Modernizing application deployments with OpenShift Container Platform

Red Hat Developer Program

Ryan Hennessy, Sr. Solution Architect, Red Hat and Guna Vijayaratnam, Solutions Architect, Red Hat speak in this breakout session at Red Hat Summit 2017. The Red Hat team had the opportunity to work with a lot of customers, this one, in particular, was struggling with their application deployment process. Their current processes were fragile and didn’t meet the business needs to be more flexible, automated, and cloud-centric. The customer IT department realized if they didn’t address these problems soon there was a high risk that individual business units were going to start looking to other partners for serving their IT needs. In this session, we will cover in depth the following areas: Main hosting focus areas and business drivers that lead to the adoption of OpenShift Application delivery methodologies that were modernized using OpenShift How OpenShift was able to directly solve the challenges and focus areas set out by IT leadership. https://www.redhat.com/en/summit/2017/agenda/sessions

Mastering deployments with Kubernetes & OpenShift Video

Red Hat Developer Program

Hear from Rafael Benevides, Director of Developer Experience at Red Hat in this breakout session at Red Hat Summit 2017. The "deploy moment" is an occasion that still causes many developers to shiver. But it shouldn't be this way, at least not every time. Deployment failures, customer downtime, hundreds of calls to customer service—we've all been there. Luckily, today we have the tools and processes to turn the deploy moment into just another ordinary activity. In this session, we'll show you how to evolve your deployment process from the very basic zero downtime with some very interesting additional strategies such as blue/green, A/B, and canary deployments. You'll learn how to not only deploy your software faster, with a vastly better uptime, but how to use container technologies like OpenShift to get business feedback—and recover some well-deserved sleep time. https://www.redhat.com/en/summit/2017/agenda/sessions

Microservices with Kubernetes, Docker, and Jenkins (Rafael Benevides, Christian Posta)

Red Hat Developer Program

A lot of functionality necessary for running in a microservices architecture have been built into Kubernetes; why would you re-invent the wheel with lots of complicated client-side libraries? Have you ever asked why you should use containers and what are the benefits for your application? This talk will present a microservices application that have been built using different Java platforms: WildFly Swarm and Eclipse Vert.x. Then we will deploy this application in a Kubernetes cluster to present the advantages of containers for MSA (Microservices Architectures) and DevOps. The attendees will learn how to create, edit, build, deploy Java Microservices, and also how to perform service discovery, rolling updates, persistent volumes and much more. Finally we will fix a bug and see how a CI/CD Pipeline automates the process and reduces the deployment time.

Kubernetes for Java Developers (Edson Yanaga, Rafael Benevides)

Red Hat Developer Program

Yes, Docker is great. We are all very aware of that, but now it’s time to take the next step: wrapping it all and deploying to a production environment. For this scenario, we need something more. For that “more,” we have Kubernetes by Google, a container platform based on the same technology used to deploy billions of containers per month on Google’s infrastructure. Ready to leverage your Docker skills and package your current Java app (WAR, EAR, or JAR)? Come to this session to see how your current Docker skill set can be easily mapped to Kubernetes concepts and commands. And get ready to deploy your containers in production.

Openshift Enterprise 3 Walk-Through With Docker And Kubernetes (Grant Shipley)

Red Hat Developer Program

Everyone's heard about Docker and how it's going to solve all of our problems, or not. In this session, we'll walk you through using Docker and discuss why using a scheduler and orchestration system is important. Then we'll dive into an actual usage of the container application platform, OpenShift Enterprise 3 by Red Hat, to show how it makes both Docker and Kubernetes accessible to the average human being. We'll keep the slides to a minimum and instead focus on live demo/coding/deployments. After deploying several containers, we'll turn up the heat by showcasing scaling and moving on to deployment strategies including blue/green.

Scaling In-Memory Data Grid Automatically With Kubernetes (Ray Tsang)

Red Hat Developer Program

Kubernetes is a powerful, open source, container orchestration and cluster management tool from Google. It drew upon all the lessons learned from a near-decade of using containers at Google. In this session, we'll look beyond container orchestration with Kubernetes and take a deep dive into more advanced features such as autoscaling. But its most powerful feature is its versatile REST API, which you can use to tailor Kubernetes to your needs. In addition to the out-of-the-box Kubernetes Autoscaler, we'll look at: - How to access the Kubernetes API securely - The different Kubernetes resources such as Pod, Replication Controller, Service, etc. - How to update/manage your entire cluster using the API We'll use the techniques and the REST API to demonstrate how to cluster Infinispan, an in-memory data grid, in Kubernetes, and autoscale Infinispan using custom metrics.

Putting The 'M' In MBaaS (Jay Balunas)

Red Hat Developer Program

When you hear the term "MBaaS," or "Red Hat Mobile," there is usually a lot of discussion about powerful scaling, back-end integrations, hosting options, containerization, etc. However, we can't forget what that "M" stands for, and why the platforms exist in the first place, which is to develop and deliver top-notch mobile applications to your users. In this session, we'll review what makes all of this possible—client SDKs, hybrid solutions like Cordova, and Xamarin, and our own Build Farm and Unified Push server. Not stopping there, our AppForms support makes it a snap to tie in back-end systems all the way to your app. And this is all backed by various templates, guides, and new open source resources that will help you get started and join the fun.

Fabric8-Ing Continuous Improvement - Kubernetes/Jenkins Pipeline (James Rawlings & James Strachan)

Red Hat Developer Program

Using Docker for building and packaging small discrete microservices, and Kubernetes to ensure they stay running and gaining OOTB service discovery, significantly reduces the challenges of having a consistent way to build, package, and run applications. Then, there's how to develop, test, promote, release, support, and improve our container-based architectures, taking an idea from inception to repeatable releasing in a live environment. In this session, we'll look at how fabric8, which runs on top of OpenShift 3 by Red Hat and Kubernetes, uses Docker and Jenkins workflow for pipeline orchestration to provide an extensible OOTB CD solution. Fabric8 significantly simplifies the creation of new projects with a one-click setup and the wiring-together of tooling such and version control systems, artifact repositories, and release pipelines. With human approval, automated integration testing, ChatOps, environment + pipeline visualisation, commit traceability, and a developer experience that helps teams deliver value faster, we'll see how the strength of the open source community works together to provide a consistent approach to building and releasing software for new, cloud-based microservices.
