AKS Health Check: Performance, stability, and security for mission-critical clusters

A deep-dive forensic analysis of your Azure Kubernetes Service. Eliminate crashes, cut cloud costs by up to 60%, and align with CNCF security best practices.

solution partner

Is your cluster showing these symptoms?

If your team is spending more time fighting fires than shipping features, your cluster is likely suffering from technical debt. We diagnose and cure:

Instability & deployment failures

Are you battling constant OOMKilled restarts or CrashLoopBackOff errors immediately after a deployment?

The "Black Hole" of costs

Are you paying for premium nodes that sit at 15% utilization? We often find that a lack of proper requests/limits is burning your budget unnecessarily.

Security blind spots

Are your containers running as root? Is your API server inadvertently exposed? Default AKS configurations are rarely secure enough for production standards.

The "It works locally" trap

Configurations that work on a developer's laptop often crumble under production load due to missing resource constraints.

Observability gaps

When downtime strikes, do you see the root cause instantly, or do you waste hours digging through raw logs?

Our methodology: The forensic examination

We don't just look at the dashboard; we perform a forensic examination of both the Control Plane and Data Plane.

01

Infrastructure & Architecture

  • Configuration Audit: We review AKS versioning strategies and Network Models (CNI vs. Kubenet) to ensure optimal throughput.
  • Node Pool Optimization: We identify "slack" resources and opportunities to implement Spot Instances for non-critical workloads to drive down costs.
  • Storage Efficiency: Detection of storage class misconfigurations (e.g., paying for Premium SSDs for simple log storage) that inflate bills without performance gains.

02

Security & Compliance (CNCF Standards)

  • Vulnerability Scanning: Full image scanning via Azure Container Registry (ACR) and integration with tools like Trivy.
  • Hardening: Verification of Network Policies, RBAC integration, and Pod Security Context analysis to prevent privilege escalation.

03

Observability & Reliability

  • Health Probes: Verification of Liveness and Readiness probes to ensure traffic is only sent to healthy pods.
  • Monitoring Stack: Assessment of your integration with Azure Monitor or Prometheus to ensure you have visibility when it matters most.

The toolchain

We utilize industry-standard, open-source scanning tools for an objective assessment, combined with manual expert review:

FAQ

No. The audit is completely non-invasive. We perform the check on a running environment using strict read-only access, ensuring zero downtime for your users.

Kubernetes is frequently over-provisioned. By identifying the gap between requested and used resources, and utilizing Spot Instances, we often see compute cost reductions of 40-60%.

Our focus is on the containerization and orchestration layer (Infrastructure), not business logic. However, we can include code review if requested as part of a broader App Modernization scope.

Yes. While we have an Advanced Specialization in Azure (AKS), our engineers are CNCF-certified and apply universal Kubernetes best practices applicable to any distribution or cloud.

While Azure Advisor provides high-level suggestions, our Health Check is a deep-dive forensic examination. We utilize specialized industry-standard tools like Polaris, Popeye, and Trivy to analyze granular configurations that Azure Advisor often misses—such as specific container security contexts, CNI vs. Kubenet network model impacts, and "slack" in resource requests that drives up costs.

Yes. The primary deliverable is a Technical Health Report containing specific YAML snippets to fix configuration errors immediately. However, if your team needs hands-on assistance applying these fixes, we can discuss an engagement to implement the Roadmap or assist with App Modernization.

We are designed to be fast and non-invasive. Since we use automated scanning tools combined with expert review, we can usually deliver your Technical Health Report and Cost Optimization Plan within a short timeframe, minimizing the delay between diagnosis and stability.

Yes. We specifically analyze storage performance to identify storage class misconfigurations. A common issue we find is workloads utilizing expensive Premium SSDs for simple log storage, which inflates costs without providing necessary value.

Absolutely. Our security analysis aligns your cluster with CNCF best practices. We review Image Vulnerabilities (ACR), Network Policies, and RBAC integration. These are fundamental controls required for major compliance frameworks, ensuring you aren't running containers as root or exposing your API server.

Our analysis targets the "Works on My Machine" syndrome, where pushed configurations fail under load. We review the actual running state of the cluster (Control and Data Plane)  to ensure that what is defined in your IaC matches the reality of the production environment, helping you reconcile drift.
