Throughout his career he constantly found himself using machine learning to solve infrastructure related problems that he didn’t want to toil with. The desire to automate away mundane tasks combined with a desire to solve the hard problems with maths is what led him to his current role as CTO of StormForge, which focuses on Kubernetes resource optimization.Kubernetes Autoscaling: Beyond One-Size-Fits-All<!--presentation title-->There’s no one-size-fits-all approach to Kubernetes autoscaling. Fitting the right pieces together requires a deep understanding of the various autoscaling dimensions and the open-source projects that can plug in to meet specific use cases.This session will explore the three key dimensions: cluster, horizontal, and vertical. We’ll start with the tools built into Kubernetes before moving onto the more advanced open-source projects—Karpenter and KEDA, which enhance flexibility and efficiency for each.Attendees will learn: Strategies for cluster, horizontal and vertical autoscaling, their challenges, and solutions that improve on or replace them How to assess workload requirements to choose the right mix of autoscaling tailored to specific app needs Best practices to optimize deployments for peak performance and cost-efficiency for dynamic workloads

It's got a simple interface built on top of Nix, meaning you can use over 100,000+ packages, We also make older package versions available, and it works across Linux and MacOS with x86_64/ARM/Apple Silicon chips. This is super important because Flox lets you build and version your environments. Then you can stack and share them with the people you want to collab with., while enjoying the power of your actual hardware, and the comfort of $HOME.Come join in for a live demo on this new, open-source tool, and learn how you can use and on the Flox project 🙂 Hosts: Nate Lee

This talk presents a new architecture for 2-node HA that gives you the resilience you need, and 33% cost savings.We'll cover:The challenge: real end user examples from hospitals, coffee shops and factory floors where 3-node HA proved problematic The problem space: existing alternatives such as external data stores and ‘witnesses’ — and why they fall short The blueprint: a new OSS-based 2-node HA design built on kairos, k3s, kine, and postgres Tradeoffs: when and where 2-node makes sense and how it stacks up against traditional 3-node k8s.

Cilium and Istio both provide compelling solutions for different layers in the network but also have some overlap. At KubeCon NA 23 we introduced the concept of the “CAKES stack” -- a modern application networking stack based on best of breed components for networking: Cilium, Ambient mesh (Istio), Kubernetes, Envoy, and SPIFFE/SPIRE. In this talk, we understand how these technologies complement each other to solve challenges around zero trust, observability, traffic policy enforcement, API management and global failover.

They long to be a real, running application, living in production, serving end users! But the epic journey to production is an arduous one, filled with cascading choices—choices concerning container build strategy, image registries, application configuration, adding and managing a database, migrating database schema, and Kubernetes-native development, to name a few. And who knows what other unseen forces lurk in the shadows! One wrong step could be catastrophic.It is up to us, the audience, to guide our hero; and to help them grow from source code to container image, to the first pitstop on their journey- running in a development environment. In this ‘Choose Your Own Adventure’-style talk, Whitney and Viktor will present a linear view of all of the choices that an anthropomorphized application must make as they try to find their way to the fabled land of development. Throughout the presentation, the audience will use a voting app to choose which path our hero application will take. Can we navigate CNCF projects and avoid pitfalls and dead-ends to get our application to development before the session time elapses?

A virtual cluster appears to be a full-blown Kubernetes cluster to the users, but it runs within a namespace of the host cluster. This allows users to have admin access to the cluster, use multiple namespaces in it, and manage global objects like CRDs.During the last year many new features have been added to vcluster, and we’ve seen it used for use cases that we hadn’t even imagined. In this talk we’ll provide some tips and tricks to help teams get more from their virtual clusters, and a few weird things you can do with them.Some things we’ll cover: How to share resources like ingresses from the host cluster, using vcluster’s isolated mode to automatically add network policies and Pod Security Standards to your virtual clusters, pausing and resuming virtual clusters, and monitoring and backing up virtual clusters. We’ll also cover some fun examples like using vcluster for shadow IT (users don’t need to have elevated privileges in the host cluster to start a virtual cluster) and running a virtual cluster inside of a virtual cluster.

He enjoys mentoring, training and leading teams to be successful with distributed systems concepts, microservices, devops, and cloud-native application design.The Future of Istio is sidecar-less<!--presentation title-->Every service mesh, including Istio, uses a sidecar proxy as its data plane. With this pattern, a mesh can intercept and enhance the capability of networking communication on behalf of an application. However, and unfortunately, this sidecar deployment pattern comes with a price to pay in terms of operations, complexity, and performance. With the advent of eBPF in modern operating systems, and some coordination with the Linux networking capabilities, we can look forward to improvements in service mesh architecture including moving away from a sidecar approach to a more transparent approach. In this talk we dig into the future of Istio, which I work on, to show how Istio can be run in a sidecarless mode.
