Chapter 3. Let There Be Email!

You can, of course, use other email solutions, but Exchange is by far the most widely used email platform in corporations of any size.

Before you can go about installing the Exchange Server software, you first have to stand up a suitable instance in the VPC. Before you can even do that, you need to prepare the network a little. In this case you need to create a new, empty, security group and assign it to your VPC. You’re not going to do anything with this new group just yet, but you need to have it ready. Its purpose will be to hold the firewall rules that apply only to your Exchange server. Go ahead and create a new security group from the VPC tab and name it Exchange Server.
