EC2 is one important service in AWS that you can launch a VM on your VPC. Based on hardware spec (CPU, memory, and network), there are several types of EC2 instances that are available on AWS. When you launch an EC2 instance, you need to specify VPC, subnet, security group, and ssh keypair. Therefore, all of these must be created beforehand.
Because of previous examples, the only last step is ssh keypair. Let's make an ssh keypair:
//create keypair (internal_rsa, internal_rsa.pub) $ ssh-keygen Generating public/private rsa key pair. Enter file in which to save the key (/Users/saito/.ssh/id_rsa): /tmp/internal_rsa Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /tmp/internal_rsa. ...
