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 Disaster Recovery: Why Your Untested Backup Will Fail

Your cluster will fail. The question is not if, but when, and whether you can recover before customers notice. Most organizations discover their backup strategy does not work during an actual outage, when recovery time matters most and manual heroics cannot save you.

If you run Azure Kubernetes Service (AKS) in production, you need a recovery plan that engineers can execute half asleep at 2 AM. We will go through what to back up, how Velero works in day-to-day operations, when Azure Backup for AKS is enough, and how to design realistic failover with measurable Recovery Time Objective (RTO) and Recovery Point Objective (RPO).

The goal is simple: repeatable recovery procedures you have already tested, not a document that looks good in Confluence but fails during an incident.

Container Registry & Image Security in AKS Deployments

Securing Azure Container Registry for AKS needs more than a single control. This guide walks through a production-ready sequence: vulnerability scanning, image signing, RBAC, private endpoints, policy enforcement, and geo-replication. You get practical Terraform, Kubernetes, and pipeline patterns, plus clear trade-offs for real-world operations.

Your TLS Config is Probably Wrong: Five Audit Failures I Keep Finding

Production systems with HTTP endpoints wide open and TLS 1.0 enabled for backward compatibility that died in 2020 are still everywhere. If auditors haven’t flagged your encryption config yet, they will. This guide shows the fatal configurations that fail security audits and the Azure Front Door patterns that actually pass.

Multi-AKS Cluster Networking & Hub-Spoke Topology

Running more than one AKS cluster changes networking from a setup task into an operating model. This guide covers practical connectivity patterns, hub-spoke routing, cross-cluster DNS, ingress options, and decision criteria that help teams scale safely without adding complexity too early.

Observability in AKS CNI Overlay: When Pod IPs Hide Behind Nodes

CNI Overlay masks pod IPs behind node IPs through SNAT, breaking traditional observability. Network logs show nodes, application logs show pods. Without Container Insights, correlation IDs, and distributed tracing, you’re debugging blind. SNAT port exhaustion mimics network failures, and timestamp-based correlation is fragile. The cost of proper monitoring is trivial compared to debugging outbound connectivity at 3 AM without visibility.

Your Azure SQL Is Public Right Now. ISO 27017 Demands You Fix It

That SQL Server you deployed last week? Publicly accessible. That Storage Account? Same story. Azure defaults are security theater. ISO 27017 calls this a compliance violation, and your next audit will too. Stop trusting “cloud-native” to mean “secure” and start implementing VNets, Private Endpoints, and NSGs before your data becomes someone else’s problem.

AKS Cost Optimization: Resource Governance That Actually Works

AKS costs are brutally simple: node sizing, pod density, workload sprawl, and reserved capacity. If you don’t have visibility and governance, your cloud bill will punch you in the face—usually when it’s too late to react without pain. I’ve watched teams scramble to cut costs after the invoice lands, breaking production in the process. This guide is for practitioners who want to avoid that mess. No theory, no vendor fluff: just what actually works to keep AKS costs under control without sacrificing reliability.

Storage Architecture & Stateful Workloads in AKS

Stateful workloads in Kubernetes require understanding PersistentVolume architecture, Azure storage trade-offs, and backup strategies. This article covers PVC/PV patterns, Azure Disk vs Files performance profiles, Velero backup configurations, and multi-cluster replication patterns based on production experience.

Your appsettings.json Is a Compliance Violation

Hardcoded secrets aren’t just bad practice—they’re ISO 27017 violations with real consequences: failed audits, denied insurance claims, contractual penalties. That connection string in your appsettings.Production.json? It represents a compliance gap your organization probably doesn’t even know exists. Azure Key Vault with Managed Identity isn’t an optional security enhancement—it’s the minimum viable implementation of standards you already claim to follow.

AKS Cluster Upgrades: Zero-Downtime Operations That Actually Work

AKS cluster upgrades involve node replacement and pod eviction, which can cause service disruption without proper controls. This article explains cordon and drain mechanics, Pod Disruption Budget configuration, and multi-node-pool rollout strategies with validation-driven automation for reliable zero-downtime upgrades.

Why ISO Standards Actually Matter for .NET Developers

Cloud-native .NET development has transformed ISO/IEC 27001, 27017, and 27701 from abstract compliance requirements into concrete daily coding decisions. This guide shows .NET developers how security standards directly map to Azure Key Vault integration, Azure AD authentication, and proper logging—with real code examples demonstrating compliant vs. non-compliant implementations.

Pod Identity & Access Control in AKS: What Actually Breaks

Traditional AKS authentication relied on service principals and mounted secrets. Workload Identity Federation eliminates credential lifecycle problems, but introduces new failure modes. This article covers the operational realities: where credentials still leak, how RBAC layers compound across Kubernetes and Azure, and validation patterns that prevent identity failures in production.
