Azure Container Instances run single containers without orchestration.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Does AKS manage worker nodes?<\/h3>\n\n\n\n<p>AKS manages control plane; node management can be partially managed by Azure but you control node images and pools.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can I run stateful databases on AKS?<\/h3>\n\n\n\n<p>Yes, with StatefulSets and CSI-backed Azure Disks but ensure backup and performance planning.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How do I secure workloads in AKS?<\/h3>\n\n\n\n<p>Use Pod Security Standards, network policies, Azure AD, Managed Identities, and image scanning.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is AKS free?<\/h3>\n\n\n\n<p>Control plane may be free; you pay for nodes, storage, load balancers, and other Azure resources.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How do I handle secrets in AKS?<\/h3>\n\n\n\n<p>Use Azure Key Vault with CSI Secrets Provider or Kubernetes secrets with strict access control.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can AKS autoscale down to zero nodes?<\/h3>\n\n\n\n<p>Cluster Autoscaler does not scale node pools to zero in all configurations; virtual nodes or serverless options enable scale-to-zero for workloads.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How often should I upgrade AKS?<\/h3>\n\n\n\n<p>Upgrade cadence depends on risk and support timelines; test upgrades in staging and run canary upgrades.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to choose node sizes for AKS?<\/h3>\n\n\n\n<p>Choose based on workload resource profiles and scaling needs; use specialized node pools for GPUs or high IO.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What telemetry should every AKS cluster have?<\/h3>\n\n\n\n<p>Cluster health, control plane metrics, node resource metrics, pod lifecycle events, and application-level SLIs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to prevent noisy neighbors?<\/h3>\n\n\n\n<p>Use resource requests\/limits, QoS classes, and node isolation via taints and node pools.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is AKS suitable for multi-region failover?<\/h3>\n\n\n\n<p>AKS can be part of multi-region architecture but requires external routing, data replication, and multi-cluster orchestration.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to perform disaster recovery for AKS?<\/h3>\n\n\n\n<p>Back up etcd-like state via manifests in Git, backup PVCs via snapshots, and test cluster recreation with IaC.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can I run Windows workloads on AKS?<\/h3>\n\n\n\n<p>Yes; AKS supports Windows node pools with Windows Server containers but requires extra planning.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to debug networking issues in AKS?<\/h3>\n\n\n\n<p>Check NetworkPolicy rules, Azure NSGs, pod IPs, and CNI logs; use tcpdump or network troubleshooting tools.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to manage costs on AKS?<\/h3>\n\n\n\n<p>Use autoscaling, spot instances, rightsizing, log sampling, and tag resources for accountability.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Should I use a service mesh in AKS?<\/h3>\n\n\n\n<p>Use a mesh when you need advanced traffic control, security, or observability; avoid if it adds unnecessary complexity.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to test upgrades safely?<\/h3>\n\n\n\n<p>Run upgrades in staging, use maintenance windows, use PDBs, and incrementally upgrade feeders first.<\/p>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p>AKS provides a managed Kubernetes control plane integrated with Azure services, enabling cloud-native deployments at scale while offloading some control plane operations. Successful AKS adoption balances automation, observability, security, and SRE discipline.<\/p>\n\n\n\n<p>Next 7 days plan (5 bullets)<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Day 1: Inventory current apps and map to AKS suitability.<\/li>\n<li>Day 2: Define SLIs\/SLOs for top three services and set up basic metrics.<\/li>\n<li>Day 3: Deploy a small AKS test cluster with monitoring and GitOps.<\/li>\n<li>Day 4: Run a controlled canary deployment and validate rollback.<\/li>\n<li>Day 5: Create runbooks for the top three incident types and schedule a game day.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">Appendix \u2014 AKS Keyword Cluster (SEO)<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Primary keywords<\/li>\n<li>AKS<\/li>\n<li>Azure Kubernetes Service<\/li>\n<li>AKS tutorial<\/li>\n<li>AKS architecture<\/li>\n<li>\n<p>AKS best practices<\/p>\n<\/li>\n<li>\n<p>Secondary keywords<\/p>\n<\/li>\n<li>AKS monitoring<\/li>\n<li>AKS security<\/li>\n<li>AKS autoscaling<\/li>\n<li>AKS load balancing<\/li>\n<li>\n<p>AKS node pools<\/p>\n<\/li>\n<li>\n<p>Long-tail questions<\/p>\n<\/li>\n<li>How to configure AKS with Azure AD authentication<\/li>\n<li>What is the best way to scale AKS workloads<\/li>\n<li>How to set SLOs for AKS services<\/li>\n<li>How to secure secrets in AKS with Key Vault<\/li>\n<li>How to run StatefulSets on AKS<\/li>\n<li>How to troubleshoot PVC mount errors in AKS<\/li>\n<li>How to implement GitOps with AKS and Argo CD<\/li>\n<li>How to optimize AKS cost with spot instances<\/li>\n<li>How to run GPU workloads on AKS<\/li>\n<li>How to migrate VMs to AKS containers<\/li>\n<li>How to set up CI CD for AKS<\/li>\n<li>How to perform AKS cluster upgrades safely<\/li>\n<li>How to configure Azure CNI for AKS<\/li>\n<li>How to use KEDA with AKS for event scaling<\/li>\n<li>How to enable virtual nodes in AKS<\/li>\n<li>How to backup AKS stateful applications<\/li>\n<li>How to implement network policies in AKS<\/li>\n<li>How to monitor AKS with Prometheus<\/li>\n<li>How to collect traces from AKS apps with OpenTelemetry<\/li>\n<li>\n<p>How to use service mesh on AKS<\/p>\n<\/li>\n<li>\n<p>Related terminology<\/p>\n<\/li>\n<li>Kubernetes cluster<\/li>\n<li>Control plane<\/li>\n<li>Node pool<\/li>\n<li>Virtual kubelet<\/li>\n<li>CSI driver<\/li>\n<li>Persistent Volume Claim<\/li>\n<li>Helm chart<\/li>\n<li>GitOps<\/li>\n<li>Argo CD<\/li>\n<li>Azure Monitor<\/li>\n<li>Prometheus<\/li>\n<li>Grafana<\/li>\n<li>OpenTelemetry<\/li>\n<li>Pod Security Standards<\/li>\n<li>NetworkPolicy<\/li>\n<li>Pod Disruption Budget<\/li>\n<li>Cluster Autoscaler<\/li>\n<li>Horizontal Pod Autoscaler<\/li>\n<li>KEDA<\/li>\n<li>Managed Identity<\/li>\n<li>Azure AD integration<\/li>\n<li>StatefulSet<\/li>\n<li>DaemonSet<\/li>\n<li>Taints and tolerations<\/li>\n<li>Resource requests and limits<\/li>\n<li>Spot instances<\/li>\n<li>Canary deployment<\/li>\n<li>Blue-green deployment<\/li>\n<li>Chaos engineering<\/li>\n<li>Velero backups<\/li>\n<li>OPA Gatekeeper<\/li>\n<li>Azure Policy<\/li>\n<li>Ingress controller<\/li>\n<li>Service mesh<\/li>\n<li>Load balancer<\/li>\n<li>GitHub Actions<\/li>\n<li>Azure DevOps<\/li>\n<li>Cost optimization strategies<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n","protected":false},"excerpt":{"rendered":"<p>&#8212;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[149],"tags":[],"class_list":["post-2090","post","type-post","status-publish","format-standard","hentry","category-terminology"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.5 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>What is AKS?
