Security Groups Best Practices   Leave a comment

Security Groups are like firewalls in Amazon AWS. Servers (known as instances) are added to a group. The group defines which inbound ports are permitted. If one uses the Virtual Private Cloud (VPC) option one can specify outbound ports as well.

There are countless ways to group instances into security groups. For example, one might put all the instances related to a project into one group. Or one could make an individual group for each instance. Identical instances (perhaps they are load balanced) could go in the same group. Or instances could be grouped by their common function such as placing all web servers in one group.

If you were creating a best practice for the use of security groups, how would you use them?
