Amazon EC2 Auto Scaling Warm Pools help applications scale out faster and save money by requiring fewer continuously running instances. With Warm Pools, customers can improve the elasticity of their applications by creating a pool of pre-initialized EC2 instances that are ready to quickly serve application traffic. Additionally, Warm Pools offer a way to save compute costs by placing pre-initialized instances in a stopped state.

AWS Control Tower is releasing four new, less restrictive, mandatory preventative S3 Log Archive guardrails and changing the guidance of the four previous, more restrictive, preventative S3 Log Archive guardrails from mandatory to elective. With these guardrail changes you can now separate S3 Log Archive governance for resources created by AWS Control Tower from governance for the S3 resources you create.  

Amazon GuardDuty is now available in the AWS Asia Pacific (Osaka) Region. You can now continuously monitor and detect security threats in the region to help protect your AWS accounts, workloads, and data stored in Amazon S3.

Amazon Textract is a machine learning service that makes it easy to extract text and data from virtually any document. We continuously improve the underlying machine learning models based on customer feedback to provide even better accuracy. Today, we are pleased to announce a quality enhancement to our table recognition feature. Starting today, Textract more accurately detects the outer boundaries, row and column boundaries, and content of tables. The accuracy is especially improved for the tables in receipts and invoices, but you will see improvements across many documents in finance, healthcare, legal, and public sector.

AWS CloudFormation StackSets announces the ability to deploy CloudFormation Stacks to multiple AWS regions in parallel. This reduces the overall stack set provisioning times and provides a performance improvement when using StackSets. StackSets extend the functionality of stacks by enabling you to create, update, or delete stacks across multiple AWS accounts and regions with a single operation. Currently, using StackSets you can specify the region order preference to deploy stacks across AWS regions in a sequential manner. StackSets now expands on that by providing the additional ability to specify deploying across AWS regions in parallel as part of the deployment preferences for the stack set.

AWS Backup now enables you to use cost allocation tags for
Amazon Elastic File System (Amazon EFS) backups within
AWS Billing and Cost Management. With cost allocation tags, you can get better transparency and visibility into your Amazon EFS backup costs. For example, you can allocate your Amazon EFS backup costs to different departments (e.g., finance, engineering) or analyze Amazon EFS backup costs across your various workloads to better understand and manage your costs.

AWS Amplify iOS can now be installed through the Swift Package Manager. iOS developers can interface with AWS services through Amplify iOS, which is a use case based client library. Developers have been importing Amplify iOS through dependency management tools like CocoaPods. With Swift 3.0, Apple introduced a native package management tool called Swift Package Manager that allows developers to manage these dependencies within their Swift project.

You can now launch RabbitMQ 3.8.11 brokers on Amazon MQ. This patch update to RabbitMQ contains several fixes and new features compared to the previously supported version, RabbitMQ 3.8.6.

With Amazon Interactive Video Service (Amazon IVS) you can now save your live video content to Amazon Simple Storage Service (Amazon S3). Saved video is available for actions like editing or replaying as a video on-demand (VOD).

Amazon ElastiCache now supports tag-based access control and adding tags to additional cluster resources. By using tags for access control, your AWS Identity and Access Management (IAM) users, groups, and roles get access only to the Amazon ElastiCache resources with matching tags. This provides you the capability to scale by reducing the number of distinct permissions you need to create and manage in your AWS account. You can define AWS IAM policies that grant or deny access to a resource based on its tags. Furthermore, you can use specific condition context keys to customize your AWS IAM policies to limit specific behaviors on Amazon ElastiCache resources. For a complete list of condition context keys for Amazon ElastiCache, visit the Amazon ElastiCache documentation .
