AWS CloudFormation has updated support for three services. You can now provision the following features using CloudFormation:
Amazon Simple Storage Service (S3) updated supportSpecify one or more transition rules for S3 buckets with versioning enabled. These define how S3 manages objects during their lifetime,such as automated transition of less-frequently accessed objects to low-cost storage alternatives and scheduled deletions. AWS Lambda updated supportEnable Lambda functions to access resources in a Virtual Private Cloud (VPC). Publish a version of a Lambda function. Versioning allows you to better manage your in-production Lambda function code by enabling you to publish one or more versions of your Lambda function. Create an alias that points to a Lambda function version that you specify. An alias is a pointer to a specific Lambda function version. Amazon Elastic MapReduce (Amazon EMR) updated supportDefine the properties of Amazon Elastic Block Store storage volumes attached to your Amazon EMR instances, such as their configuration or whether they are I/O optimized.
