Advanced Scheduling

The Kubernetes scheduler is responsible for placing pods on appropriate nodes in the cluster. While the default scheduler works well for most workloads, Kubernetes provides advanced scheduling features that give you fine-grained control over pod placement for specific requirements.

These advanced scheduling mechanisms help you:

• Target Specific Hardware: Ensure pods run on nodes with specific hardware or software requirements
• Optimize Co-location: Place related pods on the same node or zone for performance
• Implement Separation: Separate pods that shouldn’t run together for reliability or security
• Dedicate Resources: Reserve nodes for specific workloads or teams

You’ll learn about:

• Node Selectors: Simple label-based node selection
• Affinity and Anti-Affinity: Express complex scheduling preferences and requirements
• Taints and Tolerations: Control which pods can be scheduled on specific nodes
• AKS-Specific Features: Leverage Azure Kubernetes Service scheduling capabilities
• Combining Techniques: Use multiple scheduling methods together for sophisticated placement strategies
