Cloud Computing and Cloud Architecture

Cloud computing has fundamentally transformed how modern applications are designed, deployed, and operated. This collection examines the practical aspects of building and running systems in cloud environments, including major platforms like Microsoft Azure, Amazon Web Services, and hybrid cloud scenarios that combine on-premises and cloud infrastructure.

The articles cover cloud-native architecture patterns, infrastructure as code, containerization, serverless computing, and the operational challenges teams face when migrating to or optimizing cloud workloads. Topics include cost management, security considerations, resilience patterns, and the trade-offs inherent in different cloud service models from IaaS to PaaS and SaaS.

Rather than focusing on vendor-specific features in isolation, the content explores how cloud technologies integrate into real-world development workflows, DevOps practices, and the broader software delivery pipeline. The emphasis remains on practical decision-making that considers both technical capabilities and organizational constraints.

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.
