- subnet 5: 10.10.4.0/24
- subnet 6: 10.10.5.0/24
- AWS allows the users to interact in 3 different ways
- Console (Website)
- CLI (Build commands and store them in a script)
- SDK (Write code in any language like python, java to automate)
Do the network creation from CLI
- Launch AWS Cloud Shell
- Search for aws cli to create vpc
- Refer Here for the create-vpc documentation
- Create vpc using command
aws ec2 create-vpc --cidr-block "10.10.0.0/16"
* Make a note of vpcId vpc-024ed3a4229091d54
* Now lets create a subnet1 cidr range = 10.10.0.0/24, az='us-east-1a'
aws ec2 create-subnet --vpc-id "vpc-024ed3a4229091d54" --cidr-block "10.10.0.0/24" --availability-zone "us-east-1a"
# subnet-06ac5ea3dd46770e9
aws ec2 create-subnet --vpc-id "vpc-024ed3a4229091d54" --cidr-block "10.10.1.0/24" --availability-zone "us-east-1b"
# subnet-002b56122d17bb032
aws ec2 create-subnet --vpc-id "vpc-024ed3a4229091d54" --cidr-block "10.10.2.0/24" --availability-zone "us-east-1c"
aws ec2 create-subnet --vpc-id "vpc-024ed3a4229091d54" --cidr-block "10.10.3.0/24" --availability-zone "us-east-1d"
aws ec2 create-subnet --vpc-id "vpc-024ed3a4229091d54" --cidr-block "10.10.4.0/24" --availability-zone "us-east-1e"
aws ec2 create-subnet --vpc-id "vpc-024ed3a4229091d54" --cidr-block "10.10.5.0/24" --availability-zone "us-east-1f"
