To create a volume of 500 GB   aws ec2 --region us-east-1 create-volume --size 500 --availability-zone us-east-1d --volume-type gp2 size : in GB availability zone : This needs to be in the same availability zone as that of the instance that we are going to attach the EBS volume. To attach an EBS volume to the ec2 instance. aws  ec2 attach-volume --volume-id vol-9dfjhsdkfj93 --instance-id i-1234567899oasd  --device /dev/xvdb --region us-east-1 After attaching format the drive and mount it like what we do for a normal hard disk drive. To detach an EBS volume from the ec2 instance. aws ec2 detach-volume --volume-id vol-9dfjhsdkfj93 --region us-east-1

Here we are saving the pem file in our linux machine as the name mysshkey.pem  Modify the permission of the pem file. chmod 400 mysshkey.pem  To create a security group. aws ec2 create-security-group --region us-east-1 --group-name work_project --description "Project_for_work" --vpc-id vpc-12345  group name - It is the name that we are going to give for the security group description - The description that we are going to give for the security group To allow connection to a port aws ec2 --region us-east-1 authorize-security-group-ingress --group-id sg-12345 --protocol tcp --port 22 --cidr 10.100.0.0/16 aws ec2 --region us-east-1 authorize-security-group-ingress --group-id sg-12345 --pr...
