Repository of Virtual Disk Images

Provide virtual servers on demand

Provides Web Based Interface

provides authentication and authorization for all the Open Stack services.

provides "network connectivi ty as a service" between interface devices

cinder provides persistent block storage to guest VMs.

What is Horizon ?  Horizon is a web-based interface to OpenStack.  The OpenStack dashboard provides s and s 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

OpenStack Projects : Communication Types

What is Keystone ?  Keystone is OpenStack.

an

authentication

framework

for

 It provides the ability to add s to groups (also known as tenants) and to manage permissions between s and groups.  Permissions include the ability to launch and terminate instances or to ister everyone’s instance

Keystone Architecture

What is Nova Compute ?

Start VM Provisioning

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).

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

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

Glance Image Formats

What is Ceilometer ?  Collecting per /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…
