AWS Community Days have been in full swing around the world. I am going to put the spotlight on AWS Community Day Argentina where Jeff Barr delivered the keynote, talks and shared his nuggets of wisdom with the community, including a fun story of how he once followed Bill Gates to a McDonald’s!

I encourage you to read about his experience.

Last week’s launches
Here are the launches that got my attention, starting off with the GA releases.

Amazon EC2 X8g Instances are now generally available – X8g instances are powered by AWS Graviton4 processors and deliver up to 60% better performance than AWS Graviton2-based Amazon EC2 X2gd instances. These instances offer larger sizes with up to 3x more vCPU (up to 48xlarge) and memory (up to 3TiB) than Graviton2-based X2gd instances.

Amazon Q generative SQL for Amazon Redshift is now generally available – Amazon Q generative SQL in Amazon Redshift Query Editor is an out-of-the-box web-based SQL editor for Amazon Redshift. It uses generative AI to analyze user intent, query patterns, and schema metadata to identify common SQL query patterns directly within Amazon Redshift, accelerating the query authoring process for users and reducing the time required to derive actionable data insights.

AWS SDK for Swift is now generally available – AWS SDK for Swift provides a modern, user-friendly, and native Swift interface for accessing Amazon Web Services from Apple platforms, AWS Lambda, and Linux-based Swift on Server applications. Now that it’s GA, customers can use AWS SDK for Swift for production workloads. Learn more in the AWS SDK for Swift Developer Guide.

AWS Amplify now supports long-running tasks with asynchronous server-side function calls – Developers can use AWS Amplify to invoke Lambda function asynchronously for operations like generative AI model inferences, batch processing jobs, or message queuing without blocking the GraphQL API response. This improves responsiveness and scalability, especially for scenarios where immediate responses are not required or where long-running tasks need to be offloaded.

Amazon Keyspaces (for Apache Cassandra) now supports add-column for multi-Region tables – With this launch, you can modify the schema of your existing multi-Region tables in Amazon Keyspaces (for Apache Cassandra) to add new columns. You only have to modify the schema in one of its replica Regions and Keyspaces will replicate the new schema to the other Regions where the table exists.

Amazon Corretto 23 is now generally available – Amazon Corretto is a no-cost, multi-platform, production-ready distribution of OpenJDK. Corretto 23 is an OpenJDK 23 Feature Release that includes an updated Vector API, expanded pattern matching and switch expression, and more. It will be supported through April, 2025.

Use OR1 instances for existing Amazon OpenSearch Service domains – With OpenSearch 2.15, you can leverage OR1 instances for your existing Amazon OpenSearch Service domains by simply updating your existing domain configuration, and choosing OR1 instances for data nodes. This will seamlessly move domains running OpenSearch 2.15 to OR1 instances using a blue/green deployment.

Amazon S3 Express One Zone now supports AWS KMS with customer managed keys – By default, S3 Express One Zone encrypts all objects with server-side encryption using S3 managed keys (SSE-S3). With S3 Express One Zone support for customer managed keys, you have more options to encrypt and manage the security of your data. S3 Bucket Keys are always enabled when you use SSE-KMS with S3 Express One Zone, at no additional cost.

Use AWS Chatbot to interact with Amazon Bedrock agents from Microsoft Teams and Slack – Before, customers had to develop custom chat applications in Microsoft Teams or Slack and integrate it with Amazon Bedrock agents. Now they can invoke their Amazon Bedrock agents from chat channels by connecting the agent alias with an AWS Chatbot channel configuration.

AWS CodeBuild support for managed GitLab runners – Customers can configure their AWS CodeBuild projects to receive GitLab CI/CD job events and run them on ephemeral hosts. This feature allows GitLab jobs to integrate natively with AWS, providing security and convenience through features such as IAM, AWS Secrets Manager, AWS CloudTrail, and Amazon VPC.

We launched existing services in additional Regions:

Amazon Aurora PostgreSQL Optimized Reads is now available in the AWS GovCloud (US) Regions.
Amazon DocumentDB is now available in Europe (Spain), and Africa (Cape Town) Regions.
Amazon MSK now extends support for Graviton3 based M7G instances in Europe (London) Region.
Amazon EC2 G6 instances now available in Spain region and, High Memory instances now available in Africa (Cape Town) Region.
