Amazon EventBridge now provides additional content filtering options for builders designing event-driven architectures. With event pattern content filtering, you can write complex rules that only trigger under conditions you specify. This helps reduce the amount of custom code needed in downstream services by handling content filtering at the event bus using a declarative approach. 

Amazon EC2 is transitioning On-Demand Instance limits from the current instance count-based limits to new vCPU-based limits to simplify the limit management experience for AWS customers. Usage toward the vCPU-based limit is measured in terms of number of vCPUs (virtual central processing units) for the Amazon EC2 Instance Types launched. 

AWS Managed Services (AMS) announces support for 8 additional AWS services. With this release, the total number of services supported by AMS has increased to 69, including AWS Transfer for SFTP, a much requested service. In addition to running AWS services within secure and operated AMS managed accounts, you can self provision and configure these services directly in the AWS Console or the APIs. These services fall into the second pricing tier for AMS that is lower for certain groups of AWS services where more of the day-to-day operations is handled by the service itself; 12% for AMS Plus and 18% for AMS Premium.

Amazon Personalize is a machine learning service which enables you to personalize your website, app, ads, emails, and more, with custom machine learning models which can be created in Amazon Personalize, with no prior machine learning experience. AWS is pleased to announce that Amazon Personalize now supports ten times more item attributes. Previously, you could use up to five item attributes while building an ML model in Amazon Personalize. This limit is now 50 attributes. You can now use more information about your items, for example, category, brand, price, duration, size, author, year of release etc., to increase the relevance of recommendations.

AWS RoboMaker, a service that makes it easy to develop, simulate, and deploy robotics applications, now supports creating simulation jobs in batch with a single API call. The new support for batch simulations allows developers to easily create multiple simulation jobs for use cases like automated regression testing and reinforcement learning model training. The batch API also provides a queueing capability so that a developer can now submit more simulation jobs than is possible with the existing concurrent job execution limit. The batch API will queue up all the submitted jobs and execute them in batches based on the concurrent execution limit.

You can now enable AWS X-Ray for your APIs in AWS AppSync, making it easier to trace and analyze user requests as they travel through the APIs to the backend data sources.

You can now use Amazon Elastic Filesystem (EFS) in AWS CodeBuild build jobs. This can be achieved by specifying the EFS file system Id in your CodeBuild Project . 

Amazon DocumentDB (with MongoDB compatibility) is a fast, scalable, highly available, and fully managed document database service that supports MongoDB workloads.  

Use the new Amazon CloudWatch metrics for Amazon DynamoDB Accelerator (DAX) to better understand your DAX clusters’ performance. Determine more easily whether you need to scale up your cluster because you’re reaching peak utilization, or if you can scale down because your cache is underutilized.
