OpenStack Architecture: Past and Future

  1. 1. OpenStack Architecture Past and Future Ken Pepple Chief Technology Officer http://www.solinea.com HAPPY 3RD BIRTHDAY AUTOMATEALLTHETHINGS
  2. 2. About Me   CTO, Solinea   Former Director of Cloud Development, Internap Public Cloud   Author of O’Reilly “Deploying OpenStack”   OpenStack Code contributor since Bexar release   Twitter @ken_pepple   IRC kpepple 2
  3. 3. Early Development (Austin – Diablo)   OpenStack started with Nova and Swift   No interaction between two services until Glance in Bexar release   Developed completely on Launchpad   My humble first commit 3 commit 16eeac71055ffa9fe0fc7a13032da4e6397121b1 Author: Ken Pepple <ken.pepple@gmail.com> Date: Sat Jan 8 17:40:06 2011 -0800 fixed doc make process for new nova version (rev530) mechanism

  12. 12. Havana Development   Ceilometer is a metering project. The project offers metering. Metering lets you know what actions have taken place, rating enables pricing and line items, and billing gathers the line items to create a bill to send to the consumer and collect payment.   Heat provides a REST API to orchestrate multiple cloud applications implementing standards such as AWS CloudFormation. 12
