Networking and Infrastructure Connectivity

Networking forms the foundation of distributed systems, enabling communication between services, applications, and infrastructure components. This collection examines networking concepts relevant to modern software development, from container networking and service meshes to load balancing and DNS resolution in cloud and Kubernetes environments.

The articles explore common networking challenges developers encounter when building distributed systems, including service discovery, network policies, ingress configuration, and connectivity issues that arise in containerized and cloud-native architectures. Topics cover both theoretical concepts and practical troubleshooting approaches.

Rather than diving into low-level protocol details, the content focuses on the networking knowledge developers need to design reliable systems, diagnose connectivity problems, and make informed architectural decisions. The emphasis remains on understanding how networking impacts application behavior and system reliability.

AKS Networking Clash: kubenet vs. CNI vs. CNI Overlay

Selecting the right network model is arguably one of the most critical architectural decisions you will make when deploying a Kubernetes cluster on Azure Kubernetes Service (AKS). This choice ripples through nearly every aspect of your cluster’s lifecycle, influencing how pods communicate, how efficiently you use your IP address space, which Azure services integrate seamlessly with your workloads, and ultimately, how well your infrastructure scales to meet future demands. It affects scalability, security posture, operational cost, performance characteristics, available integration options, and your long-term operational flexibility.
