13. 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
14. OpenStack Projects : Communication Types
15. 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
16. Keystone Architecture
17. What is Nova Compute ?
18. Start VM Provisioning
19. 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).
20. Configure Network

26. What is Swift? Swift is a very robust object storage system that can manage petabytes of data spread across several servers..
27. 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
28. Glance Image Formats
29. Request VM Image from Glance
30. 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…
