Karpenter: Best Practices and Cost Optimization Techniques

Karpenter is a Kubernetes node lifecycle manager launched in 2021 by AWS, it has joined the CNCF SIG Autoscaling and transitioned to the beta phase. Karpenter has become a de facto standard to maximize the scaling properties of Kubernetes, it has been adopted already by Azure into their managed Kubernetes service. As Kubernetes gains widespread adoption across organizations for mission-critical workloads, it becomes crucial to establish standardized approaches to scaling. This encompasses not only the technical aspects but also the rationale behind scaling decisions and the appropriate timing for it. Additionally, it is imperative to evaluate the costs, encompassing operational overheads, cognitive complexities, and environmental repercussions. In this session, we will examine best practices ant techniques that strike a harmonious balance between optimizing performance, controlling costs, and promoting sustainability within Kubernetes environments with Karpenter.
