Hi, I'm Shii-chan! Today I want to walk you through the AWS Weekly Roundup, a handy way to catch up on a week's worth of AWS news!

AWS Blog aws.amazon.com

What was announced?

The AWS Blog's Weekly Roundup for August 3, 2026, written by Micah Walter, is a weekly digest post. It pulls together this week's updates — everything from AI model pricing to monitoring, multicloud connectivity, and data management — into one readable article.

Why it matters

AWS ships a huge number of service updates every week, and tracking each one individually can be a lot of work. The Weekly Roundup condenses the week's most important announcements into a manageable read, which helps you avoid missing something important.

What changes

Here are this week's standout updates.

  • Amazon Bedrock: OpenAI's GPT-5.6 models got cheaper. GPT-5.6 Luna is down 80%, to $0.20 per million input tokens and $1.20 per million output tokens, while GPT-5.6 Terra is down 20%. Both took effect automatically on July 30, 2026, with no action needed from users
  • Amazon CloudWatch: A new fully managed collector for Prometheus metrics is here, supporting workloads on Amazon EKS, EC2, ECS, MSK, and OpenSearch Service, so you no longer need to deploy and manage your own agents
  • AWS Interconnect: Multicloud connectivity to Oracle Cloud Infrastructure (OCI) is now generally available, letting you connect AWS and OCI privately without going over the public internet
  • AWS IAM Identity Center: Extended multi-region support now replicates your Identity Center directory, so user access can continue even if the primary Region has an outage
  • Amazon S3 Tables: Now supports the Variant data type in Apache Iceberg V3 format, making it easier to handle semi-structured data like IoT sensor data or application logs without stuffing everything into JSON blobs

Dive Deep

The roundup also points to some practical resources: a guide for simplifying the AWS CLI installation, a guide for deploying the Kimi K3 model on Amazon SageMaker HyperPod or EKS, and a piece on streaming from Apache Kafka into Iceberg tables at up to 10 GB/s. On the events side, it also mentions AWS Summits planned for the second half of 2026 and community-run AWS Community Days.

Wrap-up

  • GPT-5.6 models on Amazon Bedrock got up to 80% cheaper, effective automatically from July 30, 2026
  • CloudWatch now offers a fully managed Prometheus collector
  • AWS Interconnect now supports multicloud connectivity to OCI
  • IAM Identity Center's multi-region support has been extended
  • S3 Tables now supports the Variant type in Iceberg V3, making semi-structured data easier to handle

This is a good read for engineers who use AWS broadly and want a quick catch-up on the week's major updates!
