Asanka Abeysinghe, Chief Technology Evangelist at WSO2, introduces the cell-based reference architecture — a vendor-neutral, decentralised framework for cloud-native applications. The session explores microservices governance challenges, how Domain-Driven Design scopes service responsibilities into well-bounded cells, and how the cell-based model aligns architecture, development, and DevOps teams into cohesive autonomous units built around business domains.

Chris covers Azure updates including container app modernization, DDoS protection trends for H1 2021, and virtual network resizing in preview, alongside the general availability of GitHub Codespaces with a deep dive into how GitHub's engineering team uses Codespaces to develop GitHub.com. He also discusses Bicep and Infrastructure as Code on the Azure DevOps blog, plus upcoming sessions on AKS, application security, and cell-based cloud architectures.

When using Azure Kubernetes Service (AKS), there's a chance that kubenet might be the only possible choice due to your requirements. If so, you may still want to use Application Gateway Ingress Controller (AGIC) to leverage Azure Application Gateway's Web Application Firewall (WAF) capabilities. In this session, we will make the journey together to have a working AGIC in an AKS cluster with kubenet and managed identities.

A community Among Us stream with twelve cloud professionals discussing Kubernetes trade-offs in production, Windows 365 Cloud PC versus Azure Virtual Desktop, Azure Arc for multi-cloud app deployment, game engine choices between Unity and Unreal, and imposter syndrome in tech careers.

Open source projects and communities are the backbone of modern software development, yet the human side of building and sustaining them is rarely discussed as openly as the technology itself. In this episode, Chris is joined by JJ Asghar, Developer Advocate at IBM, who shares hard-won lessons from over a decade cultivating open source communities — from a small Linux distribution to OpenStack, Kubernetes, Tekton, and Istio. This is not a tools talk; it is a candid conversation about the soft skills, scoping decisions, and leadership approaches that separate thriving projects from those that burn out.

Inspired by the recent episode with Annie Talvasto, I wanted to put together a blog post that will introduce an ongoing series on Cloud With Chris. Before we introduce that series though, it's important that we first introduce the Cloud Native Compute Foundation (more commonly known as CNCF).

In the first tech-only episode of the new alternating format, Chris demonstrates GitHub Copilot's Technical Preview using Ruby and Python — from API integrations and regex generation to Azure Functions and IoT Hub messaging — and discusses the FAQ around code ownership, training data, and personal information filtering. The episode also covers CNCF fundamentals, Azure API Management policies with JWT token validation, Traefik proxy on Kubernetes, and the general availability of Azure Arc, including Azure SQL enabled by Arc.

In this episode, Chris is joined by Mert Yeter — software architect, Azure MVP, and Traefik Ambassador — for a live-demo-driven tour of DevOps on Azure. Starting with Azure DevOps Starter, Mert walks through spinning up a full CI/CD pipeline for a containerized .NET application in just a few clicks, covering Azure Container Registry, Azure Container Instances, and Azure Kubernetes Service. The session then dives into Traefik: an open-source cloud-native reverse proxy and load balancer with powerful pluggable middleware, dynamic service discovery, and a rich dashboard for managing Kubernetes ingresses. Whether you are new to containers or looking to level up your AKS deployments, this episode covers the essential building blocks.

The Cloud Native Computing Foundation (CNCF) gave us Kubernetes and Prometheus — but did you know there are over 90 more projects in the ecosystem? In this episode, Chris is joined by Annie Talvasto (CNCF/Kubernetes meetup organizer, Finland) to explore the most exciting CNCF projects across sandbox, incubating, and graduated tiers. They cover Helm for Kubernetes package management, Artifact Hub for centralised artifact discovery, Linkerd for lightweight service mesh with built-in observability and resilience, KUDO for declarative Kubernetes operator creation without deep Go expertise, and KEDA for event-driven autoscaling. Whether you're new to cloud native or a seasoned practitioner, this session will inspire you to explore — and contribute to — the wider CNCF landscape.

In part 1 of this Using Azure Arc for Apps series, we explored Azure Arc and Azure Arc enabled Kubernetes clusters. In this post, we'll be exploring Event Grid for Kubernetes. At time of writing, this approach is in public preview, so we may see certain limitations / features that are not yet available.
