"When an agent goes loose, you might find yourself: your S3 bucket has been deleted by mistake."Tsahi Duek puts security first when it comes to AI agents. Unlike regular workloads, AI agents execute actions on your behalf — sometimes running code. That means locking them into isolated sandbox environments, scoping their access to specific services, and never giving broad permissions to your entire AWS account.Watch the full interview: https://ku.bz/2r41YKBZbKubesploit

We just published Kubernetes Architecture in Financial Services, a free technical book about platform design and operations.Drawing on public engineering talks and case studies from seven banks, it examines:- Tenant boundaries beyond namespaces. - Shared delivery controls and application ownership. - Policy maintenance, exceptions, adoption, and reporting. - Cross-cluster identity, reliability, external dependencies, and cluster replacement.Each chapter starts with a real platform problem, compares different boundaries, and examines the operational cost of each option.Thank you to Buoyant, Sysdig, and Nirmata for supporting the book and its research.Download it for free: https://learnkube.com/kubernetes-architecture-financial-services

This case study shows how a team ran ServiceNow's MID Server on EKS as a StatefulSet and faked the EC2 metadata service so the agent would accept IRSA credentials.More: https://ku.bz/mdkryD536Kubesploit

Moving to Kubernetes doesn't replace your security practices, but it adds a layer on top.Rodrigo Bersa at AWS breaks down what carries over and what must change.What stays: least privilege, perimeter security, network access control, authentication and authorization.What changes:- Supply chain security — you're managing hundreds of images, not just VMs - Multi-tenancy by default — workloads share nodes; namespace isolation and network policies keep them separate - In-cluster auth needs its own model, separate from infrastructure-layer controlsWatch the full interview: https://ku.bz/dB7PDNt0vKubesploit

Guardrails are not one-size-fits-all. David Parry argues that AI systems touching Kubernetes need deterministic rules that match the company, the deployment model, and the compliance requirements around sensitive data.He points to code review and YAML inspection as places where these guardrails should be explicit and enforceable, not left to improvisation.Watch the full interview: https://ku.bz/c5J05syX3This interview is a reaction to Mai Nishitani's episode https://ku.bz/3hWvQjXxp.Kubesploit

A pizza order became a 15-container, 200-trace system.In Kube Signals episode two, Brian Teller and Mauricio (Salaboy) Salatino examine observability, state management, governance, and trust for non-deterministic agents.They discuss:- Why multi-agent runtimes can recreate monolith scaling - How OpenTelemetry exposes prompts, completions, and decisions - Why execution history turns agent trust into measurable evidenceWatch: https://ku.bz/TlVjXdnb6Kubernetes moves too fast to track everything.

On-prem apps talking to cloud services need a path — and there are three.Raglin Anthony explains: public internet with HTTPS (simple, but at the mercy of variability), AWS Site-to-Site VPN (private and encrypted), or AWS Direct Connect (a physical cable that bypasses the internet entirely — suitable for production and compliance workloads).Whichever path you pick, DNS resolution across environments is always the last thing you have to sort out.Watch the full interview: https://ku.bz/2XqMJnLVxKubesploit

AI does not just make the requested change. It often expands the scope.Pronomita Dey describes how AI-generated code can turn a simple automation into a much larger diff filled with comments, exceptions, and extra logic. That makes review harder, increases trust too early, and raises the need for guardrails, policy as code, and stronger pre-merge checks.Watch the full interview: https://ku.bz/lm5jTjdVN
