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 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.
