OpenStack is an open-source cloud computing project that provides an infrastructure as a service (IaaS). It controls large pools of computing resources through a dashboard or API. OpenStack was founded in 2010 by Rackspace and NASA and is now managed by the OpenStack Foundation. It consists of several integrated projects that provide services for identity management, compute, networking, storage, and more.

Do you think that Nova, Cinder, Heat, Ceilometer, and Neutron are all references to global warming and looming apocalypse? For all those who come to the OpenStack community and wonder what all the fuss is about, this quick introduction will answer your many questions. It includes a short history of the largest Open Source project in history and will touch on the basic OpenStack components, so you will be prepared the next time someone mentions Keystone, Nova and Swift in the same sentence. This session was presented by Beth Cohen at the OpenStack meetup on Feb 19th, 2014 in Boston. Beth works for Verizon developing cool Cloud based products that she can't talk about without a strict NDA. She is a technical leader with over 25 years of experience architecting leading-edge system infrastructures and managing complex projects in the telecom, manufacturing, financial services, government, and technology industries. She has been involved in building some of the world's largest OpenStack architectures and has way too much fun at OpenStack Summits!

Open source software has progressed from being developed primarily by individuals and small teams to large projects overseen by foundations or commercial entities. There are debates around fully open source projects versus open core models, where core functionality is open but additional features are proprietary. Key considerations for organizations evaluating options include licensing terms, governance structures, impact on branding, available business models, and the overall ecosystem of users and contributors. While open core can provide traditional software vendor advantages, fully open source alternatives aim to avoid vendor lock-in and keep intellectual property communal.

The Battle of the distros - OS Summit Atlanta2014

  • 1. The Battle of the Distros Edgar Magana Principal Engineer May, 14 2014 – Atlanta OpenStack Summit Which one is better for my Cloud
  • 2. 2
  • 3. 3  Community member since 2011  Neutron core developer since 2012  Working with OpenStack distributions since … well since were created!  I DO NOT represent any specific vendor/company  My current employer (Cisco) doesn’t offer a distribution  My goal - OpenStack in Production everywhere! (neutron included)  My passion is simple - OpenStack! Introduction – Who am I?
  • 4. 4 Big Thanks to Great Developers in OpenStack Community & OpenStack Foundation Information presented here are sources from my own experience as OpenStack developer/user and from OpenStack Foundation & Community Views and technical points expressed here are solely presenter’s and does not reflect his employer’s view/positions or OpenStack foundation in anyway Information has been collected from all web resources available If something is missing or wrong here, so sorry but I could not find information about it! – personal feedback! Acknowledgments
  • 6. 6 Bummer but I will not tell you which distro you should get! Get a better idea of “few” available OpenStack distributions and products. Understand the factors to be aware when selecting a specific vendor or solution. Provide you with a set of weapons to use when a sales person calls you or during your walking over the expo floor. Evaluate whether it is possible or not to independently support an OpenStack deployment, without any company behind your data center – all open source. and …
  • 9. 9  Distribution: It is basically the open source “trunk” code that is packaged without a “lot” of proprietary components on top of it ready for production. • Mirantis • RDO • Suse • Rackspace • …  Product: It is a personalized version of the “released” code with “proprietary” features and unique deployment model considered as a final product. • Nebula • CloudScaling • PistonCloud • … OpenStack Distros vs Products – Are they the same?
  • 10. 10 What are the right questions?
  • 11. 11  Hardware – OS – Hypervisor  Reference Architecture (High Availability)  Code Upgrades & Scalability  Licensing - Cost Model  Plugins and Drivers  Customer Support - Documentation  Easy to use – Time to deploy Factors to consider when choosing a vendor
  • 12. 12 Hardware – OS – Hypervisor
  • 13. 13 • Generic/flexible on the supported hardware or very specific • Provides the tools to interconnect vendor specific drivers • Open to multiple vendor combinations • Nested Virtualization (Services as VMs) • Support very specific hardware (most of the cases) • Certificated by the OS (Enterprise Model) • Watch up for vendor’s lock-in!! Hardware – OS – Hypervisor
  • 15. 15  You need to understand the HA model and should be compatible with your current IT best practices.  HA in OpenStack is hard, make sure that all OpenStack components (nova, neutron, cider, etc.) are covered.  All those components should follow very similar HA model. Minimize the madness in your Cloud!  Understand the risk of HA. Troubleshooting your Cloud will be a beautiful nightmare.  Participate on the HA design. Reference Architecture (High Availability)
  • 16. 16 Code Upgrades & Scalability
  • 17. 17  Simple! – Be able to upgrade and scale my OpenStack Cloud!  OpenStack releases a new version every 6 months  Community work is amazing, do not loose that advantage!  Ecosystem is growing and best practices and tools for operation will be available!  Adding new zones should be possible  Adding new compute nodes should be ridiculous simple Code Upgrades & Scalability
  • 19. 19  You pay per server, socket or per subscription-based  Besides paying for Distro/Product  OS license (i.e. RHEL, SUSE Enterprise)  Support (should be included but watch out)  Upgrades (same than before)  Installation/Deployment  Testing - PoCs Licensing – Cost Model
  • 21. 21  How flexible is the solution if I want to use plugin X for Neutron and plugin Y for Nova  Let me select any storage back-end  Messaging, DB back-end systems  How easy is to change those selections – yeah I changed my mind!  Mirantis DriveLog: http://staging.stackalytics.com/driverlog/  OpenStack marketplace: http://www.openstack.org/marketplace/drivers/ Plugin and Drivers
  • 23. 23  You will have issues – Who will fix them?  The closer your deployment is to “main trunk” the more chances to get your issues solved  Is support really 24x7x365?  Action and Reaction Plans  Installation/Deployment  Docs about vendor’s sauce  Knowledge on the code! http://www.stackalytics.com/ Customer Support & Documentation
  • 24. 24 Easy to use – Time to deploy
  • 25. 25  Understand the add-ons and customization  Able to deploy a new cloud by yourself  Time constrains during deployment  The more vendors, the longer will take your deployment  Create your own testing plans  Functionality  Performance  Load  Scaling  Upgrades Time to deploy & Testing
  • 26. 26 May OpenStack be with you! If not! Outsourcing will be with you!
