Securing Data-in-Transit with Wireguard for Kubernetes Cluster - Dhiraj Sehgal & Davide Sellitri,Tigera

Wednesday September 18, 2024 11:00 - 11:40 CEST

Room 0.14 (Level 0)

This talk delves into the transformative combination of WireGuard and Calico for enhancing network security in Kubernetes clusters. Despite the ubiquity of Kubernetes in microservice orchestration, securing the inter-node traffic often presents a significant challenge. We will first discuss the security risks associated with the non-encryption of inter-node traffic, such as data interception and potential injection of malicious payloads. It underscores the critical importance of implementing traffic encryption within Kubernetes clusters to thwart these threats. We examine WireGuard and ProjectCalico using its eBPF dataplane for securing traffic. The talk navigates the potential constraints, including the requirement for kernel support, the complexity of multi-cluster setups, and the compatibility issues across different environments.

What Was Life Like Before Open Source? - Dave Stokes, Percona

Wednesday September 18, 2024 11:00 - 11:40 CEST

Hall M2 (Level 1)

Those who forget history are doomed to repeat it at a much higher price tag. In these days of new restrictive licenses, It may help those who have grown up with open-source get a quick history lesson on what life was like back in the day when you bought everything - hardware, software, manuals, training - from a sole vendor. Interoperability was minimal, code sharing between different hardware brands was next to impossible, and a manufacturer's new line of products could instantly reduce your investment to zero value. Then came Unix (and later Linux), TCP/IP, and the revolution that produced our current outlook on software and systems. Help keep open-source from slipping away by understanding what we once endured and what many have to suffer through again.

A-Typical but Fruitful Public Sector Collaborations Through OSPO's - Nico Rikken, Alliander & Karel Rietveld, Dutch Tax and Customs Administration

Wednesday September 18, 2024 11:00 - 11:40 CEST

Room 0.49-0.50 (Level 0)

Collaboration in the public sector typically happens between similar organizations and through an overarching coordinating body. How a-typical is then the collaboration between the Dutch Tax Office and the semi-public Grid Operator Alliander. Yet the goals for their open source activities are similar and thus the OSPO's are collaborating to establish sound Open Source practices. Meanwhile there is a larger community of public and semi-public OSPO's that are taking on multiple shared goals. In this presentation Karel Rietveld and Nico Rikken will go over their learnings: - Unique benefits of an OSPO-collaboration that is national and consists of (semi-)public organizations - Practical examples of collaboration - How a small collaboration has grown to a larger collaboration - The road to the current working structure with working groups

Painless Multi-Tenant Kafka on Kubernetes with Istio at ASML - Thomas Reichel, ASML Holding & Dominique Chanet, Klarrio

Wednesday September 18, 2024 11:55 - 12:35 CEST

Hall C (Level 2)

ASML is building a self-service, multi-tenant data platform that enables teams to work independently on data products and applications. In a secure multi-tenant Kubernetes setup, tenants get an isolated view of the cluster, allowing them to deploy workloads independently of each other. Data sharing among tenants is governed by a global policy-based access control layer. Our challenge was to introduce a shared Kafka cluster into this setup, with proper tenant isolation and seamless integration with the global access control layer. We used Istio to enable zero-configuration authentication for Kafka clients operating inside the Kubernetes cluster. This allows Kafka authentication to be done with the Kubernetes-native tenant/namespace/serviceaccount idiom. A custom operator reconciles the tenant's topic definitions and topic access requests with the platform administrator's resource allocations and the global data sharing policy, and dynamically configures the right Kafka ACLs and resource quota.

Open Source at a Crossroads - Michael Meskes, NetApp

Wednesday September 18, 2024 11:55 - 12:35 CEST

Hall M2 (Level 1)

For the first time in history almost everyone uses open source, albeit often without getting the benefits of free software. Open source has accomplished unparalleled success in the IT industry, but with success comes challenges and risks. Over recent decades we have seen business models change while the industry and the users found the best ways to use open source. With software as a service we now see a fairly new but very successful approach, that goes hand in hand with open source, but is not without issues. This presentation will walk the audience through different approaches of monetizing and developing open source and examine the consequences of SaaS models for the open source ecosystem, both for business models and software development It will also point out how recent developments show the resilience of the Open Source world.

