Season 5, Episode 6: Security Groups, Space Centers, and Serverless Updates

In Season 5, Episode 6, Karl and Jon are joined by Danielle Heberling, an AWS Hero, to dig into AWS Serverless updates from Q4 2025, including Amazon DynamoDB Global Tables now supporting cross-account replication, a new feature for displaying related resources for EC2 and VPC security groups, and IAM Identity Center now supporting multi-region replication. They also explore the feasibility of orbital data centers—before the conversation takes a fun turn as the guys debate whether data centers in space would technically be “in the cloud” or above it.

 

06:14 - AWS Serverless updates from Q4 2023 

This article summarized various serverless updates from AWS in Q4 2023, including Lambda durable functions, Lambda managed instances, provision mode for SQS, ECS express mode, and other improvements. The speakers discussed the benefits of these updates, particularly highlighting durable functions as a significant quality of life improvement for developers.

 

14:53 - Amazon DynamoDB Global Tables cross-account replication 

AWS announced support for replicating DynamoDB Global Tables across different AWS accounts. The speakers discussed potential use cases, such as disaster recovery and data lake setups, but also questioned the necessity of this feature given existing workarounds.

 

21:31 - EC2 and VPC security group related resources display 

A new feature was introduced allowing users to view related resources for EC2 and VPC security groups in the AWS console. The speakers agreed this would be beneficial for operators, making it easier to understand and manage security group configurations across various services.

 

25:03 - IAM Identity Center multi-region replication 

AWS announced support for multi-region replication of IAM Identity Center configurations. The speakers discussed the potential benefits for disaster recovery and compliance scenarios, as well as how it might simplify break-glass access procedures.

 

33:04 - Orbital data centers 

The podcast concluded with a discussion on the feasibility of orbital data centers, prompted by an article where AWS's CEO called them "pretty far from reality." The speakers debated the technical challenges, costs, and potential benefits of space-based data centers, ultimately agreeing that while interesting, such technology is likely far off in the future.
