Azure Kubernetes Service (AKS), following best practices can help ensure your clusters are secure, efficient, and reliable. Here are some key areas to focus on:
Cluster and Pod Security
- Secure API Server Access: Use Microsoft Entra ID and Kubernetes RBAC to control access to the API server.
- Pod Security Policies: Implement policies to restrict pod capabilities and enforce security standards.
- Container Image Security: Use trusted registries and scan images for vulnerabilities.
Networking and Connectivity
- Network Policies: Define network policies to control traffic between pods.
- Ingress Controllers: Use ingress controllers and web application firewalls (WAF) to manage and secure external access.
Resource Management
- Resource Quotas: Set resource quotas to manage resource allocation and prevent overuse.
- Pod Disruption Budgets: Use these to maintain application availability during maintenance.
Monitoring and Logging
-Centralized Logging: Implement centralized logging for better visibility and troubleshooting.
-Monitoring Tools: Use tools like Azure Monitor and Prometheus to track cluster performance and health.
Business Continuity and Disaster Recovery
- Regular Backups: Schedule regular backups of your data and configurations.
- Disaster Recovery Plans: Develop and test disaster recovery plans to ensure quick recovery from failures.
Cost Optimization
- Right-Sizing Resources: Choose appropriate VM sizes and scale resources based on demand.
- Auto-Scaling: Implement auto-scaling to adjust resources dynamically.
