OpenStack is an open-source cloud computing platform that consists of interrelated projects that provide software for building and managing public and private clouds. The projects include Nova (compute), Swift (object storage), Glance (image repository), Keystone (identity), Quantum (networking), Cinder (block storage), and Horizon (dashboard). OpenStack aims to produce a cloud computing platform that is simple to implement, massively scalable, and feature-rich. It has a large global community of developers and is used by many large companies and organizations.

Components Of Openstack

14. What is Horizon ?
 Horizon is a web-based interface to OpenStack.
 The OpenStack dashboard provides administrators and users a
graphical interface to access, provision and automate cloud-based
resources.
 The extensible design makes it easy to plug in and expose third
party products and services, such as billing, monitoring and
additional management tools

15. OpenStack Projects : Communication Types

16. What is Keystone ?
 Keystone is an authentication framework for OpenStack.
 It provides the ability to add users to groups (also known as
tenants) and to manage permissions between users and groups.
 Permissions include the ability to launch and terminate instances
or to administer everyone’s instance

17. Keystone Architecture

18. What is Nova Compute ?

19. Start VM Provisioning

20. What is Quantum ?
 Quantum is an OpenStack project to provide "network
connectivity as a service" between interface devices (e.g.,
vNICs) managed by other OpenStack services (e.g., nova).

21. Configure Network

22. Configure Network - Contd

23. Cinder

25. Request Volume

27. What is Swift?
 Swift is a very robust object storage system that can manage
petabytes of data spread across several servers..

28. What is Glance ?
 Glance provides a catalogue of images. “Images” in this case can
be thought of as a virtual machine template.
 When launching an instance in OpenStack, you choose a
template from Glance, such as Ubuntu 12.04 or Centos 5.8, and
then OpenStack creates your instance based on that template

29. Glance Image Formats

30. Request VM Image from Glance

31. What is Ceilometer ?
 Collecting per user/tenant usage data
○ For every OpenStack component
○ In a single place
 Retrieving usage data
○ From a single place
 Doing this with an open source project
○ Everyone did this in its corner so far :-(
Ultimate Goal : Billing Customers
○ or whatever else you want, like capacity planning or pretty usage
statistics…
