Navigating Disaster Recovery in Kubernetes and CNCF Crossplane 
Navigating Disaster Recovery in Kubernetes and CNCF Crossplane Carlos Santana This document discusses disaster recovery strategies in Kubernetes and Crossplane. It defines disaster recovery as business continuity planning for larger, less frequent events like natural disasters or technical failures. The key metrics for disaster recovery are recovery time (RTO) and recovery point (RPO). It presents different disaster recovery strategies on a spectrum from backup and restore with high RTO/RPO to multi-site active-active configurations with near real-time RTO/RPO. The document then discusses Crossplane's support for disaster recovery through configuration package upgrades, CRD version rollbacks, and integration with backup tools like Velero. It provides an example disaster recovery scenario restoring databases and Kubernetes clusters across availability zones.
Speed Up Your Kubernetes Upgrades For Your Kafka Clusters
Speed Up Your Kubernetes Upgrades For Your Kafka ClustersVanessa Vuibert Upgrading Kubernetes can be difficult enough without the additional challenge of the petabytes of data associated with your Kafka cluster. At Shopify, we reduced our live Kafka cluster migration time from six months to two weeks by reusing persistent disks. In this talk I’ll explain why we chose this approach, how we did it, and how you can too.
When upgrading Kubernetes it can be preferable to create a new Kubernetes cluster and migrate your workloads instead of performing an in-place upgrade. However, with this approach migrating Kafka to a new Kubernetes cluster over the network can be time consuming.
I will go over how to stretch a Kafka cluster across the old and new Kubernetes clusters without adding any extra brokers. Finally, I will discuss how the Kafka brokers in the new Kubernetes cluster get scaled up while the old one gets decommissioned.

Introduction to helm
Introduction to helmJeeva Chelladhurai Helm is a package manager for Kubernetes that allows for easy installation, upgrade, and management of Kubernetes applications. It provides repeatability, reliability, and simplifies deploying applications across multiple Kubernetes environments. Helm originated from an internal hackathon at Deis and was jointly developed by Google and Deis. It is now maintained by the Cloud Native Computing Foundation. Helm consists of a client that interacts with the Tiller server running inside the Kubernetes cluster to manage application lifecycles using charts, which are packages containing Kubernetes resource definitions.

How did we move the mountain? - Migrating 1 trillion+ messages per day across...HostedbyConfluent Have you ever migrated Kafka clusters from one data center to another being completely transparent to client applications?
At PayPal, as part of a massive datacenter migration initiative, Kafka team successfully moved all PayPal Kafka traffic across data centers. This initiative involved migrating 20+ Kafka clusters (1000+ broker and zookeeper nodes), as well as 60+ mirrormaker groups which seamlessly handle Kafka traffic volumes as high as 1 trillion messages per day. Throughout the course of this migration, applications required no modification, encountered 0% service outage, 0% message loss and duplicated messages. The whole migration process was fully transparent to Kafka applications.
In this session, you will learn the strategies, techniques and tools the PayPal Kafka team has utilized for managing the migration process. You will also learn the lessons and pitfalls they experienced during this exercise, as well as the secret sauce of making the migration successful.

This is especially true for environments where security and governance requirements are so strict as to come into conflict with the cloud-native reference architectures.
This deck will outline a plan that leverages Kubernetes as an infrastructure abstraction (hint: there is a lot more to it than just container orchestration!). Such an approach allows enterprises to untie themselves from infrastructure provider-specific technology stack and free development to use whichever tool fits their use case best. But how do you implement open source cloud-native technologies while meeting enterprise security and governance requirements? We’ll summarize common prerequisites for running Kubernetes in production, and how to leverage fine-grained controls and separation of responsibilities to meet enterprise governance and security needs; what’s needed for a general architecture of a centralized Kubernetes operations layer based on open source components such as Prometheus, Grafana, ELK Stack, Keycloak, etc.

