You can now assign one or more AWS Identity and Access Management (IAM) roles to your Amazon Redshift cluster for data loading and exporting. Amazon Redshift assumes the assigned IAM roles when you load data into your cluster using the COPY command or export data from your cluster using the UNLOAD command. It uses the resulting credentials to access other AWS services, such as Amazon S3, securely during these operations. IAM roles enhance security of your cluster and simplify data loading and exporting by eliminating the need for you to embed AWS access credentials within SQL commands. They also enable your cluster to periodically re-assume an IAM role during long-running operations. Handling of data encryption keys for COPY and UNLOAD commands remains unchanged.

You can now view change sets before updating your stacks in AWS CloudFormation. This helps you understand the resource-level changes (e.g. adding, deleting, or modifying instances) which CloudFormation will apply to your live stack when you are updating your AWS infrastructure. Previously, you could not see the specific changes that CloudFormation would apply to your stack before submitting changes.  

You can now configure AWS WAF to block, allow, or monitor (count) requests based on Cross-Site Scripting (XSS) match conditions. XSS attacks are those where the attacker uses vulnerabilities in a benign website as a vehicle to inject malicious client-site scripts (like Javascript) into other legitimate user’s web browsers. This XSS match condition feature prevents these vulnerabilities in your web application by inspecting different elements of the incoming request.

In October of 2015, we added support for the popular open source MariaDB  database in Amazon RDS and have since seen rapid adoption by customers. Amazon RDS supports MariaDB instances running in Single-AZ or Multi-AZ configurations in all AWS regions. Today we are extending the RDS Service Level Agreement (“SLA”) that covers Multi-AZ instances for MySQL, Oracle, and PostgreSQL to include Amazon RDS for MariaDB. 

Starting today, Amazon RDS supports two new features for RDS for PostgreSQL database instances: the option to enforce only SSL connections to your instance, and near-realtime access to a set of 56 system and process metrics for your instance.

You can now scale up your existing ElastiCache for Redis clusters to a larger node type with a few clicks. Simply modify your node type by choosing from the available options and let ElastiCache manage the rest. Your existing node endpoints will persist, thus no application update is required. Scale up for Redis is designed to make a best effort to retain your existing data and requires Redis replication to succeed. For more details, please refer to Jeff Barr’s blog and ElastiCache Documentation .