German Administration and Open Source - Thomas Fricke, Independent

Wednesday September 18, 2024 12:15 - 12:35 CEST

Room 0.49-0.50 (Level 0)

This talk describes a journey that began almost a quarter of a century ago. The first attempts to establish open source in Germany failed. Only with a cloud and digital sovereignty strategy was it possible to establish FOSS in the German administration. The speaker was involved in various initiatives, the Verwaltungsgitlab (OpenCode.de), the strategic papers of the IT Planning Council, OpenDesk, the founding of the Sovereign Tech Fund and is still centrally involved in the updating of the strategy. It provides an insight into the foundations of a private cloud strategy that ultimately paved the way for FOSS. The vision is a digitally sovereign administration cloud that ensures a secure and automated implementation of modern administration processes through DevSecOps as the engine of the processes.

Tackling Language Barriers in Open Source Docs: A Case Study of openEuler's Globalization Efforts - Helen Liu & Wang Jing, OpenAtom openEuler

Wednesday September 18, 2024 14:00 - 14:40 CEST

Room 0.11-0.12 (Level 0)

In today's interconnected world, open source thrives on collaboration, yet language barriers in documentation impede knowledge exchange. As languages like Chinese and Japanese gain prominence, native speakers play increasingly vital roles. Yet, the lack of universal understanding necessitates a two-step localization process, from the source language to English and then to local languages. Amidst this backdrop, in OpenAtom openEuler, a pioneering project born in China which has been spearheading internationalization efforts, we initiated G11N SIG, an instrumental globalization group in tackling these challenges head-on. As a maintainer of G11N and a social media operator who is deeply attuned to localization challenges, I bring firsthand experience and expertise to the table. In this session, we'll embark on a comprehensive exploration of openEuler's journey, delving into successful strategies, encountered challenges, and the lessons learned in surmounting language barriers. We'll shed light on AI's assistance in localization efforts and the empowering potential of social media in enhancing accessibility.

Lightning Talk: The Government and the Art of Infrastructure Maintenance - Powen Shiah & Mirko Swillus, Sovereign Tech Fund

Wednesday September 18, 2024 14:10 - 14:20 CEST

Room 0.49-0.50 (Level 0)

Join us in taking a look at how the Sovereign Tech Fund, a state-funded organization in Germany, has been developing ways to strengthen and support the free and open source ecosystem in the public interest. This ecosystem underpins the digital infrastructure, in particular the software components and tools, on which governments, private companies, and individuals rely. But what does it mean to strengthen this ecosystem? In this session, we’ll look at the different ways STF is putting public money to work for this mission. Some issues STF is working on include: a) Limited funding for long-term maintenance and security work b) Fragmented career and employment prospects for project maintainers c) Growing the pool of open source maintainers and contributors We’ll include lessons from the first two years of our existence, some insights from our survey of open source maintainers, as well ideas on how all the different parts in the FOSS landscape can work together for a more resilient and fair system. This is a work in progress, but we’re trying to ensure the software our societies depend on is sustainable in the long-term.

Lightning Talk: Millisecond Scale-to-Zero and the Quest to Never Pay for Idle Again - Felipe Huici, Unikraft GmbH

Wednesday September 18, 2024 14:20 - 14:30 CEST

Hall C (Level 2)

Cloud traffic is intermittent and bursty, but cloud bills are on 24/7. While many cloud providers have scale to zero mechanisms (i.e., putting an app to sleep if it's idle, and waking it up when requests for it arrive once again), these are slow, taking seconds or minutes to kick-in. In this lightning talk, we will show that leveraging tech from the Linux Foundation OSS Unikraft project (www.unikraft.org) we can fundamentally disrupt the semantics of scale to zero and autoscale in modern cloud deployments. Concretely, we will demo the ability to (1)*cold* start standard apps (web servers, databases, etc) in milliseconds; (2) scale them to 0 within milliseconds; and (3) wake them up within milliseconds of the next request coming in -- within an Internet RTT and thus not noticeable by end users. Finally, for a bit of fun, we will push the server to the limit, by loading it with thousands of these scaled to zero instances -- and take bets from the audience as to where the system might break.

