You can now tag your AWS Site-to-Site VPN connections, Virtual Private Gateways, and Customer Gateways upon creation. You can do this when creating these resources through the AWS Cloud Development Kit (CDK) or AWS Command Line Interface (CLI). By tagging resources at the time of creation, you can eliminate the need to run custom tagging scripts after resource creation. In addition, you can now set resource-level permissions when using Site-to-Site VPN APIs . This allows you to implement stronger security policies by giving you more granular control over who has access to these APIs. You can also enforce the use of tagging and control which tag keys and values are set on your resources.  

Amazon Elasticsearch Service now supports cosine similarity distance metric with k-Nearest Neighbor (k-NN) to power your similarity search engine. Cosine similarity is used to measure similarities between two vectors, irrespective of their sizes and is most commonly used in information retrieval, image recognition, text similarity, bioinformatics and recommendation systems.

Amazon Elasticsearch Service now supports the open source Learning to Rank plugin that lets you use machine learning technologies to improve the ranking of the top results returned from a baseline relevance query. With Learning to Rank (LTR) support, you can tune the search relevancy and re-rank your Elasticsearch query search results in information retrieval, personalization, sentiment analysis and recommendation systems.  

Amazon MQ now supports LDAP (Lightweight Directory Access Protocol), enabling you to authenticate and authorize Amazon MQ users using directory services like Microsoft Active Directory. LDAP support simplifies authentication and access control for Amazon MQ brokers. You can now authenticate your Amazon MQ users through the credentials stored in your LDAP server. You can also add, delete, and modify Amazon MQ users and assign permissions to topics and queues.  

Amazon FSx, a fully managed service that makes it easy to launch and run feature-rich and highly-performant file systems, is now available in the AWS Europe (Paris) Region. With Amazon FSx, customers can leverage the rich feature sets and fast performance of widely-used open source and commercially-licensed file systems, while avoiding time-consuming administrative tasks like hardware provisioning, software configuration, patching, and backups. 

AWS ParallelCluster is a fully supported and maintained open source cluster management tool that makes it easy for scientists, researchers, and IT administrators to deploy and manage High Performance Computing (HPC) clusters in the AWS cloud. HPC clusters are collections of tightly coupled compute, storage, and networking resources that enable customers to run large scale scientific and engineering workloads. 

AWS DataSync now enables you to automate and accelerate online data transfers between on-premises object storage and Amazon S3, Amazon Elastic File System (EFS), or Amazon FSx for Windows File Server over the internet or AWS Direct Connect. With DataSync you can now easily and securely migrate, archive, or replicate on-premises datasets containing petabytes of data and billions of objects from on-premises to AWS.  

AWS CloudHSM is now available in the Africa (Cape Town) and Europe (Milan) regions. 

Starting today, new general purpose Amazon EC2 M6gd, compute-optimized Amazon EC2 C6gd, and memory-optimized Amazon EC2 R6gd instances with local NVMe-based SSD block-level storage are now available. These instances are powered by AWS Graviton2 processors and deliver up to 40% better price performance and 50% more NVMe storage GB/vCPU over comparable x86-based instances for a wide variety of workloads, including application servers, micro-services, high-performance computing, CPU-based machine learning inference, electronic design automation, gaming, open-source databases, and in-memory caches. The local SSD storage provided on these instances is ideal for applications that need access to high-speed, low latency storage, as well as for temporary storage of data such as batch and log processing, and for high-speed caches and scratch files.

Distributor, a capability of AWS Systems Manager, now allows you to install and update software agents on instances running Oracle Linux 7.5, 7.6, 7.7, and 7.8. This support simplifies agent management for environments that include Oracle Linux instances.
