= First AWS VM =
We're going to set up a virtual machine in AWS now so you can start to get used to the process. You'll be repeating this several times during the course, try to learn a little more about it each time you do it. == Security group ops345first == A '''security group''' is a fundamental concept in AWS. It's not completely clear what it is. The closest thing you would have seen that's similar is a set of iptables rules. You can assign the security group (this set of rules) to one or more virtual machines. A security group with no rules does not allow any traffic to pass through. * Create a new security group "ops345first" with only the SSH port open. We'll look at security groups in more detail next week.
* Instance == VM. AMI == VM disk image.
* Lots of AMIs appear to be available, only Amazon Linux works with AWS Academy.