Setting up CI/CD pipeline with Kubernetes and Kublr step-by-step
Setting up CI/CD pipeline with Kubernetes and Kublr step-by-stepOleg Chunikhin This document outlines the steps to set up a CI/CD pipeline with Kubernetes and Kublr. It describes using Kublr to automate the deployment and configuration of Kubernetes clusters. It then discusses setting up the necessary DevOps tools like Jenkins, Nexus, and monitoring within the Kubernetes environment to enable continuous integration and continuous delivery of applications. The general approach involves connecting these tools with a Git repository to build, test, and deploy code changes automatically through the pipeline to development and production clusters.

It provides an overview of Docker, Kubernetes, deploying a sample Clojure service, and configuring GitLab CI for continuous integration and deployment. The sample Clojure service is built as a Docker image, tested using GitLab CI, and deployed to Kubernetes clusters for testing and production using configuration files and GitLab CI pipelines.
Introduction to Kubernetes RBAC
Introduction to Kubernetes RBACKublr Incredibly powerful and flexible, Kubernetes role-based access control (RBAC) is an essential tool to effectively manage production clusters. Yet many Ops and DevOps engineers are still facing barriers to efficiently use it at scale. These include a steep learning curve, YAML-based configuration, lack of standardized best practices, and the general complexity of this functionality at large -- it truly can be somewhat overwhelming.
During this meetup Oleg, CTO at Kublr, will discuss Kubernetes RBAC concepts and objects. He'll explore different use cases ranging from simple permission management for in-cluster application accounts to integrations with external identity providers for SSO and enterprise user access management.
Leveraging the Kublr Platform, Oleg will demonstrate how it simplifies the management of access and RBAC rules in a cloud native environment while staying vendor-independent and compatible with any Kubernetes distribution.

