Amazon DocumentDB (with MongoDB compatibility) is a fast, scalable, highly available, and fully managed document database service that supports MongoDB workloads. As a document database, Amazon DocumentDB makes it easy to store, query, and index JSON data.

PostgreSQL 13 Beta 1 is now available in the Amazon RDS Database Preview Environment, allowing customers to test the beta version of PostgreSQL 13 on Amazon RDS.  

Amazon SQS makes it easier to manage lists of queues by allowing callers to iterate through the results of ListQueues and ListDeadLetterSourceQueues APIs using a multi-page format. You can check the status of your request and receive the results in multiple pages by setting the MaxResults parameter to a value between 1 and 1000. You can receive up to a maximum of 1000 results in a single page. If there are more than 1000 results to display, you will receive a Next Token. Use the Next Token to receive the next set of results until the Next Token is null. This enables you to get all the results from your list request in multiple pages. We recommend you to use paginated lists instead of getting all the results in a single request. Furthermore, you can continue filtering your results of list requests using QueueNamePrefix.

You can now use Amazon Simple Queue Service (SQS) First-in, First-out (FIFO) queues in the EU (Milano) region. FIFO queues are designed to ensure that the order in which messages are sent and received is strictly preserved and that each message is processed exactly once. Amazon SQS is a fully managed message queuing service that makes it easy to decouple and scale microservices, distributed systems, and serverless applications. Building applications from individual components that each perform a discrete function improves scalability and reliability. Using SQS, you can send, store, and receive messages between software components at any volume, without losing messages or requiring other services to be always available.

Amazon Elastic Container Service (ECS) now publishes Elastic Load Balancer(ELB) lifecycle events for services attached to multiple load balancer target groups. ECS will emit service events when tasks are successfully registered or de-registered in target groups or in case of errors in the registration process. This enables you to track the progress of attaching your service to multiple target group and easily troubleshoot errors through events in the ECS service event stream as part of the update and describe service API responses as well as in the ECS Management Console. This functionality has already been available for services attached to a single target group but is now available for services attached to multiple target groups as well.

AWS Training and Certification has launched Migrating to the AWS Cloud , a self-paced digital course available on edX. This course helps you build skills by providing foundational knowledge on migrating to the AWS Cloud using AWS products and services.

To provide enhanced performance and scalability, Amazon RDS on VMware adds support for read replicas for MySQL and PostgreSQL databases. You can create read replicas of a source DB instance to serve high-volume application read traffic, thereby increasing aggregate read throughput. A read replica can also be promoted to become a standalone DB instance if the source DB instance fails.  

AWS Elemental MediaConvert now supports forensic watermarking using NexGuard . This feature enables you to watermark content for both mezzanine and OTT streaming contexts in order to enable content leak forensic workflows. You have access to an added layer of security and traceability for valuable pre-release and early release content, and a simple way for watermarking during video transcoding and OTT content preparation. NexGuard forensic watermarking in MediaConvert for pre-release content, including the recently announced NexGuard ClipMark for short form content as well as NexGuard Streaming for on-demand OTT content, enables full watermark automation when processing in AWS.

An Amazon Aurora Global Database now supports forwarding of write requests from a secondary region to the primary region, to simplify the development of your application code. 

You can now use the AWS Elemental MediaLive schedule feature to prepare a MediaLive channel input prior to switching to it. In the context of live video streaming, this functionality is also known as an ‘input cue’. Preparation of an input in advance of a switch helps reduce the latency of the scheduled switch action. For example, you may need to switch to an input for a postgame press conference that could start at any time. If the MediaLive schedule feature is used to prepare the input, you can switch to it with only a few seconds of latency.