Lightning Talk: With Great Traces Comes Great Costs: How to Reduce That Bill? - Prashansa Kulshrestha, Independent

Wednesday September 18, 2024 14:30 - 14:40 CEST

Hall C (Level 2)

Is Distributed Tracing an observability essential or just a high-maintenance diva? Hardly, anyone wants to compromise on a trace. For an adventure, try tracing everything and watch your cloud bill explode. Yes! All those spans that you decide to keep are expensive. If you use an external APM provider, god help you before you break your bank. While tracing has solved a number of problems, the cost problem is genuine and it keeps increasing with scale. In this presentation, Prashansa narrates her experiences when she was trying to balance the costs while keeping the traces sane. It’s a humorous journey lined with some failed experiments, small peaks of joy, troughs of sorrow and finally tumbling upon a good enough solution. Join her to know how you can also maintain good and sane enough tracing with a manageable bill, with some span tweaking magic, custom sampling algorithm and fully utilising OpenTelemetry capabilities. Trace smarter to save better.

Multi-Cloud Global Content Distribution at Cloud Native Speeds - Jiri Kremser, k8gb Project & Yury Tsarev, Upbound

Wednesday September 18, 2024 15:10 - 15:50 CEST

Hall C (Level 2)

If you’ve been globally distributing digital content for a while, you’ll understand that merely having numerous datacenters with advanced caching patterns isn’t sufficient. When your users need to retrieve an object that’s available in different locations worldwide, they should ideally be directed automatically to the location that’s nearest and fastest for the best experience. Cloud service providers typically offer services to handle this for you within their own clouds, but what if you are running a multi-cloud or hybrid environment? K8GB is a cloud-native solution that handles GeoDNS across heterogeneous environments and enables you to reach the same level of multiregion service resilience offered by cloud providers.

Scalable Multi-Node AI Workloads in Multi-Tenant AI Clouds Using SDN K8s Networking - Girish Moodalbail, NVIDIA Inc & Leonid Grossman US, NVIDIA

Wednesday September 18, 2024 16:05 - 16:45 CEST

Hall C (Level 2)

Within AI workloads, a few key traffic flows drive significant data movement between GPUs across nodes. Optimizing these flows for efficient bandwidth, low latency, and minimal jitter is critical to prevent GPU underutilization. Additionally, in the context of AI Cloud infrastructure, accommodating numerous users and concurrent AI workloads introduces competition for shared network resources, potentially impacting application performance. Hence, ensuring isolation between workloads within and across tenants is paramount. This session will explain ways to achieve network isolation (overlay virtual network topology) and efficient bandwidth (end-to-end QoS) between AI workloads using Open Source SDN solution, namely, Open vSwitch (OVS), Open Virtual Network (OVN), and OVN-Kubernetes CNI. With OVS-offloadable hardware the gains are much more significant.

Room 0.14 (Level 0)

One of the greatest out of the box features of K8s is its auto-scaling capabilities, which has a naive implementation or more advanced scheduling capabilities through native tooling. However, both of these models are reactive and not proactive in nature. What if we could employ proactive event-driven scaling of our clusters?! Over our many years of cloud native operations at scale, with the right tools we could! Enter KEDA (AKA Kubernetes Event-Driven Autoscaling). KEDA was built to make just this type of intelligent auto-scaling possible - this includes everything from event-driven and predictable actions like scaling up and down for predictable bursts of usage or shutting down dev clusters during specific and non-working hours, to managing scaling based on your workloads and message queues, or even your APMs and based on the metrics it ingests. In this talk we’ll walk through auto-scaling on steroids with KEDA, how it can be supercharged through CRDs, and in particular the cluster-API which now makes it possible to provision, update, customize and delete K8s clusters declaratively––that together are a game changer when it comes to the infinite scale K8s makes possible.