Kubernetes in Hybrid Environments with Submariner
Kubernetes in Hybrid Environments with SubmarinerKublr Submariner enables direct networking between Pods and Services in different Kubernetes clusters, either on-premises or in the cloud.
As Kubernetes gains adoption, teams are finding they must deploy and manage multiple clusters to facilitate features like geo-redundancy, scale, and fault isolation for their applications. With Submariner, your applications and services can span multiple cloud providers, data centers, and regions.
Submariner is completely open source, and designed to be network plugin (CNI) agnostic.
Submariner Provides: cross-cluster L3 connectivity using encrypted VPN tunnels; service Discovery across clusters; subctl, a friendly deployment tool; support for interconnecting clusters with overlapping CIDRs
Hybrid architecture solutions with kubernetes and the cloud native stack
Hybrid architecture solutions with kubernetes and the cloud native stackKublr This presentation provides an overview of how Kubernetes capabilities can be used to simplify use of hybrid infrastructure rather than complicate it. It covers the general challenges posed by hybrid multi-site architectures, including provisioning and operations, ingress traffic management, network connectivity, and distributed data management. The presentation reviews using AWS and Azure as examples how each of these challenges can be addressed with Kubernetes and various Kubernetes controllers used as an infrastructure abstraction layer.
Kubernetes Networking 101
Kubernetes Networking 101Kublr Kubernetes (K8s) is a powerful, flexible and portable open source framework for distributed containerized applications delivery and management. An important part of the services provided by most Kubernetes clusters is the containers’ networking stack. In most cases and for many applications it “just works”, but this seeming simplicity is backed by a complex stack of technologies that provide many capabilities beyond the basics.
This presentation accompanies the meetup and webinar where Oleg Chunikhin, CTO at Kublr, shows how Kubernetes networking stack works, describes main components, interfaces and extensibility options.
What is covered:
- general notions of Kubernetes networking - Pods and Network Policies
- implementation of Kubernetes networking - CNI, CNI plugins, and Linux network namespaces
- some Kubernetes CNI providers: Calico, Weave, Flanel, and Canal
- K8S networking extensibility for advanced and “exotic” use-cases with Multus CNI plugin as an example
Kubernetes persistence 101
Kubernetes persistence 101Kublr In this meetup, Oleg, CTO at Kublr, walks you through the basics of K8s persistence management functionality and how it can be used to simplify managing persistent applications across different environments - in the cloud or on premise. Oleg will use a demo environment with clusters in different clouds to show K8s persistence in practice.
We will cover:
• Persistent data abstractions in K8s: persistent volumes (PV) and their attributes
• PV specifics in different clouds
• Using PV in K8s: persistent volume claims (PVC) and storage classes (SC)
• Automatic volume provisioning
• Persistence and scheduling interrelationships
• Practical examples
Kubernetes (K8s) is a powerful and flexible open source container orchestration system. The power of K8s comes from its modularity and simplicity of basic concepts. Each of these basic concepts build on the other and, from the most basic elements to more advanced ones, each is responsible for its own well-defined logic and behavior.
Kubernetes 101
Kubernetes 101Kublr Kubernetes 101: Intro to Kubernetes namespaces, workloads, and architecture
In this webinar Oleg, CTO at Kublr, will explain the basics of Kubernetes, a powerful and flexible
open-source container orchestration system: what it is, how it works, and the main entities
Kubernetes users work with.
Containers are taking over the IT world, and while building and running them locally is simple,
running them in production on a distributed infrastructure is much more involved.
Oleg will show how Kubernetes can help orchestrating containers across multiple compute
nodes and clouds.
We will cover:
- distributed container orchestration
- architecture of Kubernetes clusters
- important Kubernetes objects: namespaces, pods, services
- overview controllers: deployment, daemonset, stateful set
Advanced Scheduling in Kubernetes
Advanced Scheduling in KubernetesKublr Kubernetes pods / container scheduling 201 - pod and node affinity and anti-affinity, node selectors, taints and tolerations, persistent volumes constraints, scheduler configuration and custom scheduler development and more.
Canary Releases on Kubernetes with Spinnaker, Istio, & Prometheus (2020)
Canary Releases on Kubernetes with Spinnaker, Istio, & Prometheus (2020)Kublr In a microservices world, applications consist of dozens, hundreds, or even thousands of components. Manually deploying and verifying deployment quality in production is virtually impossible. Kubernetes, which natively supports rolling updates, enables blue-green application deployments with Spinnaker. However, the gradual rollout is a feature that doesn’t come out-of-the-box but can be achieved by adding Istio and Prometheus to the equation.
During this meetup, Slava will discuss canary release implementations on Kubernetes with Spinnaker, Istio, and Prometheus. He’ll examine the role of each tool in the process and how they are all connected. During a demo, he will demonstrate a successful and failed canary release, and how these tools enable IT teams, to properly roll out changes to their customer base without any downtime.
Building Portable Applications with Kubernetes
Building Portable Applications with KubernetesKublr Containers and Kubernetes enable code portability across on-premise VMs, bare metal, or multiple clouds. However, many developers may include configuration and application definitions that constrain or even eliminate application portability.
We'll outline best practices for “configuration as code” in a Kubernetes environment. He'll demonstrate how a properly constructed containerized app can be deployed to both Amazon and Azure using the Kublr platform, and how Kubernetes objects, such as persistent volumes, ingress rules, and services, can be leveraged to abstract from the infrastructure.
How Self-Healing Nodes and Infrastructure Management Impact Reliability
How Self-Healing Nodes and Infrastructure Management Impact ReliabilityKublr Self-healing does not equal self-healing. There are multiple layers to it, whether a self-healing infrastructure, cluster, pods, or Kubernetes. Kubernetes itself ensures self-healing pods. But how do you ensure your applications, whose reliability depends on every single layer, are truly reliable?
This presentation covers the different self-healing layers, what Kubernetes does and doesn't do (at least not by default), and what you should look out for to ensure true reliable applications. Hint: infrastructure provisioning plays a key role.
Kubernetes in Highly Restrictive Environments
Kubernetes in Highly Restrictive EnvironmentsKublr Installing Kubernetes is easy. Ensuring it complies with your organization’s enterprise governance and security requirements isn’t.
How do you use the technologies while meeting enterprise security requirements? We'll summarize common prerequisites for running Kubernetes in production, and how to leverage fine-grained controls and separation of responsibilities to meet enterprise governance and security needs.
This deck includes basic requirements for audit, security, authentication, authorization, integration with existing identity broker, logging, and monitoring. Additionally, we'll go into whether cloud-hosted Kubernetes cover these requirements, how to integrate a compliant Kubernetes installation with their existing cloud infrastructure and how to handle cross-team communication (network/compute/storage/security).
Since on-premise Kubernetes deployments have their challenges, limitations of a bare-metal installation, interactions with vSphere’s API, achieving HA, reliability and disaster recovery, as well as handling OS upgrades, security patches, and Kubernetes upgrades are also considered.

