  11. The OpenStack Project Ecosystem (Folsom > Grizzly)

  12. * Pre-July 2010 is predicated by Rackspace Cloud Files project (Swift), NASA Nebula project (Nova) OpenStack Ecosystem / History

  13. OpenStack Project Lifecycle Open Discussion – request assistance from OpenStack contributors to add lifecycle detail Ironic project as an example: October 2013 Hong Kong Havana / Icehouse Summit April 2013 Portland Grizzly / Havana Summit September 2012 San Diego Folsom / Grizzly Summit April 2012 San Francisco Essex / Folsom Summit May 2014 Atlanta Icehouse / Juno Summit Experimental “bare metal” driver for Nova Became its own project, Independent Became a recognized “related” project Became a recognized “incubated” project Slated to become recognized as a “core” project.

  14. Heat Background 14

  15. Heat Described “Why ‘Heat’? It makes the clouds rise!” “The mission of the OpenStack Orchestration program is to create a human- and machine-accessible service for managing the entire lifecycle of infrastructure and applications within OpenStack clouds.” “Heat is the main project in the OpenStack Orchestration program. It implements an orchestration engine to launch multiple composite cloud applications based on templates in the form of text files that can be treated like code.” “Heat provides a template based orchestration for describing a cloud application by executing appropriate OpenStack API calls to generate running cloud applications.“

  16. Heat Explained – Overview “Orchestration” is a great industry buzz word but what does it mean? OpenStack resource abstraction and orchestration: VM Instances Networks Routers … “Typically” Virtual (See Ironic Project) • Orchestration – “The automated arrangement, coordination, and management of complex computer systems, middleware, and services.” • Programmatic Management • RESTful API • Agnostic • Consistent • Abstracted user experience • Worlflow • AAA • Error Checking / Correction Infrastructure resource abstraction and orchestration: Compute Power Switches Block Storage … “Typically” Physical

  17. Heat Explained – IaaS vs. PaaS Another way to look at where the Heat service fits and what it provides DBaaS VPNaaS MaaS DRUPALaaS Jason’s Mac Core Projects

  18. Heat Architecture 18

  19. Heat Main Components heat The heat tool is a CLI which communicates with the heat-api to execute AWS CloudFormation APIs. End developers could also use the heat REST API directly. heat-api The heat-api component provides an OpenStack-native REST API that processes API requests by sending them to the heat-engine over RPC. heat-api-cfn The heat-api-cfn component provides an AWS Query API that is compatible with AWS CloudFormation and processes API requests by sending them to the heat-engine over RPC. heat-engine The heat engine’s main responsibility is to orchestrate the launching of templates and provide events back to the API consumer.

  20. Heat Architecture (Quick Overview) • Concepts to cover • Stateless (API) • Stateful • DB • MQ • Interfaces • Web-UI • CLI • API

  21. Heat Operations 21

  22. Heat is HOT • The power of Heat is HOT (Heat Orchestration Templates) • Whatever you can do “by hand” (CLI, API, Web-UI) in OpenStack can likely be executed through a Heat Orchestration Template • Initial goal of Heat was to provide a service comparable to AWS’s “Cloud Formation” • Cloud Formation = “Service Deployment” or “Environment Deployment” • Instead of deploying a single instance, deploy all components to create a service, e.g. 2 web, 2 app, 2 db, networks, routers, etc. • Service deployment continues to be the most popular Heat use case • Autoscale also a very popular use case • Heat can leverage Ceilometer metering data and through watermarks and triggers scale

  23. Heat Demo 23

  24. Demo Environment Setup • Configuration notes on how this demo environment was setup • MacBook Pro • Retina, 15-inch, Early 2013 • OS X 10.9.2 • 256 GB SSD • 2.7 GHz Intel I7 (8 cores – single socket quad core /w HT) • 16 GB of 1600 MHz DDR3 • VMware Fusion 5.0.4 • Single Virtual Machine • Disk 1 – 20 GB, pre-allocated, broken into 2 GB files (OS and OpenStack) • Disk 2 – 6 GB, pre-allocated, broken into 2 GB files (Cinder-Volumes) • 4 vCPUs • 8 GB RAM • USB, camera, sound, Bluetooth, printer, video acceleration, debugging, etc. off • Hard set VT acceleration, nested hypervisor, etc. support on • Single bridged NIC • Default Ubuntu Server 12.04.4 LTS, x64 installation • Devstack (full details in references section)
