Azure Kubernetes Chronicles part 4

Azure Kubernetes Chronicles part 4: Dataprotection Welcome back to the Azure Kubernetes Chronicles! In previous episodes, we explored network-related topics like container network interfaces, eBPF, and observability in Azure Kubernetes Service (AKS). But securing an AKS cluster goes beyond networking and runtime security — it extends to protecting, recovering, and managing data. In this episode, we’re shifting gears to focus on a topic that’s equally critical but often underestimated: data protection in AKS. While Kubernetes brings agility and scalability, it also introduces complexities in securing persistent storage, managing sensitive secrets, and ensuring compliance with evolving regulations like NIS2 and DORA. ...

Azure Kubernetes Chronicles

Azure Kubernetes Chronicles Networking using eBPF Welcome back to the Azure Kubernetes Chronicles, a blog series dedicated to unraveling the complexities of Kubernetes on Azure. In the first edition, we explored the fundamentals of the Container Network Interface (CNI), its role in Kubernetes networking, and how it powers communication within clusters. Building on that foundation, this next episode delves into the transformative impact of eBPF (extended Berkeley Packet Filter) when integrated with CNI. By combining these technologies, we unlock new possibilities for enhancing networking, security, and observability in Kubernetes environments, particularly on Azure Kubernetes Service (AKS). ...

Zero Trust in the Cloud

Zero Trust in the Cloud A Simple Path to Securing Cloud Infrastructure Created by Microsoft Designer Introduction In the world of cybersecurity, traditional network perimeter security models are no longer sufficient to protect against increasingly sophisticated threats. As cloud adoption continues to grow, ensuring robust security measures for both data and resources is critical. Enter Zero Trust — a security framework that shifts the paradigm from implicit trust to “never trust, always verify.” In this blog post, we will explore what Zero Trust is, the pros and cons of this security approach, and how to implement Zero Trust in both Microsoft Azure (Azure) and Amazon Web Services (AWS) environments. ...
