  • #19 DoK community: Towards a K8s Native Streaming Application // Francesco Nobilia & Jeremy Frenay

    Starting from a simple application which can be deployed in every machine running Docker, we will go through all steps required to transform the simple app into a Kubernetes native streaming application. We will explain the theory and then exemplify the learnt concepts to define a recipe for running streaming applications on Kubernetes. We will focus both on cultural and technical tricks to help you successfully adopt streaming applications at scale.

    At the end of the talk, you will have a comprehensive view regarding all platform building blocks and application requirements needed to successfully run a streaming application on Kubernetes.

    Spoiler: you will hear several times the words Apache Kafka, Kafka Streams and Strimzi.



    Francesco Nobilia is an enthusiastic engineer focused on building the next generation of a self-service and cost-effective streaming data platform. Event-Drive addicted. Apache Kafka fun. Kafka Summit and Meetup speaker. Currently, he is Principal Engineer at Nutmeg.

    Jeremy Frenay is a platform engineer at Babylon Health.

    He has been leading the Babylon's Data Operations efforts since late 2017, building the Kafka based data infrastructure, the automation and the tooling required to support teams of software and data engineers working on data integration pipelines in a cloud-native environment.

  • #18 DoK community: DoK Panel - The State of State // Rosemary Wang, Lili Cosic, Tomasz Cholewa & Jacquie Grindrod

    Stateful vs stateless? We will stately be stating our statutes regarding the status of the state of statefulness and statelessness on k8s- oh yea!

    In the DoK Community, one of the main issues that folks have are how in the world can they flatten the learning curve when it comes to running stateful applications in k8s. That's why we've brought on 3 experts from 3 different countries to tell us what state state (intentionally doubled) is in!


    Rosemary Wang works to bridge the technical and cultural barriers between infrastructure engineers and application developers.
    She has a fascination for solving intractable problems with code, whether it be helping an infrastructure engineer learn to code or an application developer troubleshoot infrastructure failures. She also interfaces with vendors, clients, startups, and open source projects to find creative software solutions for infrastructure.
    When she is not drawing on whiteboards, Rosemary valiantly attempts to hack stacks of various infrastructure systems on her laptop while watering her houseplants.

    Lili Cosic is a Principal Software Engineer at Red Hat, working on OpenShift monitoring. She is also a kube-state-metrics, prometheus-operator and kube-prometheus project maintainer. Previously she worked at Weaveworks on the Weave cloud integration with Kubernetes and before that, she found her passion for Kubernetes operators at Kinvolk creating first operators. In her free time, Lili enjoys experimenting with Kubernetes, cooking and distributed systems.

    Tomasz Cholewa is the co-founder of Cloud Code Labs and he believes that good applications deserve even better environments where they can spread their wings and it's his job to help you create them. To achieve it he uses cloud and containers, but mostly he listens carefully to understand and use the right mix of proper technology and processes around it. His field of expertise is public cloud (AWS), containers and their orchestration engines - OpenShift and Kubernetes.

    Jacquie Grindrod is a developer advocate for HashiCorp with a focus on delivery and orchestration, where she’s able to apply her passion for solving problems with a holistic approach by bridging the gaps between teams and systems. In 2019, Jacquie was recognized as one of Canada’s Top 30 Under 30 Developers and has spoken at conferences including DevOpsDays Toronto and Grace Hopper Celebration.

  • #17 DoK community: Is k8s Even Ready For Data? Round II // Patrick McFadin & Jeffry Molanus

    In our inaugural DOKC meet-up, Patrick McFadin Developer Advocate at Datastax emphasized the challenges of running Cassandra on Kubernetes, concluding at one point that “Kubernetes might not be ready for Cassandra.” Since that meeting, the use of the open-source Container Attached Storage project OpenEBS as a simple and high performance per workload storage for Cassandra has proliferated.


    Also the Cassandra Operator from Datastax, aka “CaSS”, has progressed as well. So - where are we now? Is CaSS on CAS working well?

    • What is the future of collaboration between Datastax / Cassandra and MayaData / OpenEBS? 
    • Is Kubernetes now ready for Cassandra? 
    • What are the emerging technologies that might shape storage and Kubernetes in the near future?
    • What are the reasons people avoid running DBs on Kubernetes? What makes it easier?

    • #16 DoK community: HyperStore-C: S3 object storage managed by Kubernetes // Gary Ogasawara

      Cloudian’s HyperStore is S3-compatible object storage software focused on the enterprise market.  In this talk, I'll discuss how and why we are working on Kubernetes-managed versions of HyperStore, including where we are now and what we're looking.


      Gary Ogasawara is Cloudian’s first Chief Technology Officer, responsible for setting the company’s long-term technology vision and direction. Before assuming this role, he was Cloudian’s founding engineering leader. Prior to Cloudian, Gary led the Engineering team at eCentives, a search engine company. He also led the development of real-time commerce and advertising systems at Inktomi, an Internet infrastructure company. Gary holds a Ph.D. in Computer Science from the University of California at Berkeley, specializing in uncertainty reasoning and machine learning.

      • #15 DoK community: Reaching limits in K8s: A case study with Ingress Controller // Laurent Rouquette

        When talking about data, we usually think about big data and scale, and what do we do next. Such limits are sometimes a good problem to have. In this talk, we'll discuss our approach to this situation using the Ingress Controller.

        Laurent is a Software Development Engineer at Adobe. He started in Dev, went to Ops (sometimes referred to as "SRE" these days), then became a manager and now he's back to being an individual contributor. 

        This is all on purpose: he likes to do new things!

        He grew up in Marseille, France (go Olympique de Marseille!), but moved to the US right after college and actually he's never had a real job in Europe...

        When he isn't coding, he likes playing soccer (although he's been doing a lot of "watching" since March 2020).

      • #13 DoK community: Distributed Workloads on Kubernetes Operators to the Rescue // Sebastien Guilloux

        For our 13th installation of the data on k8s meetup, we will be talking with Senior Software Engineer Sebastien Guilloux from Elastic about Distributed workloads on k8s and how operators play a part in that!

        // Abstract:

        How easily can you run distributed workloads on Kubernetes? The initial deployment of your 10-nodes database might be easy to setup, but day-2 operations (changing the configuration, adding and removing nodes, version upgrades, etc.) are much more complicated.

        We'll discuss how operators can help you manage distributed workloads, and a few operator tricks we learned while working on ECK (Elastic Cloud on Kubernetes) - an operator for the Elastic stack.

        // Sebastien Guilloux Bio:

        Sebastien Guilloux is a senior software engineer at Elastic. He has spent most of his career working with distributed systems, building resilient applications, and orchestrating Apache Kafka and Elasticsearch nodes around the world. He currently works on writing a Kubernetes operator for the Elastic Stack, Elastic Cloud on Kubernetes (ECK).
