Montreal Linux MeetUp - OpenStack Overview (2017.10.03)

  1. 1. @cloudops_ OpenStack Overview October 3rd 2017
  2. 2. Stacy Véronneau ● Director of OpenStack Solutions and Lead OpenStack Architect at CloudOps. ● Using public cloud resources since 2007 ● Started ‘exploring’ OpenStack at Folsom and using at Grizzly ● OpenStack MeetUp organizer ○ Montreal, Ottawa, Edmonton and Toronto(Co-Org) ● Speaker at OpenStack Days and Summit ○ Austin, Montreal, Barcelona, Boston, Ottawa ● OpenStack Mentor since August 2017
  3. 3. @cloudops_Page About CloudOps 3 We enable our customers to own their destiny in a cloudy world by leveraging open source cloud orchestration and best of breed technologies. Our team has built and continues to support dozens of regional clouds for telco and community cloud service providers around the world. We’ve helped hundreds of software companies migrate to and scale their businesses on regional cloud platforms such as and public clouds such as Google Cloud Platform and Amazon Web Services.
  4. 4. @cloudops_ What is OpenStack?
  5. 5. @cloudops_Page What is OpenStack? 5 As described by Wikipedia “OpenStack is a cloud computing project aimed at providing an infrastructure as a service (IaaS).” The software platform consists of interrelated components that control hardware pools of processing, storage and networking”
  6. 6. @cloudops_Page What is OpenStack? 6 ● What it is ○ Abstraction Layer ○ A group of interrelated projects ○ IaaS Solution ○ Community Driven ● What it isn’t ○ Interdependent project (Exceptions Apply) ○ A complete standalone solution, extra components are needed ○ Standalone Virtualisation solution
  7. 7. @cloudops_Page OpenStack Capabilities 7 ● Virtual machines (VMs) on demand ○ Provisioning ○ Snapshotting ● Networks ○ Provisioning ○ Isolation ● Storage for VMs and arbitrary files ● Multi-tenancy ○ Quotas for different projects, users ○ User can be associated with multiple projects
  8. 8. @cloudops_ History and a High Level Recap
  9. 9. @cloudops_Page History 9 ● Started in 2010 by and ● Foundation created in 2012 ● Latest release was on August 30th 2017 and is named Pike The Mission: “To produce the ubiquitous Open Source Cloud Computing platform that will meet the needs of public and private clouds regardless of size, by being simple to implement and massively scalable”.
