Unsticking Ourselves from Glue: Migrating PayIt’s Data Pipelines to Argo Workflows and Hera | DoKC Town Hall (00:23:17)
Unsticking Ourselves from Glue: Migrating PayIt’s Data Pipelines to Argo Workflows and HeraPresented by Matt Menzenski, Senior Software Engineering Manager, Payitgov
At PayIt, we’ve been deploying applications to Kubernetes almost since the beginning of the company. Our data workloads, however, have run instead in AWS Glue. This has worked well enough for the reporting use cases that have been the main focus of this team historically. However, at the beginning of 2022, the PayIt data team began building out a new data platform, and in the process, ran into a number of challenges with Glue. In this talk, I will share the difficulties that we encountered with building, deploying, and orchestrating ETL pipelines in AWS Glue, our decision process for moving those workloads into Kubernetes, and the ELT architecture that we’ve arrived at today.

Formula 1 telemetry processing using Apache Kafka on Kubernetes // Paolo Patierno (DoK Day North America 2022) (00:15:36)
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!

Kubernetes 360º - Data driven observability - from Secrets to logs // Ben Hirschberg (DoK Day North America 2022) (00:17:11)
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.
Shifting Left Stateful Applications In Kubernetes // Viktor Farcic (DoK Day North America 2022) (00:15:52)
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.
Medical - Healthcare Data on Kubernetes // Olyvia Rakshit & Prasad Dorbala (DoK Day North America 2022) (00:13:41)
From the DoK Day North America 2022 (https://youtu.be/YWTa-DiVljY)
ABSTRACT
Healthcare organizations are transforming their applications and embracing digital platforms for efficient patient care. Today, compute at the edge, plays a critical role in deploying innovative healthcare applications that promise new approaches to patient care. Connected care platforms at scale are turning to Kubernetes infrastructure for deployment of telehealth and telemedicine apps. These kinds of applications often need real time image processing and inferencing at the edge, which in turn, require a distributed application platform on Kubernetes. They also need secure foundations for a regulatory compliant framework for wider adoption.
To elaborate further, a distributed platform or a multi-cluster infrastructure is necessary for healthcare applications. All medical application platforms are data intense. For eg. Medical applications that need to stream video data, i.e move large quantities of data need secure connections from edge to cloud. Smart healthcare applications are also seeing the value of multi-cloud deployments.
The ability to choose different technologies like AI, data storage systems or some specific relational database systems is driving multi-cloud adoption in healthcare solutions. A multi-cluster connectivity fabric is thus needed for data intensive healthcare applications to distribute across geographical boundaries. The fabric needs to have inbuilt automation and the smarts to make the best use of compute resources in a distributed infrastructure, for improved patient healthcare.
Highly Available Postgres Clusters In Kubernetes // John Long & Jonathan Gonzalez (DoK Day North America 2022) (00:15:04)
From the DoK Day North America 2022 (https://youtu.be/YWTa-DiVljY)
ABSTRACT
A practical session about running Highly Available PostgreSQL in Kubernetes. The primary objective will be to demonstrate how to set up a reliable architecture in a Kubernetes cluster to achieve low RTO and RPO. This will be covered by going over the various Kubernetes native components of our fully open source operator CloudNativePG[0]. It will be demonstrated how these components allow for a simple adoption of PostgreSQL into Kubernetes environments. If time and technical constraints permit there will be a live demo at the end of the presentation; if for some reason that is not possible there will be a link to a recorded demo.

The Kubernetes Native Database // Jeffrey Carpenter (DoK Day North America 2022) (00:16:26)
From the DoK Day North America 2022 (https://youtu.be/YWTa-DiVljY)
ABSTRACT
In the software industry we’re fond of terms that define major trends, like “cloud native”, “Kubernetes native” and “serverless”. As more and more organizations move stateful workloads to Kubernetes, we’ve started to see these terms applied to data infrastructure, where they can get overtaken by marketing hype unless we work to define them.
In this talk, we’ll examine two different databases, TiDB and Apache Cassandra, in order to identify what it means for a database to be Kubernetes native and why it matters. We’ll look at points including:
- The differences between cloud native, Kubernetes native, and serverless
- How databases become Kubernetes native
- Benefits of Kubernetes native databases
- How Kubernetes can better support databases

From the DoK Day North America 2022 (https://youtu.be/YWTa-DiVljY)
ABSTRACT
Kubernetes has crossed the chasm, but what about stateful applications and databases? Join us for this panel discussion and learn more about how organizations are deploying different databases like PostgreSQL and Cassandra on Kubernetes, what are the benefits of running databases on Kubernetes, and how the ecosystem is working towards making these things boring, so you can focus on your applications! We will have an interactive discussion with the hosts and guests of the Kubernetes Bytes podcast, and open it up to the audience to ask questions and learn more about the what, why, and how about Databases on Kubernetes!

Architecting Your First Event Driven Serverless Streaming Applications on K8 // Timothy Spann (DoK Day North America 2022) (00:13:29)
From the DoK Day North America 2022 (https://youtu.be/YWTa-DiVljY)
ABSTRACT
Once you have built a topic in Apache Pulsar, you will quickly see the need to build event-driven applications. This can require a lot of decisions on what framework to use, where to run it, how to deploy it, and how to manage these applications on Kubernetes cloud natively.
I will walk you through step-by-step in building Pulsar Functions which is the easy way to design, test, develop, integrate, deploy, monitor, and manage serverless streaming applications in Java and Python.
Together we will build a full application as an Apache Pulsar function and enjoy the power of running it in the cloud for IoT events and add any routing, transformation, or machine learning that we need to accomplish our business requirements.
Through FunctionMesh we run on Kubernetes natively.
In this talk, you will deploy ML functions to transform real-time data on Kubernetes.
Fybrik - A Kubernetes based platform for governed data use // Flora Gilboa-Solomon, Alexey Roytman, Maryna Strelchuk & Barry Hijkoop (DoK Day North America 2022) (00:20:59)
From the DoK Day North America 2022 (https://youtu.be/YWTa-DiVljY)
ABSTRACT
Data is the foundation for business value. However, in many enterprises, it is spread across different data stores, public/private clouds, and on-premises. The use of data is governed by regulatory requirements and enterprise policies and enterprises face dynamic data residency challenges.
Fybrik (https://fybrik.io) is an open-source, Kubernetes-based infrastructure that enables easier access to data distributed across hybrid and multi-cloud environments, while enforcing data governance policy according to the business’s needs.
In this talk, we will share use cases from a pilot project carried out with ING (a multinational banking corporation). Fybrik enabled ING the use of their data across geographical borders, across clusters in a secure, automated, and compliant manner.

From the DoK Day North America 2022 (https://youtu.be/YWTa-DiVljY)
ABSTRACT
This talk will go through both the improvements that have been made in Kubernetes for batch analytic workloads as well as some of the current pain experienced by users and developers moving their workloads to Kube. In this talk you will learn about how we “cheated” back in the YARN and Mesos days to make things go fast, why Kubernetes doesn’t like those cheats, and what some alternatives are.
