Hi guys! So a few months ago I was helping out on a public-sector AWS Landing Zone, and one day the leadership team came to me with what sounded like a small request. They wanted one document that sum
TL;DR: I shipped a Bedrock Agent todo chatbot and then found I could read another user's todos via prompt injection. The fix that mattered most: promptSessionAttributes is a hint, not enforcement — re

AWS re:Invent 2024 has proven to be an exhilarating journey filled with deep learning, inspiring conversations, and plenty of walking! Here’s a recap of my first two days at this extraordinary event.
The day kicked off with an intensive workshop on layered VPC security. This level 300 session provided hands-on experience with:
Advanced routing configurations
Security layer implementation
Best practices for secure Amazon VPC deployment
My second session of the morning explored Control Tower customizations. It focused on scaling account provisioning while maintaining security compliance, using frameworks like AFT and CfCT. These tools help organizations scale account provisioning and enforce security compliance with ease.
The customization capabilities allow for dynamic adjustments, ensuring compliance without sacrificing agility.
The sessions highlighted combining hybrid architectures, including Local Zones and Outposts, to meet latency and connectivity requirements. Discussions also covered physical connectivity considerations for Outposts deployments and enterprise-scale solutions.
A key takeaway was understanding hybrid and edge networking solutions like Local Zones and AWS Outposts, which bring computational capabilities closer to users for guaranteed low-latency performance. While both options can serve the same purpose, it is important to note that AWS Outposts requires active connectivity to the control plane - which resides in AWS VPC.
The second day started with an insightful keynote by AWS CEO Matt Garman. He announced groundbreaking advancements in AI and cloud infrastructure. Highlights included the development of “Ultracluster,” a massive AI supercomputer built with AWS Trainium chips, and the launch of Trainium2 and Trainium3 chips, offering significant performance improvements. AWS also unveiled the “Nova” series of AI foundation models and introduced Aurora DSQL for faster database performance, reinforcing its leadership in innovation and scalability.
Before heading to the Expo, I made a stop at the Certified Lounge. It was a quiet space to relax, network with fellow AWS-certified professionals, and collect some stickers to personalize (yet again) my laptop. This small yet meaningful moment added a personal touch to my re:Invent experience.
This session focused on strategies for optimizing multi-tenant serverless architectures to enhance agility.
Key discussion points included:
Network Isolation Strategies: Ensuring tenant data remains isolated in multi-tier SaaS applications.
Routing Decisions: Techniques for efficient traffic routing between application tiers.
Tenant Deployment Models: Exploring options for deploying tenant-specific resources.
Connectivity Patterns: Leveraging tools like PrivateLink and AWS Lattice for secure and scalable service discovery and communication.
This session highlighted how multi-tenant architectures can balance agility and security while scaling to meet customer demands.
One standout session explored cell-based architecture, a design approach aimed at improving scalability and resilience by isolating workloads into independent cells.
Key principles included:
Fault Isolation Boundaries: Limit the blast radius of failures to individual cells.
Dimensional Monitoring: Drill down into site, AZ, or cell-specific metrics for better observability while reducing noise with aggregated alarms.
Staggered Deployments: Test changes in individual cells before scaling to the entire environment.
By adopting this methodology, organizations can build fault-tolerant systems and safely scale their infrastructure with minimal downtime.
The first two days at AWS re:Invent 2024 have been exciting and full of learning. Meeting new people, exploring ideas, and seeing the energy around innovation have made it a great experience. I’m excited to see what the rest of the event has in store!
