Cost Optimization with Karpenter and StormForge
During this session, we will discuss the differences between Cluster AutoScaling (CAS) and recently-donated-to-CNCF Karpenter. With a sample application, we will explain how we performed a bake-off between CAS and Karpenter. Finally, we will show the importance of Requests and Limits and the extra cost gains by fine-tuning Requests and Limits with StormForge SaaS optimized live.
Demystifying Kubernetes Resource Management
We will embark on a journey to unravel the world of Kubernetes resource management, shedding light on foundational primitives and uncovering best practices and real-world scenarios over a 90-minute lab session. We'll demonstrate how requests play a pivotal role in Kubernetes scheduling. We'll delve into the pod Quality of Service (QoS) and its importance in a real-world scenario of node pressure. We will determine pod usage over key cAdvisor metrics, pinpointing a typical situation of a pod being throttled and impacting performance. We will deploy Resource Quotas and Limit Ranges while explaining the lessons learned in multi-tenancy on large Kubernetes deployments. By the end of this session, the audience leaves the room with a clear understanding of how to avoid performance degradation, avoid outages, provide better multi-tenancy, and ultimately reduce cloud costs.
