Kubernetes Autoscaling: Never Overpay for Cloud Again

Описание: Master Kubernetes autoscaling! Learn how HPA (Horizontal Pod Autoscaler), VPA (Vertical Pod Autoscaler), and Cluster Autoscaler work together to automatically scale your applications based on demand. Essential for Cloud Native Application Delivery domain.

⏱️ Video Chapters:
0:00 - Hook: Why Autoscaling Matters
0:45 - Types of Kubernetes Autoscaling
1:30 - HPA: Horizontal Pod Autoscaler
2:45 - HPA Metrics: CPU, Memory, Custom
3:45 - VPA: Vertical Pod Autoscaler
4:45 - Cluster Autoscaler
5:45 - Autoscaling Best Practices
6:45 - Real-World Scenarios
7:30 - Exam Tips & Summary

🎯 What You'll Learn:
✅ HPA - Scale pods horizontally based on metrics
✅ VPA - Adjust pod resource requests automatically
✅ Cluster Autoscaler - Add/remove nodes dynamically
✅ Metrics Server - Required for HPA to work
✅ Custom metrics with Prometheus Adapter
✅ When to use HPA vs VPA vs both

📊 KCNA Exam Tips from This Video:
• HPA scales number of pods (horizontal)
• VPA adjusts CPU/memory requests (vertical)
• Cluster Autoscaler adds/removes nodes
• HPA requires Metrics Server
• Default HPA target: 50% CPU utilization
• VPA and HPA should not target same metric
• Cluster Autoscaler works with cloud providers (EKS, GKE, AKS)
