This document provides an overview of OpenStack, an open source cloud computing platform. It discusses the history and origins of OpenStack at NASA and Rackspace, describes some of the core components including Nova (compute), Swift (object storage), Glance (image service), Cinder (block storage), Quantum/Neutron (networking), Keystone (identity), and Dashboard (web UI). It also outlines some key features of these components such as distributed architecture, API access, security groups, floating IPs, and pluggable networking backends. Finally, it encourages contributions to the OpenStack community through coding, documentation, translation, and other assistance.

- 4. Openstack History NASA Rackspace OpenNebula Cloud Files Nova - compute Swift - Storage
- 5. What the duck is that? ● It's cloud framework, duh ! ● Written using Python ! ● Apache Licensed, Yay :) ● Backed by biggies ● ...
- 6. Components ● Nova ● Swift ● Glance ● Ceilometer ● Cinder ● Others: ● Quantum – Memcache ● Keystone – RabbitMQ
- 7. Nova ● Compute part ● KVM | XEN | LXC ● ARM / x86 / AMD64 ● Complete instance lifecycle management
- 8. Features ● Commodity Server pool ● Flat / DHCP / VLAN / IPv6 ● API access ● Distributed architecture ● Floating IPs ● Security groups and RBAC
- 9. Quantum ● Network connectivity as a service ● Pluggable / Scalable ● API driven ● Flat / Flat DHCP / VLAN DHCP ● Dynamic Floating IPs ● Extension framework – IDS / firewalls – - Lead balancers / VPNs
- 10. Quantum (contd..) ● Quantum plugin – Manages p/v-switches – Both open source and proprietary allowed
- 11. Keystone ● Identity and access management ● Passwd, token, key based access ● LDAP? Oh, yes! ● Service lists ● RBAC ● Did I mention APIs??
- 12. Glance ● Delivery service – Disk and Server images ● REST in peace.. :) ● Snapshots ● Formats ● Raw, qcow2, OVF ● AMI, VHD, VDI, VMDK
- 13. Dashboard
- 14. Storage
- 15. Cinder ● Block storage service ● Persistent ● Mountable ● Analogous to EBS
- 16. Swift
- 17. Swift ● Object Store ● Analogous to S3 ● Infinite Storage ● REST based API ● Consistent Hash ring ● HEAD , PUT, GET, POST, DELETE
- 18. Heroes are awesome ● Code ● File bugs / Fix bugs ● Translate ● Document ● Help out / Educate ● Build something awesome!
- 19. Heeeeelp!