Kubernetes data science and machine learning
Kubernetes data science and machine learningKublr Enabling support for data processing, data analytics, and machine learning workloads in Kubernetes has been one of the goals of the open source community. During this online meetup we discussed the growing use of Kubernetes for data science and machine learning workloads. We examined how new Kubernetes extensibility features such as custom resources and custom controllers are used for applications and frameworks integration. Apache Spark 2.3.’s native support is the latest indication of this growing trend. We demoed a few examples of data science workloads running on Kubernetes clusters setup by our Kublr platform
Implement Advanced Scheduling Techniques in Kubernetes 
Implement Advanced Scheduling Techniques in Kubernetes Kublr
Is advanced scheduling in Kubernetes achievable? Yes, however, how do you properly accommodate every real-life scenario that a Kubernetes user might encounter? How do you leverage advanced scheduling techniques to shape and describe each scenario in easy-to-use rules and configurations?
Oleg Chunikhin addressed those questions and demonstrated techniques for implementing advanced scheduling. For example, using spot instances and cost-effective resources on AWS, coupled with the ability to deliver a minimum set of functionalities that cover the majority of needs – without configuration complexity. You’ll get a run-down of the pitfalls and things to keep in mind for this route.
Application Portability with Kubernetes (k8)
Application Portability with Kubernetes (k8)Kublr Containers and Kubernetes allow for code portability across on-premise VMs, bare metal or multiple cloud provider environments. Yet, despite this portability promise, developers may include configuration and application definitions that constrain or even eliminate application portability. In this meetup Oleg Chunikhin, CTO at Kublr, described best practices for “configuration as code” in a Kubernetes environment. He demonstrated how a properly constructed containerized app can be deployed to both Amazon and Azure using the Kublr platform, and how Kubernetes objects, such as persistent volumes, ingress rules and services, can be used to abstract from the infrastructure.

Who Watches the Watchmen (SciFiDevCon 2025)
Who Watches the Watchmen (SciFiDevCon 2025)Allon Mureinik Tests, especially unit tests, are the developers’ superheroes. They allow us to mess around with our code and keep us safe.
We often trust them with the safety of our codebase, but how do we know that we should? How do we know that this trust is well-deserved?
Enter mutation testing – by intentionally injecting harmful mutations into our code and seeing if they are caught by the tests, we can evaluate the quality of the safety net they provide. By watching the watchmen, we can make sure our tests really protect us, and we aren’t just green-washing our IDEs to a false sense of security.

Exceptional Behaviors: How Frequently Are They Tested? (AST 2025)
Exceptional Behaviors: How Frequently Are They Tested? (AST 2025)Andre Hora Exceptions allow developers to handle error cases expected to occur infrequently. Ideally, good test suites should test both normal and exceptional behaviors to catch more bugs and avoid regressions. While current research analyzes exceptions that propagate to tests, it does not explore other exceptions that do not reach the tests. In this paper, we provide an empirical study to explore how frequently exceptional behaviors are tested in real-world systems. We consider both exceptions that propagate to tests and the ones that do not reach the tests. For this purpose, we run an instrumented version of test suites, monitor their execution, and collect information about the exceptions raised at runtime. We analyze the test suites of 25 Python systems, covering 5,372 executed methods, 17.9M calls, and 1.4M raised exceptions. We find that 21.4% of the executed methods do raise exceptions at runtime. In methods that raise exceptions, on the median, 1 in 10 calls exercise exceptional behaviors. Close to 80% of the methods that raise exceptions do so infrequently, but about 20% raise exceptions more frequently. Finally, we provide implications for researchers and practitioners. We suggest developing novel tools to support exercising exceptional behaviors and refactoring expensive try/except blocks. We also call attention to the fact that exception-raising behaviors are not necessarily “abnormal” or rare.
