New Features

FeatureDescription
Windows Operating System

Amazon EC2 now offers the Microsoft Windows Server 2003 R2 operating system on
all Amazon EC2 instance types.

For more information, refer to the Windows portal page or the Amazon EC2 Developer Guide.

Elastic IP Improvements

Amazon EC2 is upgraded with a series of networking improvements that result in
faster remapping of elastic IP addresses. Additionally, when an address is disassociated from an instance,
the connection will immediately be broken so you can reconnect to other instances.
These changes are transparent and do not affect the APIs or command line tools.

 

Known Issues

IssueDescription
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 Windows AMIs are large and can easily reach the 10 GB limit. Before rebundling, check the size of the C:\ volume.
Amazon DevPay and Windows instances

Amazon DevPay does not yet support Windows paid or supported AMIs. This means that you currently can’t create a Windows AMI and sell it through DevPay, or associate an Amazon DevPay product code with a Windows AMI.

Windows instance availability

Initially, Windows instances will only be available in a single availability zone. Until notified, do not specify an availability zone when using ec2-run-instances; Amazon EC2 automatically launches Windows instances in the correct zone.

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.
Limitation of AuthorizeSecurityGroupIngress 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.
