Release: AWS CloudFormation on 2011-09-29
This release of AWS CloudFormation introduces the capability to update stacks, application bootstrapping features, and Identity Access and Management (IAM) resources. This release also contains new tutorials on creating stacks and learning the essentials of templates.
|Ability to update some resource properties in a stack
||You can now update properties for the following resources in an existing stack: AWS::AutoScaling::AutoScalingGroup, AWS::AutoScaling::LaunchConfiguration, AWS::AutoScaling::ScalingPolicy, AWS::CloudWatch::Alarm, AWS::ElasticLoadBalancing::LoadBalancer, AWS::RDS::DBInstance, and AWS::Route53::RecordSet.
For details about things to consider when updating a stack and steps to follow for updating a stack,
see Updating a Stack.
||AWS CloudFormation now provides a set of helper functions that you can use to deploy packages, files, and start services on your EC2 instances by simply describing them using resource metadata in your template. You can use this feature in conjunction with the new update stack capability to update software throughout the lifetime of your stack. In addition to bootstrapping applications, you can also bootstrap other application deployment and configuration services such as Opscode Chef and Puppet. For more details, see the whitepapers we have put together to show how these features work together.
||You can now use IAM resources to create users, groups, and policies. You can add users to groups. You can also create resource policies for Amazon Simple Storage Service (Amazon S3) buckets, Amazon Simple Notification Service (Amazon SNS) topics, and Amazon Simple Queue Service (Amazon SQS) queues.
For more information,
AWS::SQS::QueuePolicy. For IAM resource snippets, see IAM Template Snippets.
