Proper Kubernetes resource configuration ensures optimal performance, reliability, and cost-efficiency for your Prisme.ai deployment. This guide details best practices and recommended configurations.

The following guidelines help ensure optimal performance for a standard Prisme.ai deployment:

Best Practices for Resource Management

Implement these best practices to optimize Kubernetes resource usage:

Resource Requests and Limits

  • Set accurate resource requests to inform Kubernetes scheduler for optimal pod placement.
  • Configure resource limits to prevent resource starvation.

Autoscaling

  • Use Horizontal Pod Autoscaler (HPA) based on CPU/Memory utilization.
  • Set minimum and maximum replica counts for critical components like API Gateway and Runtime.

Node Pool Optimization

  • Configure separate node pools for CPU-intensive (Runtime) and memory-intensive (Elasticsearch, MongoDB) workloads.
  • Regularly monitor resource usage and scale node pools accordingly.

Monitoring & Alerts

  • Integrate resource monitoring with Prometheus/Grafana.
  • Configure alerts to notify resource constraints or spikes in utilization.

​
Resource Quotas & Limit Ranges

Apply resource quotas and limit ranges to manage resource consumption within Kubernetes namespaces effectively.

​
Persistent Storage Recommendations

Ensure reliability and durability by properly configuring persistent volumes (PVs):

  • Use Persistent Volume Claims (PVCs) with dynamically provisioned storage classes.
  • Recommended storage classes: SSD-backed storage (e.g., AWS EBS GP3, Azure Premium SSD, Google Persistent Disk SSD).
  • Regular backups and snapshotting via cloud provider capabilities or dedicated backup solutions.

​
Monitoring Kubernetes Resources

Use Prometheus and Grafana to continuously monitor resources:

  • CPU and memory utilization dashboards.
  • Persistent storage performance metrics.
  • Alerting rules for resource exhaustion.

Example Prometheus alert:

groups:
- name: resource-alerts
  rules:
  - alert: HighCpuUsage
    expr: sum(rate(container_cpu_usage_seconds_total[5m])) by (pod) > 0.9
    for: 5m
    labels:
      severity: warning
    annotations:
      summary: High CPU usage detected