What Is an ABI, and Why Should You Care? - Shung-Hsi Yu, SUSE

Wednesday September 18, 2024 16:05 - 16:45 CEST

Hall B (Level 2)

Application Binary Interface (ABI), in contrast to the more often heard Application Programming Interface (API), is not as widely discussed, but is every bit as important as the latter. It is what allows us to run programs that are compiled 10 years ago on the latest system, and still expect it to work. In this talk, we will introduce the audience to the concept of ABI, explain its difference from API, and and lay out what exactly breaks ABI, as well as cover the symptoms of such breakage. Further more, we will detail how ABI breakage can be detected or prevented, and discuss some specific cases: Linux Kernel's ABI, Python's stable ABI, and Foreign Function Interface.

Linux Storage Stack Explained - Werner Fischer, Thomas-Krenn.AG

Wednesday September 18, 2024 16:05 - 16:45 CEST

Hall M2 (Level 1)

“Everything is a file” or, more precisely, “Everything is a file descriptor”: this statement alone shows the importance of the storage stack under Linux. To ensure that data can be accessed reliably and efficiently regardless of the selected file system and the actual physical storage location, numerous layers in the Linux kernel interlock seamlessly: Virtual File System (VFS), page cache, block layer with different I/O schedulers, so-called “stackable devices” such as device mappers and drivers are the most important components involved. Using the “Linux Storage Stack Diagram”, Werner explains this architecture clearly with the help of several concrete examples. He explains the different areas of the VFS (block-based, network, stackable, pseudo and special purpose file systems) and also goes into detail about the functionality and application areas of various file systems such as ext4 or btrfs. Werner then shows how the resulting BIOs (block I/Os) are processed by the block layer and I/O schedulers (and optionally via stacked devices) before they finally reach the device drivers and physical storage devices. Join this talk and understand how storage works in Linux :-)

RISC-V: Maturing an Open Standards Development Process - Philipp Tomsich, VRULL GmbH

Wednesday September 18, 2024 16:05 - 16:45 CEST

Room 2.31 (Level 2)

With its global uptake, the RISC-V specifications and RISC-V International, as the standards-development body, are facing an unprecedented challenges: the international adoption of RISC-V as an alternative, open-standards ISA and its role in various digital sovereignty initiatives worldwide are putting a geopolitical spotlight on the the standards and specifications released by RISC-V International. Safeguarding the protected status as a standards-development body and ensuring ongoing, constructive collaboration between geographies in the setting of future standards, requires a focus on policies and processes in our standards-development process. This session compares the existing RISC-V specification development with the ISO processes, and provides an outlook to some of the process improvements underway that will lead to an even closer alignment: the ultimate goal being a path to publication of the publicly available RISC-V specifications as international standards. We will provide an overview of the role of the RISC-V Technical Steering Committee, into the quality-gates a proposed standard must pass, and the consensus-building processes within each specification group.

Online Hands-on Tech Docs, the Easy Way! - Jorge Morales Pou, Broadcom

Wednesday September 18, 2024 16:05 - 16:45 CEST

Room 0.11-0.12 (Level 0)

Have you ever had the need to show a live version of what your technical documentation is presenting? Don't you agree that seeing things in action is the best way to convey your documentation goals? Have you ever had to deal with the complexity of the learners' heterogeneous environments? Or in other words, have the learners of your product wanted to learn how your project works but some have windows, some linux others mac, some constrained laptops, some don't have enough memory? For this problem online playgrounds for hands-on learning that help you deliver a hands-on experience via a web browser is the best way to go. But many of these do cost a lot of money, while this runs on containers on a simple Kubernetes cluster. In this workshop, we will demonstrate Educates, an open source hands-on workshop platform that can help you deliver hands-on learning experience as well as workshops and demos, in a very easy, reproducible and cost effective way. And we will be using an Educates workshop, which means Inception. This technology is the one used by VMware's Spring.Academy, Tanzu.Academy and Kube.Academy. I encourage you to spend this short time with us. It'll change your life.
