Title

Autoscaling Kubernetes Workloads with Karpenter

Abstract

Dive into the innovative world of Karpenter, an open-source Kubernetes cluster autoscaler designed to enhance the efficiency and cost-effectiveness of cloud-native applications. This session will explore how Karpenter dynamically adjusts compute capacity to meet the needs of your workloads in real-time. Learn how to simplify cluster management, reduce over-provisioning, and optimize resource utilization. Whether you're a developer, DevOps engineer, or a cloud architect, this talk will equip you with the knowledge to leverage Karpenter for better resource management in your Kubernetes environment

Title

Multitenancy in Kubernetes - Hardcore trial and error

How we used multitenancy to reduce cost and improve developer experience.

Abstract

• The experiments
• All the pain
• The outcome
• Key takeaways
• Into the future
• The talk will focus mostly on vCluster and ephemeral environments, but also discuss such gems as kardinal, kcp, pgcat, and more...

 Title

Kubernetes Application Lifecycle Management: Disconnected,

Abstract

However, in the air gap several challenges become apparent as the services we are used to relying on are no longer there.

The OCI registry with the images, the Git repository with the manifests, and the tools running in the cluster applying these changes.

All of these services are running in the background, and required to make the delivery happen

Without these services, what do we do?

Zarf tackles the application delivery process in the air gap by standardizing the application packaging, attestation, and deployment process.

This presentation highlights problems faced in the air gap everyday such as managing the application lifecycle of complex applications.

By the end you will have an understanding of Zarf and the core problems it solves.
