CloudFormation StackSets: automated cross-account/region deployments
Yesterday, AWS released CloudFormation StackSets. A StackSet is a set of CloudFormation stacks that can easily be deployed to multiple AWS accounts and/or multiple AWS regions. Before, each stack had to be deployed separately and custom scripts were required to orchestrate deploying to multiple accounts/regions. Therefore, this feature is bound to make the lives of AWS administrators a bit easier. There are loads of use cases for deploying stacks to multiple locations.
