Explore cost-effective auto scaling strategies in this AWS Summit conference talk that demonstrates how to optimize cloud infrastructure costs using three powerful technologies. Learn to implement Karpenter for intelligent Kubernetes node provisioning that automatically scales compute resources based on workload demands. Discover how KEDA (Kubernetes Event Driven Autoscaling) enables event-driven scaling of applications and workloads beyond traditional CPU and memory metrics. Master CRaC (Coordinated Restore at Checkpoint) technology to dramatically reduce application startup times and improve scaling efficiency. Understand the integration patterns between these tools to create a comprehensive auto scaling solution that minimizes costs while maintaining performance. Gain practical insights into configuring these technologies together for maximum cost optimization, including best practices for workload scheduling, resource allocation, and scaling policies. Examine real-world scenarios where this combination delivers significant cost savings compared to traditional scaling approaches, and learn troubleshooting techniques for common implementation challenges.
