Abbey Russell, PM at Cockroach Labs, shared the backstory on how and why Kafka was created.    Along the way, you'll learn about   - Who Franz Kafka was   - Kafka's earliest use at Linkedin in 2010 - Why organizations like Uber/Coursera/Mailchimp use it today - Future of Data Streaming   To find out more about how organizations are benefitting from running streaming workloads on Kubernetes, check out our 2022 research report- https://dok.community/data-on-kubernetes-2022-report/  https://dokcommunity.slack.com/ https://dok.community/  About Data on Kubernetes Community (DoKC)   DoKC is an independent tech community where practitioners go to run data workloads on Kubernetes. It is managed by Constantia.io. We produce a range of resources for end users looking to run DoK including:   - DoK Landscape  An interactive landscape of products and services for running data workloads on Kubernetes. (https://dok.community/landscape/)   - Videos and Blogs Hundreds of videos and blogs including how tos, tutorials, use cases, case studies, and more. (https://dok.community/landscape/) (https://dok.community/blog/)   - DoK Reports DoKC works with an independent research firm to annually produce the industry’s only DoK-focused report. (https://dok.community/dok-reports/)   - Livestreams and Local Meetups  Weekly livestreams on DoK-related topics including demos, tutorials, visionary talks, panels, and more. (https://www.meetup.com/data-on-kubern...)   - DoK Days @ KubeCon  We host hybrid events twice a year for people to get together and learn in-person or online.

https://dokcommunity.slack.com/ https://dok.community/ ABSTRACT OF THE TALK   Fabian, Chris and Abhi will discuss their passion for roleplaying games, and what they can teach us about the power of community, improvisation, and using our creativity.

https://go.dok.community/slack https://dok.community/ https://youtu.be/KjiK6eXYO34 ABSTRACT OF THE TALK   In this talk Sergio is going to present different ways to store data at the edge using different databases and Long Horn as a storage class. All this running on a Raspberry Pi and showing and small application using a database running at the edge.   BIO   Sergio Méndez is a systems engineer and professor of operating systems at USAC Guatemala university. His work at the university is related to teaching and researching cloud native technologies with his students. He has experience working on DevOps, and MLOps using open source technologies at work. About open source communities, he is involved in the CNCF Community, promoting students into the CNCF Ecosystem and hosting a Cloud Native meetup in Guatemala. He has been a speaker at several conferences such as KubeCon, WTFisCloudNative, and Kubernetes Community Days. He is also a Linkerd Ambassador and author of Edge Computing systems with Kubernetes with Packt publisher.   KEY TAKE-AWAYS FROM THE TALK   How to storage data at the edge using databases

https://go.dok.community/slack https://dok.community/ Link: https://youtu.be/n_thXwyJNSU ABSTRACT OF THE TALK   Deploying Stateless applications is easy but this is not the case for Stateful applications. StatefulSets are the K8s API object that helps to manage stateful application. Learn about what Stateful sets are, how to create, How it differs from Deployments.    BIO   Passionate about Cloud Native, Kubernetes, Developer relations   KEY TAKE-AWAYS FROM THE TALK   This talk is focused on basics of StatefulSet, how StatefulSet differs from Deployments, How to manage Stateful app using StatefulSet

From the DoK Day North America 2022 (https://youtu.be/YWTa-DiVljY)   Video - https://youtu.be/4cPVRWOK-_E ABSTRACT Apache Kafka is the de facto data streaming platform used for ingesting vast amounts of data and processing them in real-time. Low latency analytics are vital if users are to react to events as fast as possible and to effectively shape future decision making. Together with Kubernetes, it allows to develop cloud oriented analytics solutions which are highly scalable. During this session, we will explore an Apache Kafka based solution running on Kubernetes to help a Formula 1 team gain insights during a race. The “real” data will come from a well-known racing game and will be processed by our application in real-time, making us feel like real track-side F1 engineers!

From the DoK Day North America 2022 (https://youtu.be/YWTa-DiVljY)   Video - https://youtu.be/Y4tdy9lctEI ABSTRACT Learn how customers are increasingly deploying stateful applications on Kubernetes to benefit from portability, economies of scale, and built-in orchestration capabilities. This talk will include how customers choose between using Kuberentes, or a data Software as a Service (SaaS) and stateful capabilities of Kubernetes across two dimensions - the application orchestration and the storage layer. Also learn about MariaDB SKYSQL, a database software as a service that runs thousands of StatefulSet Pods across multiple zones and regions on Kubernetes.

From the DoK Day North America 2022 (https://youtu.be/YWTa-DiVljY) Video - https://youtu.be/A1ch4AhKoeQ ABSTRACT If there’s one thing that everyone can agree on - it’s that the sheer scale and complexity of Kubernetes operations is growing constantly. What’s more, cloud native environments are becoming more and more expensive to operate and manage, as well as increasingly difficult to secure. On the bright side, there is a growing ecosystem of exceptional open source tools to help overcome this complexity, and provide greater situational awareness to what’s happening in your many and multiple Kubernetes clusters. In this talk, we’ll take a deep dive on how to understand everything that is happening with stateful workloads in your Kubernetes clusters from health to security - including the management and monitoring of your clusters, troubleshooting and debugging, through full security scanning in multiple data perspectives- from configMaps, Secrets, hostPaths and many more security driven checks for proper role-based access control, vulnerabilities and misconfigurations. We will demonstrate how you can have a 360º-view of your Kubernetes clusters in a single open source dashboard leveraging tools like Lens and Kubescape, and ultimately enforce policies with Open Policy Agent.

From the DoK Day North America 2022 (https://youtu.be/YWTa-DiVljY) Video - https://youtu.be/LymPjH6HA3E ABSTRACT Stateless apps are easy to manage. More often than not, a Kubernetes Deployment, with a Service, Ingress, and Horizontal Pod Autoscaler (HPA) is enough. Almost everyone can do it. But, when it comes to stateful applications, things become a bit more complicated. We might need a database and storage. We might need to manage database users and schema. We might need to consider quite a few other things. Stateful apps are harder for everyone, especially if we want to shift left and enable developers to do it themselves. In this talk, we'll try to make the management of stateful applications easy for everyone. We'll accomplish that by creating easy-to-consume services that are made specifically for the needs of our organizations. We'll see how to create new Kubernetes Custom Resource Definitions (CRDs) and controllers using Crossplane. Those controllers will envelop all the tools, resources, and processes we might need. As a result, ops can focus on creating such services while everyone else can consume them (create and manage everything related to stateful apps) without opening JIRA tickets and waiting for others to complete their tasks.
