You can now use Amazon Athena Workgroups – A new resource type that can be used to separate query execution and query history between Users, Teams, or Applications running under the same AWS account. Because Workgroups act as resources, you can use resource-based policies to control access to a Workgroup. For example, if you have two teams or different applications using Athena, you can limit access by assigning them to different Workgroups. You can also separate ad hoc usage from scheduled reports by assigning them to different Workgroups. Queries running in one Workgroup are not visible to users or applications running in a different Workgroup. You can also temporarily disable Workgroups, preventing users from running queries, or permanently delete them. Fine-Grained Access Control  for Tables and Databases defined in the Glue Data Catalog can further restrict access to specific databases and tables.  

You can now tag your Amazon Elastic File System (Amazon EFS) file system resources as they are created. Previously, you could add tags to your file system resources once they were created.

You can now use AWS CloudFormation templates to model and provision Amazon Kinesis Data Analytics for Java applications using version 2 of the Kinesis Data Analytics API. This improvement enables you to use AWS CloudFormation to deploy Kinesis Data Analytics applications in a safe and repeatable manner.

It’s a pity because four engines feel safer than two, but that nice warm feeling underlies the demise of  the Airbus 380 – which has happened largely as a function of running cost. At $26,000 to $29,000 an hour the four-engined 380 is not competitive with the $2000 per hour of the two-engined Boeing 737-800 …
