Build Your Own PaaS, Just like Red Hat's OpenShift from LinuxCon 2013 New Orleans CloudOpen Build Your Own PaaS, Just like Red Hat's OpenShift from LinuxCon 2013 New Orleans CloudOpen Presentation Transcript

  • Build Your Own PaaS, Just Like Red Hat's OpenShift Diane Mueller dmueller@redhat.com Cloud Ecosystem Evangelist & Origin Community Manager dmueller@redhat.com Twitter: @pythondj http://openshift.github.io
  • 2 Agenda ● Cloud Vision @ RedHat ● Why PaaS Matters ● What is OpenShift? ● OpenShift Architecture & Internals ● Extending OpenShift with Cartridges ● How do you like your PaaS? ● The Road Ahead ● HP & Red Hat Collaboration
  • 5
  • 6 How to Build an App Old School vs. Today with PaaS
  • 7 PaaS is the Future *http://www.gartner.com/technology/research/cloud-computing/report/paas-cloud.jsp
  • 8 Focus is still on delivering Cloud Infrastructure
  • 9 and managing expectations in the Cloud
  • 10 New Cloud World Order
  • 11 Infrastructure as a Service gives you • Network, storage & compute as an on-demand service • Basically, servers in the cloud • You’re still on the hook to configure & manage the cloud & stack “How do I use this?”
  • 12 Software as a Service gives you • An on-demand application • Nothing to install or configure “This is all my customers and users care about!”
  • 13 Platform as a Service delivers • Application run-time environment in the cloud • Configures & manages both the cloud & stack for your application “The cloud is now useful!”
  • 14 What is OpenShift? ` The Next Generation Open Source Platform as a Service for Applications in the Cloud
  • 15 origin Public Cloud Service On- premise or Private Cloud Software Open Source Project FLAVORS OF OPENSHIFT
  • 16 OpenShift Online (http://openshift.com)
  • 17 We're not the only ones using OpenShift ● On Premise Private Clouds ● Public Clouds – For Enterprises – For SaaS providers – For Developers ● Other Public PaaSes Https://github.com/getupcloud/origin-server
  • 18 OpenShift Origin on Github http://openshift.github.io/
  • 19 OpenShift Enterprise ENTERPRISE IT MANAGED ● Let developers have the benefits of self-service PaaS while IT retains control for governance and compliance in a Private or Hybrid Cloud ● OpenShift Enterprise is designed to be deployed on top of and run on Red Hat Enterprise Linux (RHEL).
  • 20 What makes OpenShift different? ● RHEL Platform Support ● SELinux-based Secure Containers for multi-tenancy ● Extensible Architecture ● System Component Redundancy for High Availability ● Automatic Application Stack Provisioning ● Support for Java EE 6 ● Choice of Cloud Infrastructure, Bare Metal, or Desktop ● Configurable Deployment to Support Enterprise Requirements ● Automatic Application Scaling
  • 21
  • 22 http://openshift.github.io/
  • 23
  • 24 Multiple, Diverse, Complex Application Use Cases ● Require more than just “Infrastructure” ● Run on a diverse eco-system of application stacks ● Need to be secure, compliant and well-managed ● Scale or Fail
  • 25 Infrastructure Layer SaaS/Applications Layer Infrastructure LayerInfrastructure Layer Platform as a Service fills out the Cloud Layer Cake
  • 26 Infrastructure Layer SaaS/Applications Layer Infrastructure LayerInfrastructure Layer Extend OpenShift with Cartridges
  • 27 ● Expectation Management ● Add a PaaS Layer to your Cloud – Increases Interoperability – Adds On-Demand, Self Service – (Security+Privacy+Control ) = Compliance PaaS Languages, frameworks, web servers Services: Data, Messaging, others IaaS Hypervisor/Infrastructure
  • 28 OpenShift Architecture & Internals
  • 29 Summary of Key Terms Broker – Management host, orchestration of Nodes Node – Compute host containing Gears Gear – Allocation of fxed memory, compute, and storage resources for running applications Cartridge – A technology/framework (PHP, Perl, Java/JEE, Ruby, Python, MySQL, etc.) to build applications Application – Instantiation of a Cartridge 29
  • 3030 Amazon EC2 Rackspace Bare Metal OpenStack RHEV CloudStack OpenShift Origin PaaS Runs on IaaS
  • 3131 OpenShift Origin Machines Node Broker Broker Broker Node Nodes are where User applications live. An OpenShift Origin Broker can manage multiple nodes
  • 3232 Broker
  • 3333 Container Architecture Gear Node Gear Gear Gear CPU/Memory - C-Groups Network - IPTables / Traffic control policies Filesystem - Quota Security - Unix permissions + SELinux policies Filesystem - pam_namespace + Bind mounts

  • 42 • Database • Language • Daemon • Load-balancer • Key-value store 42 ... on OpenShift I want to run a ...
  • 43 •Ability to act on cartridge lifecycle events •Expose HTTP/Web-socket ports •Run your own binaries •Communicate with other instances •Create configuration files •Access and create to environment variables •Act on user specifies modes of operation •Provide user a starting point 43 Cartridge API
  • 44 More Complex Examples 44 • http://tinyurl.com/online-cartridges • JBoss EWS: • multiple versions of packaged software • support for multiple java versions • MySQL • pub/sub database connections • PHP My Admin • one cartridge dependent on another
  • Deploying your own OpenShift where you want it when you want it! We have a pre-built VM for you to check out today, and an installer is in the works for Origin 3.0 that will enable you to install Origin on your own systems or confgure multiple Origin VMs into a distributed PaaS
  • 46 How do you you like your PaaS? http://openshift.github.io/documentation/oo_deployment_guide_puppet.html https://mirror.openshift.com/pub/origin-server/release/2/images/openshift-origin.zip

  • 51 51 Amazon EC2 Rackspace Bare Metal OpenStack RHEV CloudStack OpenShift Origin PaaS OpenShift Runs on IaaS https://github.com/openshift/origin-dev-tools
  • 52 OpenShift on OpenStack
  • 53 OpenShift on OpenStack with Heat ● Disk Image Builder – to build the image ● Heat – to orchestrate the resources ● OpenStack – to run the infrastructure
  • 54 Disk Image Builder ● Produces images for a specific purpose ● Uses a chroot and bind mounted /proc /sys /dev ● Uses “elements” to alter how the image is built ● Supports Ubuntu, Fedora, RHEL
  • 55 Heat ● An orchestration service to build multiple composite cloud applications ● Uses AWS CloudFormation template format ● Interacts with OpenStack using native ReST API to create infrastructure resources – Instances, foating ips, volumes, security groups, users, etc
  • 56 Heat References ● http://github.com/openstack/heat ● http://github.com/openstack/diskimage-builder ● http://wiki.openstack.org/wiki/Heat
  • The Road Ahead It's all about Collaboration & Community
