## Source File
- [[raw/Cloud & DevOps/Public-Cloud-Learning-Sessions/04_EKS/public-cloud-learning-sessions-eks-optimization-part-1-of-3-compute-optimization.md]]

## Summary
- 核心主题：EKS 计算优化，使用 Karpenter 实现自动扩缩容
- 问题域：Kubernetes 集群资源管理、成本优化
- 方法/机制：Karpenter 替代传统 Cluster Autoscaler，直接与 EC2 Fleet API 通信，基于成本和利用率进行工作负载放置和整合
- 结论/价值：简化数据平面管理，降低节点管理复杂度，实现更优的成本效率

## Key Claims
- Karpenter 与 Kubernetes workload scheduling constructs 原生集成
- Karpenter 直接与 EC2 Fleet API 通信，降低延迟
- Karpenter 提供工作负载放置和节点整合的原生体验
- Karpenter 原生支持 Spot 中断处理，使用 EventBridge 和 SQS

## Key Quotes
> "Carpenter not only does the auto-scaling bit, but it also removes the pain points of working with node groups."

> "Carpenter has native integration with Kubernetes and it complements the native Kubernetes spot pod scheduling constraints that is available for your workloads."

## Key Concepts
- [[Karpenter]]：开源 Kubernetes compute management tool，替代 Cluster Autoscaler
- [[Node-Pools]]：定义调度约束和容量限制
