PRESENTED AT OPENSTACK SUMMIT - BARCELONA 2016
With test driven development, continuous integration/continuous deployment and devops practices now the norm, most organizations understand the importance of testing their applications. But what about the cloud those applications are going to live on? Too many companies miss this critical step, leading to gaps in their operations, which can lead to production issues, API outages, inability to upgrade, and general instability of the cloud. It all begs the question: “Do you even test?" During this session, attendees will learn how Rackspace leverages Red Hat’s Distributed Continuous Integration (DCI) to build a better OpenStack experience for their customers while reducing the time required to not only roll out the latest version of OpenStack to new customers, but also begin upgrading customers within weeks of announcement. In addition to this, the automated testing in DCI raises bugs directly with Red Hat QEs team to shorten the feedback cycle and improve the final product.
Test your Kubernetes operator with Operator Lifecycle ManagementBaiju Muthukadan
Operator pattern is pioneered by CoreOS, and it is embraced by the Kubernetes community. The Operator framework from CoreOS/Red Hat is also getting adoption.

Technical Director, MongoDB
MongoDB Ops Manager is an enterprise-grade end-to-end database management, monitoring, and backup solution. Kubernetes has clearly won the orchestration-platform "wars". In this session we'll take a deep dive on how you can leverage both these technologies to host your MongoDB deployments within your Kubernetes infrastructure whether that's OpenShift, PKS, Azure AKS, or just upstream. This talk will review the core technologies, such as containers, Kubernetes, and MongoDB Ops Manager. You'll also have a chance to see real-live demos of MongoDB running on Kubernetes and managed with MongoDB Ops Manager with the MongoDB Enterprise Kubernetes Operator.
Replicating production on your laptop using the magic of containers v2Jamie Coleman
Containers are an amazing technology that is revolutionising how we do computing in the modern age. 5 years ago, people were starting to use Docker and realising the potential that container technology could offer. Now every major cloud provider offers a container service with the addition of container orchestrator like Kubernetes that millions of developers around the world are starting to use. Now many of our applications are running in containers why not use that magical portable configuration that containers offer to replicate our production environments locally on our laptops… enter MicroShed and the Testcontainers frameworks. Testcontainers run and test with true-to-production environments in development with minimal re-writing of your test code giving you more time as a developer to write your application. This talk will give you a great overview of the technology and will demo how simple it is to create and run a MicroShed test in Maven.

Profile your Java apps in production on Red Hat OpenShift with Cryostat | Dev...Red Hat Developers
Did you know that OpenJDK comes with Java Flight Recorder (JFR), an embedded production time profiler? Cryostat provides easy and secure access to JFR across container boundaries so you can profile that performance bottleneck, or find that annoying bug. Join this session to learn about using Cryostat to profile Java applications in production on OpenShift.
Cloud native applications are popular these days – applications that run in the cloud reliably und scale almost arbitrarily. They follow three key principles: They are built and composed as microservices, they are packaged and distributed in containers and the containers are executed dynamically in the cloud. In this hands-on session we will show how to build, package and deploy cloud native Java EE applications on top of DC/OS - fully automated with Gradle using cloud native infrastructure like Consul, Fabio, Hystrix and Prometheus. And for the fun of it we will be using an off-the-shelf DJ pad, programmed with nothing else than the Java Sound API, to demonstrate the core concepts and to visualize and remote control DC/OS.

== Please download slides if blurred! ==
Abstract:
Continuous delivery is everywhere. Well, not quite! Many teams still fail to continuously deliver well tested and stable product increments to production, especially when it comes to its non-functional attributes. Usually with the same old excuse: these high-level tests are too laborious and expensive to implement. But the opposite could be the case! This slides will show how easy it is to implement continuous performance, security and acceptance tests based for microservices on Kubernetes using well-known open source tools.

Master a Cloud Native Standard - MicroProfile.pptxEmilyJiang23
Everything about MicroProfile, a Cloud Native Application Development Standard. This help you develop a portable microservice without vendor lockin and works well in the Cloud.
Codecamp 2020 microservices made easy workshopJamie Coleman
Ever wondered what makes a cloud-native application “cloud-native”? Ever wondered what the unique challenges are and how best to address them on fully-open Java technologies? In this workshop, you’ll learn what it means to be cloud-native and how that impacts application development. You’ll learn about Eclipse MicroProfile, an industry collaboration defining technologies for the development and management of cloud-native microservices. With a full set of MicroProfile workshop modules available to you, you’ll be able to start with the basics of REST services and progress to more advanced topics, or you can jump right in and develop secure, fault tolerant, configurable and monitorable microservices.
Once you’ve developed your microservice, you’ll learn how to package it in a Docker container and deploy it to a Kubernetes cluster. Finally, you’ll learn the role of a service mesh and use Istio to manage your microservice interactions or you can choose to deploy your microservices to OpenShift.
Cloud Native Night, April 2018, Mainz: Workshop led by Jörg Schad (@joerg_schad, Technical Community Lead / Developer at Mesosphere)
Join our Meetup: https://www.meetup.com/de-DE/Cloud-Native-Night/
PLEASE NOTE:
During this workshop, Jörg showed many demos and the audience could participate on their laptops. Unfortunately, we can't provide these demos. Nevertheless, Jörg's slides give a deep dive into the topic.
DETAILS ABOUT THE WORKSHOP:
Kubernetes has been one of the topics in 2017 and will probably remain so in 2018. In this hands-on technical workshop you will learn how best to deploy, operate and scale Kubernetes clusters from one to hundreds of nodes using DC/OS. You will learn how to integrate and run Kubernetes alongside traditional applications and fast data services of your choice (e.g. Apache Cassandra, Apache Kafka, Apache Spark, TensorFlow and more) on any infrastructure.
This workshop best suits operators focussed on keeping their apps and services up and running in production and developers focussed on quickly delivering internal and customer facing apps into production.
You will learn how to:
- Introduction to Kubernetes and DC/OS (including the differences between both)
- Deploy Kubernetes on DC/OS in a secure, highly available, and fault-tolerant manner
- Solve operational challenges of running a large/multiple Kubernetes cluster
- One-click deploy big data stateful and stateless services alongside a Kubernetes cluster
In this WebHack talk I shared my experience about microservices, Docker, Kubernetes and Kong, an API gateway by Mashape. Since they are based on a real working system, this slides is majorly for how to build the whole thing up, not about detailed internal implementation. Although I included some details and reference in order to make it more comprehensive.

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.
Graspan: A Big Data System for Big Code AnalysisAftab Hussain
We built a disk-based parallel graph system, Graspan, that uses a novel edge-pair centric computation model to compute dynamic transitive closures on very large program graphs.
We implement context-sensitive pointer/alias and dataflow analyses on Graspan. An evaluation of these analyses on large codebases such as Linux shows that their Graspan implementations scale to millions of lines of code and are much simpler than their original implementations.
These analyses were used to augment the existing checkers; these augmented checkers found 132 new NULL pointer bugs and 1308 unnecessary NULL tests in Linux 4.4.0-rc5, PostgreSQL 8.3.9, and Apache httpd 2.2.18.
