Bridging the DevOps to Data Divide with a Common Cloud Native Stack - Elad Hirsch, Terasky & Mey Beisaron, Forter

Tuesday November 12, 2024 9:10am - 9:35am MST

Salt Palace | Level 2 | 250 A

Despite DevOps being the norm and best practice for software development today, many organizations still treat their data differently from code, neglecting these well-established best practices over many years. This session will challenge this outdated approach and advocate for defining better “Data as Code” strategies, emphasizing the importance of applying the same rigor and methodologies used in software development to data operations. This session will teach how to run database services as part of Kubernetes infrastructure, just like current microservices, and apply the same SDLC methodologies to data operations as we do to code management with a common cloud native stack. In this session attendees will learn how to bridge the gap with a set of powerful CNCF Tools, including managing databases in K8s, how to embrace data as code, good GitOps practices and more.

Simplify Stream Data Processing with Declarative, Scalable K8s Native Technologies - Derek Wang & Vigith Maurice, Intuit

Tuesday November 12, 2024 9:45am - 10:10am MST

Salt Palace | Level 2 | 250 A

Stream processing and data analytics are crucial for various roles, including data engineers, platform engineers, DevOps, and many more. Simplifying real-time stream data processing while ensuring it's cost-efficient and resilient to K8s pod restarts or node upgrades remains a significant challenge. While existing stream processing solutions exist, they are often hard to manage, operationally demanding, and expensive. This presentation will share our journey in developing a generic open-source Kubernetes-native stream processing framework, it allows developers to effortlessly and quickly execute large-scale stream processing tasks without the burden of heavy and costly data processing platforms.

Kubernetes as Your DBA - Karen Jex, Crunchy Data

Tuesday November 12, 2024 11:55am - 12:20pm MST

Salt Palace | Level 2 | 250 A

Are you a systems admin or “infrastructure person” who suddenly had “looking after databases” added to your remit? This seems to happen a lot when everything’s running on Kubernetes and the databases are seen as just another part of the landscape. If so, what do you do? Quickly learn to be a database administrator? Hope the databases look after themselves? Or maybe implement a Kubernetes Operator, that has been created by database experts, to act as your virtual DBA? There are lots of moving parts to an enterprise scale database deployment, whether it’s on Kubernetes or not. You need high availability, disaster recovery, monitoring, upgrades… An Operator can do all of this for you, automating the initial deployment of a highly available database architecture, day to day management and monitoring of your databases, and even upgrades. We’ll look at what you want from an Operator, what you need to think about when choosing an Operator, and how easy it can be to get up and running.

Keyboards, Kiosks, and Kubernetes. Oh My! - Andrew Gracey, SUSE

Tuesday November 12, 2024 1:35pm - 2:00pm MST

Salt Palace | Level 2 | 250 A

Since containers are just fancy linux processes, we can shove anything in there, right?!? It turns out: Yeah, pretty much! The presenter has been exploring what you can do when you shove more interesting components (such as X11 and Pulse Audio) into containers. While it might feel like fitting a square peg in a round hole, it turns out this allows us to run kiosks and other HID workloads within Kubernetes! More importantly, it allows for maintaining host/workload decoupling and integrating into the CNCF ecosystem.

By containerizing your kiosk, you can:

Manage all of your devices with the same toolchain
Share extra resources on HID computers
Write GUI applications in any language or framework
Mitigate security issues (e.g. no shelling out from a print dialog)
Shrink update size All of this is open source using open source components at github.com/agracey/kiosk

Join the speaker for a deep dive into shenanigans required, lessons they learned, a demo, and how to get involved!

The Perfect Storm: Production Kubernetes Running on Ocean Vessels - Raghushankar Vatte, ZEDEDA

Tuesday November 12, 2024 2:10pm - 2:35pm MST

Salt Palace | Level 2 | 250 A

Edge computing is revolutionizing the shipping & logistics industry, enabling real-time insights & decision-making & providing a more seamless customer experience. This session shares the story of a Global F500 shipping company who turned to a Kubernetes-based packet core app to support their connected device strategy. Yet running K8s in the ocean, where you may have thousands of 3-node clusters vs a few 1,000-node clusters, requires a different approach. Distributed environments, with variables such as intermittent connectivity, security concerns & IT resources on the shore miles away, complicate these projects. Learn how they addressed these challenges with a scalable architecture across the entire fleet. This session will also provide an intro to EVE, developed within LF Edge from the Linux Foundation. EVE provides the ideal infrastructure for deploying K8s at the edge by addressing needs in areas like security, autonomy & scale for compute resources outside of secure data centers.

Tuesday November 12, 2024 2:40pm - 2:45pm MST

Salt Palace | Level 2 | 250 A

Kubernetes just turned 10 and it’s already driving a paradigm shift for modern multi-environment infrastructure. With the vast majority of organizations putting it at the epicenter of their long-term strategy, more than one third are deploying at the edge, with the adoption steadily growing year on year. As use cases across various industries increase, so do the stakes in the form of challenges; security, day 2 ops, cost, that require a new breed of solutions that are born for Kubernetes at the edge.

Tuesday November 12, 2024 2:50pm - 2:55pm MST

Salt Palace | Level 2 | 250 A

Governance, Risk, and Compliance (GRC) is an essential business mandate in our increasingly complex and interconnected world. While Risk Management Frameworks specify security requirements and posture required for an authorization to operate, this is just the first step. The creation of security artifacts, a tedious and time-consuming process, could take anywhere from 9-12 months. By creating a library of Risk Management Frameworks, organizations get ahead of the curve. In this session we review how treating compliance and policy as code can securely prepare enterprises for the future.

Tuesday November 12, 2024 3:55pm - 4:20pm MST

Salt Palace | Level 2 | 250 A

Have you ever considered having over 50% power savings for edge data centers with inter-container orchestration? Our session introduces a K8s-compatible Workload Allocation Optimizer (WAO) that utilizes a generic power consumption model for optimal deployment and scalability across cloud, edge, and MEC orchestration. WAO is designed to continuously process thousands of operational telemetry and adapt to changing conditions, and its optimization process significantly reduces energy consumption at the edge. The presentation will highlight a proof-of-concept case study featuring a real-world deployment of over 200+ servers. It will show how WAO's scalable cloud/edge orchestration capabilities and its efficacy as an energy-saving solution for various edge computing environments. Explore our GitHub repository to implement sustainable data center operations and know that the K8s-WAO can boost your energy efficiency while maintaining optimal performance in green edge computing.

From Sensors to Servers: Efficient Edge Computing with Akri and WebAssembly - Kate Goldenring, Fermyon & Yu Jin Kim, Microsoft

Tuesday November 12, 2024 4:30pm - 4:55pm MST

Salt Palace | Level 2 | 250 A

At the edge, thousands of sensors publish data. Servers on the edge must discover these devices and then continually process new data from them. Akri and SpinKube are open source projects that address these challenges, providing a seamless experience for connecting IoT devices to Kubernetes clusters at the edge. Akri discovers these devices and automatically deploys Pods to consume their data. SpinKube runs serverless WebAssembly (Wasm) applications as Pods on Kubernetes. Since Wasm has small binary sizes and sub-millisecond start up times, it's the ideal application type for resource constrained servers at the edge. This presentation will conclude with a demo of using Akri to discover MQTT-based devices and automatically deploy Wasm applications to the cluster. The deployed applications will be event-driven and triggered by new MQTT messages, ensuring precise resource usage. By the end of the talk, you'll have the tools to run efficient data processing applications at the edge.
