How do you capacity plan for Azure AKS?

Capacity planning for Azure AKS (Azure Kubernetes Service) is crucial for optimizing resource utilization, ensuring application performance, and managing costs effectively. Proper planning helps in scaling applications seamlessly while accommodating potential workload changes.

Here are the key steps to consider when capacity planning for Azure AKS:

  • Understand Workload Requirements: Analyze the application workloads including CPU, memory, and storage needs based on usage patterns.
  • Utilize Azure Metrics: Leverage Azure Monitor and other metrics to track performance and scale accordingly based on real-time data.
  • Cluster Autoscaler: Implement the Kubernetes Cluster Autoscaler to automate scaling of node pools based on demand.
  • Set Resource Requests and Limits: Define resource requests and limits for your containers to ensure efficient allocation and prevent resource starvation.
  • Test and Iterate: Regularly test the performance and efficiency of your setup and adjust resource allocations based on analytics.

By following these steps, organizations can effectively manage the capacity of their Azure AKS environments.
