Known Issues

IssueDescription
Windows Reserved Instances Reserved Instances are not currently available for Windows.
Windows AMI launch times Windows AMIs take longer to launch than Linux/UNIX instances due to larger AMI sizes and multiple reboots.
Windows AMI sizes Installing software on Windows AMIs can cause them to become large and easily reach the 10 GB limit. Before bundling, check the size of the C:\ volume.
Limitation on drive mapping There is currently no support for volume attachment to devices beyond /dev/sdp on instances running Linux/UNIX and xvdp on instances running Windows.
Security group limitation AuthorizeSecurityGroupIngress does not allow port ranges for group grants when using the command-line tools or the Query API. This is only supported through the SOAP API.
Instance limit New users are limited to a maximum of 20 concurrent instances, but many of our customers use hundreds or thousands of instances. If you need a higher limit, go to http://www.amazon.com/gp/html-forms-controller/ec2-request.
