Share the Ride: Robust Multi-Tenancy in Kubernetes at Uber - Sashank Appireddy & Apoorva Jindal, Uber

Friday November 15, 2024 11:00am - 11:35am MST

Salt Palace | Level 2 | 251 AD

Multi-tenancy in Kubernetes involves the coexistence of multiple users or teams (tenants) on a single Kubernetes cluster while ensuring isolation, security, and performance. Our use cases at Uber span from scenarios with disruptive neighbors to those with large container sizes, specialized hardware, sticky placement preferences, and dynamic resource scaling demands, necessitating robust isolation measures. In this proposal, we present a comprehensive exploration of multi-tenancy in Kubernetes, covering strategies, the challenges we have faced and the effective solutions implemented to overcome them at Uber. Further, we will deep dive into the key aspects of building and managing multi-tenant Kubernetes clusters, by establishing strong tenant boundaries leveraging the ideas around node pools and tightly integrating with namespaces.

Still Don't Do What Charlie Don't Does - Making CRD Changes Safer - Nick Young, Isovalent

Friday November 15, 2024 11:55am - 12:30pm MST

Salt Palace | Level 2 | 251 AD

Many Kubernetes installations use controllers that include Custom Resource Definitions (CRDs) to extend their capabilities. However, because CRDs can only have one version installed in a cluster at any one time, version and change management can be very difficult. This talk will benefit both controller implementers and users. For implementers, I have tips on how to more safely make API changes to their CRDs, and for CRD users, some tips on what to look out for when installing CRD updates. All of this is based on using experience from projects like Contour, Gateway API, and Cilium among others. Learn things like: Different CRD version management strategies - what’s worked and what hasn’t How to make schema changes like pluralizing a field or changing field validation in a safe way How not to make the same mistakes I did Expect to come away from this talk having learned from my painful experiences handling CRD changes badly, but also having heard a bunch of Simpsons references.

The Missing Talk About API Versioning & Evolution in Your Developer Platform - Stefan Schimanski, Upbound & Sergiusz Urbaniak, Independent

Friday November 15, 2024 2:00pm - 2:35pm MST

Salt Palace | Level 2 | 251 AD

In the realm of developer platforms, individuals without extensive experience in the cloud-native ecosystem are now venturing into the creation of Kubernetes-based APIs. Tools like Crossplane are transforming every platform engineer into an API designer. Ten years in, the ecosystem still offers little guidance on Kubernetes versioning and API evolution in practice. A naive understanding is not helpful, and many have been burned by relying on intuition. This talk will provide deep, yet applicable knowledge, starting from the first principles of the invariants to maintain when changing APIs in Kubernetes. It will cover tools like schemas, conversion, validation, and admission, and present very concrete and directly applicable API Evolution Patterns. These patterns will help navigate the life cycle of CRD-based projects. This talk aims to educate on how to evolve APIs effectively and safely without inadvertently breaking users.

This Platform Goes to 11: Boost Developer Productivity with Lessons from Salesforce - Joe Kutner, Salesforce

Friday November 15, 2024 2:55pm - 3:30pm MST

Salt Palace | Level 2 | 251 AD

Internal platforms play an essential role in boosting the productivity of developers who use cloud native technologies. That’s why Salesforce, a global leader in the cloud for more than two decades, evolved its existing collection of managed services and capabilities into a cohesive platform that delights developers. In this talk, you’ll learn how Salesforce's platform removes friction, unifies interfaces, and meets developers where they are with industry standard tooling. As you design and build your own platforms, you’ll be able to use the same principles that guided Salesforce to accelerate day-1 onboarding of new apps, increase the speed of the developer inner-loop and testing cycles, and reduce the time it takes to deliver new code to production. Our lessons learned will help you avoid missteps. Finally, you’ll learn how to measure developer satisfaction, performance, activity, collaboration, and efficiency to ensure that your platform delivers the most value for your developers.

Platform Engineering for Software Developers and Architects - Daniel Bryant, Syntasso

Friday November 15, 2024 4:00pm - 4:35pm MST

Salt Palace | Level 2 | 251 AD

Building on my KubeCon EU 2022 talk, "From Kubernetes to PaaS to... err, what's next", I'll introduce the topic of platform engineering through the lens of a software developer and architect. My primary goal is for developers to understand "what good looks like" with a successful platform build and help them understand how a platform can influence the SDLC (for better or worse!) Key takeaways from the session: - Explore how platform architecture influences software architecture and vice versa - Learn why the principles of coupling and cohesion apply to platform components (and configuration) in the same way as they do with software components - Understand what to expect from an effective platform, including how applications are built, shipped, and run - Learn about key platform metrics grounded in developer experience frameworks such as DORA, SPACE, and DevEx

Zero Downtime Upgrades at Scale: How Okta Manages Hundreds of Clusters Daily - Jérémy Albuixech & Kahou Lei, Okta

Friday November 15, 2024 4:55pm - 5:30pm MST

Salt Palace | Level 2 | 251 AD

How do you upgrade your K8s clusters? Perhaps a rolling update of nodes, with services moving around? Can you guarantee a zero-downtime upgrade? Will this method scale and support the velocity of production environments? Likely not. But fear not - you are not alone! At Okta, we maintain hundreds of clusters, each hosting >130 services, with node counts ranging from 20-400 and we are updating them daily. How do we do it? Without an out-of-the-box solutions we had to build our own and we want to share what we learned with all of you! In this talk Kahou and Jeremy will go over the challenges and successes, highlighting how their deployment method provides the foundational blocks to build extra features while reducing the blast radius when something goes wrong - thanks to quick rollbacks and a canary rollouts. In this session attendees will learn how we leverage open source technologies to tackle three main problems: how to scale, how to secure and how to upgrade clusters with no downtime.
