Deploying & Scaling OpenShift on OpenStack using Heat - OpenStack Seattle MeetUp 2014-01-23 by Diane Mueller @pythondj

Published on

OpenShift Origin is an open-source Platform-as-a-Service project sponsored by Red Hat. In this session, Diane will be discussingOpenShift's use of Heat to deploy OpenShift on OpenStack showcase a number of aspects of configuring and managing a complex application on OpenStack’s Diskimage-builder and OpenStack’s Heat, both tools are bundled with RHOS 4.

Diane will walk thru the basic architecture of the application being deployed (OpenShift), then discuss how to configure OpenStack Neutron networking for OpenShift, register images with Glance, monitor Heat, and then show how to point OpenShift command line client to the broker's public ip address and begin using OpenShift.

All the heat templates used are available here:https://github.com/openstack/heat-templates and this is an awesome way to learn about Heat and contribute to both the OpenShift & OpenStack communities.

  • What if you could use existing infractructure (bare metal or virtualized), private cloud, and public cloud in one, unified environment?
    Open hybrid cloud lets you take advantage of your existing resources, and be open to new advances. Build a cloud infrastructure that’s easy to integrate, agile, and future-proof.
    UNIVERSAL (UNIFIED?) ENVIRONMENT: An environment that is ready any time, all the time. Because it’s built with technology that is standardized, interoperable, and modular.
    This allows you to reuse the infrastructure you have to build more agile enterprise I.T.
  • A bit about Heat: The Heat API implements the AWS Cloud Formations API. This API provides a rest interface for creating composite VMs called Stacks from template files. The goal of the software is to be able to accurately launch AWS CloudFormation Stacks on OpenStack. We will also enable good quality high availability based upon the technologies we created in Pacemaker Cloud including escalation.

    4 trends according to Werner
    Cloud will enable your content to follow you wherever you go
    Cloud has changed how we interact with mobile devices. In the past content would be moved to the device, now devices are just a window to content and services that live in the cloud. This started with our smartphones and tablets, where regardless of which device we use, or the location, we have access to our content and subscriptions.
    Now this approach is migrating to non-mobile devices such as Samsung smart TV's. The devices are beautifully designed and beautifully built, but the core functionally of these television sets is software connected to services running in the cloud.
    This is also moving beyond traditional devices, for example my car is already connected to my Amazon Cloudplayer giving me music everywhere I go. I have seen the first treadmills where the moment I step on them they reconfigure to give access to my music and videos, my newspaper subscriptions and books, but also my documents in services like Dropbox. I no longer need to bring my content; cloud enables my content to follow me wherever I go.
    Cloud based analytics enhances the offline world
    The cloud is already the place where researchers collaborate on data that flows in real-time from devices such as the Mars rover or the Ilumina DNA sequencer into cloud storage. In 2014 expect an explosion in data generation by real-world devices and where that data is stored, analysed and shared in the cloud.
    For example we will see a rise in the industrial cloud where industrial environments are equipped with sensors producing data to improve efficiency and reliability. An example is the project we run with GE on instrumenting their gas turbines or with Shell where they are going to drop sensors in their oil wells that generate petabytes of data.
    Also in our daily lives we will see the rise of cloud connected sensors and devices such as the Nest Thermostat or the home control applications built by energy companies like Essent. Around the world public transport companies are instrumenting their busses and trams with sensors that feed into platforms like OneBusAway that can give real-time updates to travellers.
    Passengers themselves can also become sensors: services like Mooveit use the information from an application on passengers' phones to give real time transport information in the same way that Waze does for cars.
    The cloud allows everyone to become a media company
    In 2014 expect a great rise in organisations that are adding media capabilities to their offerings. A good example is sports clubs; all are looking for ways to establish an engagement with their fan base beyond the two hours on a weekend. A successful way to achieve a weeklong engagement is by daily distribution or fresh, exclusive media content. The subscription revenues for clubs that often have millions of fans around the world are substantial.
    Cloud based services for pre and post production, as well as distribution, are readily available such that anyone can become an internet broadcaster operating worldwide without any capital investment. A well-known case is that of the Amazon Web Services (AWS) powered LiverpoolTV, but every football club worldwide is following their example.
    Another very popular case is that of performing arts organisations, from orchestras to theatre companies, which give exclusive access to their performances through cloud-based media production. This way they are able to reach a much larger audience, which would often not be able to attend their performances in person. It extends their revenue potential, which is needed in times where arts subsidies are disappearing. A good example is Berliner Philharmoniker, the world famous orchestra that gives access to their live performances through the digitalconcerthall.com that makes use of all AWS regions around the world to provide a high quality media experience.
    Faster and faster, cloud moves data processing to real-time
    Up until this point big data has very much focused on looking historically - people who brought product X also brought product Y, the market moved in this direction last week so is likely to move in that direction now. There has always been a close relationship between big data and cloud computing as it requires no limits in terms of compute and storage but by adding real-time processing capabilities, we will see a rise in data analytics that are able to produce results for in real-time, radically changing the products companies can build.
    For example we see companies with real time recommendations, in the form of 'other people in your network are reading X'. Some of the frontrunners here are the companies working on second-screen technologies, such as Channel 4, that make use of real-time data to power the information they present to augment TV watching. A company like Netflix that processes over 40bn events a day uses real-time analytics to power their operations, their customer engagement and their business metrics.
    We see almost every industry taking advantage of the cloud to radically improve the speed at which they can process their data.

  • For either the Entrepreneurial or the Enterprise Developer, PaaS is the way of the future.
    Let's take a quick look at the before-and-after of the application development process.
    In the old days, when you wanted to build a new app (or were assigned a project to build a new app), you had to jump through a million hoops to get it up and running. Everything from ordering hardware, to installing middleware, to tuning and testing every facet of the development environment.
    With PaaS, life is much easier. You have an idea for an application? You just start writing the code and let OpenShift PaaS handle the rest.
    Write your code, Push to OpenShift, Test with Jenkins, and Deploy when ready!
    Even Gartner knows that PaaS will be the way of the future for application development.

    So, what you need is the ease of use and access of a SaaS application, but you need it with your purpose-built, mission-critical, applications.
    PaaS gives you just that. It allows you to quickly and easily build the application that YOU need. Whether this is for your group, your enterprise, or your next BIG IDEA, you can build it and launch your specific code on a PaaS and not have to deal with the underlying infrastructure, middleware, and management headaches.
    Because of the built-in auto-scaling and elasticity provided by the PaaS infrastructure, PaaS's are ideal for modern data-hungry Big Data, Mobile, and Social applications.
    With a PaaS, you can focus on what you should be focused on... your application code.
    And let the Cloud provide what it is suppose to: Ease, Scale and Power
