You can now launch T3 instance types when using Amazon RDS for Oracle . Amazon T3 instances are the next generation of the Amazon burstable general-purpose instance type that provide a baseline level of CPU performance with the ability to burst CPU usage at any time for as long as required. T3 instances offer a balance of compute, memory, and network resources and are ideal for database workloads with moderate CPU usage that experience temporary spikes in use.

T3 instances accumulate CPU credits when a workload is operating below baseline threshold. Each earned CPU credit provides the T3 instance the opportunity to burst with the performance of a full CPU core for one minute when needed. Amazon RDS T3 instances are configured for Unlimited mode, which means they can burst beyond the baseline over a 24-hour window for an additional charge. T3 instances are suitable for small and medium database workloads.

You can easily scale up to this new instance type by modifying your existing DB instance in the AWS Management Console . Please refer to the Amazon RDS User Guide for more details. Refer to Amazon RDS Pricing for pricing and regional availability.

You can now use an external Kerberos KDC to authenticate applications and users running on your EMR cluster with Amazon EMR release 5.20.0 or later. This feature allows you to connect multiple Kerberized EMR clusters to a centralized external KDC and allow applications running inside these clusters that use Kerberos for authentication to cross-authenticate with each other without your needing to establish a cross-realm trust. This capability will be especially useful in scenarios where you want multiple clusters to authenticate to a central data lake cluster to access data to submit and run jobs. You can also set up a cross-realm trust between an external KDC and an Active Directory domain on premises or in Amazon EC2. This allows users in your corporate directory to more securely access all Kerberized EMR clusters that authenticate to that KDC using their familiar Active Directory domain credentials.

For more information about configuring and using an external KDC on EMR, see Using Kerberos Authentication and External KDC Architecture Options in the Amazon EMR Management Guide.

This feature is now available in all supported regions for Amazon EMR .
