Running AI MCP Tools on Kubernetes with kagent

Bret and Nirmal explore AI agents in Kubernetes with Eitan Yarmush, Senior Architect at Solo.io. Eitan explains how AI agents work through three simple components (system prompts, LLMs, and tools), and demonstrates the kagent project, which provides a Kubernetes-native way to deploy and manage AI workflows. 🙌 My next course is coming soon! I've opened the waitlist for those wanting to go deep in GitHub Actions for DevOps and AI automation in 2025. I'm so thrilled to announce this course. The waitlist allows you to quickly sign up for some content updates, discounts, and more as I finish building the course.https://courses.bretfisher.com/waitlist 🍾 Also in this episode, we cover the Model Context Protocol (MCP), which standardizes how agents communicate with external tools, along with practical use cases like incident response, debugging workflows, and CI/CD integration. Eitan shows how to create an agent through a web interface.We also address the challenges including security concerns (MCP lacks built-in security standards), cost considerations, and technical limitations like context window constraints.

Could AI End Human QA?

Bret is joined by Andrew Tunall, the President and Chief Product Officer at Embrace, to discuss his prediction that we’ll all start shipping non-QA'd code (buggier code in production) and QA will need to be replaced with better observability. 🙌 My next course is coming soon! I've opened the waitlist for those wanting to go deep in GitHub Actions for DevOps and AI automation. I'm thrilled to announce this course. The waitlist allows you to quickly sign up for some content updates, discounts, and more as I finish building the course. https://learn.bretfisher.com/waitlist🍾 If AI causes us to ship more code, we’ll need more testing and QA. It’s unlikely that orgs will want to add staff just so they can use AI, so what’s the solution? Would we start relying more on production observability to detect code issues that affect user experience? Embrace is a mobile observability platform company that I first met at KubeCon London this year. Their pitch was that mobile apps were ready for the full observability stack and that we now have SDKs to let mobile dev teams integrate with the same tools that we platform engineers and DevOps people and operators have been building and enjoying for years now. I wanted to hear from observability experts on how they think this is all going to shake out. ★Show Links★Embrace websiteEmbrace GitHub repositoryEmbrace docs Check out the video podcast version here: https://youtu.be/HHpn3OqMrbU Creators & Guests Cristi Cotovan - Editor Bret Fisher - Host Beth Fisher - Producer Andrew Tunall - Guest You can also support my free material by subscribing to my YouTube channel and my weekly newsletter at bret.news!

AWS Graviton: The Great Arm Migration

Bret and Nirmal are joined by Michael Fischer of AWS to discuss why we should use Graviton, their arm64 compute with AWS-designed CPUs. 🙌 My next course is coming soon! I've opened the waitlist for those wanting to go deep in GitHub Actions for DevOps and AI automation. I'm thrilled to announce this course. The waitlist allows you to quickly sign up for some content updates, discounts, and more as I finish building the course. https://learn.bretfisher.com/waitlist🍾 Graviton is AWS' term for their custom ARM-based EC2 instances. We now have all major clouds offering an ARM-based option for their server instances, but AWS was first, way back in 2018. Fast forward 6 years and AWS is releasing their 4th generation Graviton instances, and they deliver all the CPU, networking, memory and storage performance that you'd expect from their x86 instances and beyond. I'm a big fan of ARM-based servers and the price points that AWS gives us. They have been my default EC2 instance type for years now, and I recommend it for all projects I'm working on with companies. We get into the history of Graviton, how easy it is to build and deploy containers and Kubernetes clusters that have Graviton and even two different platform types in the same cluster. We also cover how to build multi-platform images using Docker BuildKit. Watch the video version on YouTube. Includes demos. ★Topics★Graviton + GitLab + EKSPorting Advisor for GravitonGraviton Getting Started Creators & Guests Cristi Cotovan - Editor Beth Fisher - Producer Bret Fisher - Host Nirmal Mehta - Host Michael Fischer - Guest (00:00) - Intro (06:19) - AWS and ARM64: Evolution to Graviton 4 (07:55) - AWS EC2 Nitro: Why and How?
