Running and Managing Kubernetes on OpenStackVictor Palma

OpenStack on Kubernetes (BOS Summit / May 2017 update)rhirschfeld

This document discusses using Kubernetes as an underlay platform for OpenStack. Some key points: 1. Kubernetes is becoming more widely used and understood by operators compared to OpenStack. Using Kubernetes as an underlay could improve simplicity, stability, and upgrade processes for OpenStack. 2. There are still many technical challenges to address, such as networking, storage, tooling to manage OpenStack on Kubernetes, and ensuring containers meet Kubernetes' immutable infrastructure requirements. 3. Using Kubernetes as an underlay risks further confusing the messaging around OpenStack by implying Kubernetes is more stable or a replacement target. Clear communication will be important to avoid undermining OpenStack.

Kubernetes and OpenStack at ScaleStephen Gordon

Kubernetes and OpenStack at Scale at OpenStack Summit Boston 2017 Imagine being able to stand up thousands of tenants with thousands of apps, running thousands of Docker-formatted container images and routes, all on a self-healing cluster and elastic infrastructure. Now, take that one step further - all of those images being updatable through a single upload to the registry, and with zero downtime. In this session, you will see just that. In this presentation, we will walk through a recent benchmarking deployment using Kubernetes and OpenStack on the Cloud Native Computing Foundation’s (CNCF's) 1,000 node cluster with OpenStack and Red Hat’s OpenShift Container Platform, the enterprise-ready Kubernetes for developers. You'll also what's been happening in subsequent rounds of testing in Red Hat's own SCALE lab and the CNCF cluster and how we are working with the relevant open source communities including OpenStack, Kubernetes, and Ansible to continue to raise the bar for horizontal scaling of these platforms via community powered innovation.

Kubernetes - A Short Ride Throught the project and its ecosystemMaciej Kwiek

Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. It groups related containers together and manages the deployment of these container pods across clusters of physical or virtual machines. Kubernetes has master components that control the cluster and node components that run on each machine in the cluster. It uses pods as the basic building block and schedules the pods across nodes to provide high availability and easy management of applications.

"Kubernetes as Driver of Generic IT Automation"ConSol Consulting & Solutions Software GmbH

Kubernetes as a platform is moving fast from being the "new IT" to standing right in the center of most companies infrastructure. What does that mean for IT Automation? For its own purposes, Kubernetes already comes with a well-engineered declarative model of managing computing resources that has proven to be very efficient. In classic IT, likewise proven automation solutions like Red Hat Ansible are established. This forms two automation silos, and as we all know: Silos are a bad thing. Is there a way to bridge this gap? In this session we will highlight the possibilities to use Kubernetes state management as backbone for IT automation by extending it with custom operators using Red Hat Ansible. Ansible with its focus on idempotency is a really great match for implementing Kubernetes-Operators and doing it to automate non-K8s resources, just like you would do with Ansible Tower, is easier than you might think. We will have a look at different use cases and provide a strategic outlook.

Cloud Device InsecurityJeremy Brown

Your data is much safer at home than it is letting some corporation "take care of it" for you, right? Security reviews for some of the top vendors' devices reveal many interesting findings. Like everything else, there are bugs. But knowing what kinds of bugs and how the vendors have responded will allow you to better understand the impact of plugging these devices into your network. Jeremy will show you just how low access control and least privilege are their list of priorities. He'll also explore the amount of test collateral and debug interfaces sloppily left shipping to consumers. From remote roots to stealing social network tokens to just plain weird stuff, he'll expand on how it's not just about what they do, but also what they don't do. And, he'll give you some useful guidelines on how to close the gaps yourself.

TrustArc Webinar: Consumer Expectations vs Corporate Realities on Data Broker...TrustArc

Most consumers believe they’re making informed decisions about their personal data—adjusting privacy settings, blocking trackers, and opting out where they can. However, our new research reveals that while awareness is high, taking meaningful action is still lacking. On the corporate side, many organizations report strong policies for managing third-party data and consumer consent yet fall short when it comes to consistency, accountability and transparency. This session will explore the research findings from TrustArc’s Privacy Pulse Survey, examining consumer attitudes toward personal data collection and practical suggestions for corporate practices around purchasing third-party data. Attendees will learn: - Consumer awareness around data brokers and what consumers are doing to limit data collection - How businesses assess third-party vendors and their consent management operations - Where business preparedness needs improvement - What these trends mean for the future of privacy governance and public trust This discussion is essential for privacy, risk, and compliance professionals who want to ground their strategies in current data and prepare for what’s next in the privacy landscape.

DevOpsDays Atlanta 2025 - Building 10x Development Organizations.pptxJustin Reock

Building 10x Organizations with Modern Productivity Metrics 10x developers may be a myth, but 10x organizations are very real, as proven by the influential study performed in the 1980s, ‘The Coding War Games.’ Right now, here in early 2025, we seem to be experiencing YAPP (Yet Another Productivity Philosophy), and that philosophy is converging on developer experience. It seems that with every new method we invent for the delivery of products, whether physical or virtual, we reinvent productivity philosophies to go alongside them. But which of these approaches actually work? DORA? SPACE? DevEx? What should we invest in and create urgency behind today, so that we don’t find ourselves having the same discussion again in a decade?
