Using Amazon EC2 instances running Windows is similar to using instances running Linux and UNIX. The following are the major differences between instances that use Linux or UNIX and Windows: Remote Desktop—To access Windows instances, you use Remote Desktop instead of SSH. Administrative Password—To access Windows instances the first time, you must obtain the administrative password using the ec2-get-password command. Simplified Bundling—To bundle a Windows instance, you use a single command that shuts down the instance, saves it as an AMI, and restarts it. As part of this service, Amazon EC2 instances can now run Microsoft Windows Server 2003. Our base Windows image provides you with most of the common functionality associated with Windows. However, if you require more than two concurrent Windows users or need to leverage applications that require LDAP, Kerberos, RADIUS, or other credential services, you must use Windows with Authentication Services. For example, Microsoft Exchange Server and Microsoft SharePoint Server require Windows with Authentication Services. To get started using Windows instances, we recommend using the AWS Management Console. There are differences in pricing between Windows and Windows with Authentication Services instances. For information on pricing, go to the Amazon EC2 Product Page. Amazon EC2 currently provides the following Windows AMIs: Windows Authenticated (32-bit) Windows Authenticated (64-bit) Windows Anonymous (32-bit) Windows Anonymous (64-bit) The Windows public AMIs that Amazon provides are unmodified versions of Windows with the following two exceptions: we added drivers to improve the networking and disk I/O performance and we created the Amazon EC2 configuration service. The Amazon EC2 configuration service performs the following functions: Randomly sets the Administrator password on initial launch, encrypts the password with the user's SSH key, and reports it to the console. This operation happens upon initial AMI launch. If you change the password, AMIs that are created from this instance use the new password. Configures the computer name to the internal DNS name. To determine the internal DNS name, see Using Instance Addressing. Sends the last three system and application errors from the event log to the console. This helps developers to identify problems that caused an instance to crash or network connectivity to be lost. bundle() has three require paramters and one optional instanceId The instance you want to bundle s3Bucket Where you want the ami to live on S3 s3Prefix The prefix you want to assign to the AMI on S3 uploadExpiration The expiration of the upload policy. Amazon recommends 12 hours or longer. This is based in nubmer of minutes. Default is 1440 minutes (24 hours) bundle() returns a multi-demential array that contains instanceId, bundleId, state, startTime, updateTime, progress s3Bucket and s3Prefix. bundle('instanceId', 's3Bucket', 's3Prefix'); ]]> describeBundle() Describes current bundling tasks describeBundle() returns a multi-demential array that contains instanceId, bundleId, state, startTime, updateTime, progress s3Bucket and s3Prefix. describeBundle('bundleId'); ]]> cancelBundle() Cancels an Amazon EC2 bundling operation cancelBundle() returns a multi-demential array that contains instanceId, bundleId, state, startTime, updateTime, progress s3Bucket and s3Prefix. cancelBundle('bundleId'); ]]>
