The document summarizes OpenStack, an open-source cloud computing platform. It describes the core components of OpenStack including compute (Nova), object storage (Swift), image service (Glance), block storage (Cinder), identity (Keystone), networking (Quantum), dashboard (Horizon), and metering (Ceilometer). It also provides an overview of how to use and learn more about OpenStack through documentation, wikis, mailing lists, and hands-on testing environments.

3. Cloud Computing : Basics

4. What is Cloud Computing ?
« Cloud Computing is a model for enabling
convenient, on-demand network access to a shared
pool of configurable computing ressources ».
On Demand
Resources are dynamically
created depending of the demand
Multi-tenant
Resources are shared between
« clients » or « users »
Quick Elasticity
The infrastructure is flexible and
can grow or reduce easily.
Measured Service
In a Cloud, all is measurable and
clients pay what they use.

6. What is OpenStack ?

7. OpenStack
 Project created in 2010 by NASA & RackSpace
 Licence Apache 2.0 (Open-Source)
 Manage Infrastructure as a Service
 Open-Source Framework
 API, Plugins, Drivers
 Multi-tenancy, Scalable, multi-plateform
 Developed in Python
 Cycle = Ubuntu (6 months) → Folsom now.

8. * Infrastructure as a Service
OpenStack in the IaaS*
Compute

Networking
IaaS Components OpenStack Projects
Nova
(Virtual Machines)
Swift
(Object Storage)
Cinder
(Block Storage)
Quantum
(Virtual Networking)

9. 
MySQL (Backend Databases)
→ Used by Keystone, Glance, Nova,
Cinder, and Quantum.

RabbitMQ (Middleware for queuing)
→ Used by Glance, Nova, Cinder
Ceilometer and Quantum.
Common Services

10. 
Identity (Users, tenants, roles, metadata)
→ Can be backed by LDAP

Token : Authentify requests from user /
tenant

Service Catalog : Endpoint registry

Policy Services : Rule-based authorization
engine
Keystone : Identity as a Service

11. 
Discovering, Registring, Retrieving Virtual
Machine images.

The images can be stored in : regular FS,
RBD (Ceph), Amazon S3 or Swift.

Disk Formats : raw, vhd, vmdk, vdi, iso,
qcow2, aki, ari, ami.

Container Formats : bare, ovf, aki, ami, ari.
Glance : Image Delivery

12. 
Create / Delete / Attach / Detach volumes
to a VM

Storage backed by : NFS, iSCSI, SolidFire,
NetAPP, etc...
Cinder : Block Storage

13. 
Provides connectivity to Vms

Manage L2 & L3 with an API

Networking backed by plugins :
Open-vSwitch, Linux Bridge, Cisco,
OpenFlow (BigSwitch, Floodlight, NEC, Ryu,
etc), Midonet (Midokura) and NVP (Nicira /
Vmware).
Quantum : Networking

14. 
Manages Virtual Machines

Libvirt friendly

Hypervisors supported : KVM / qemu, Xen,
Hyper-V (all ready for production)

Interact with other services (Cinder,
Quantum, Glance, Keystone, etc)
Nova : Compute Service

15. 
Developped with Python / Django

Manage VMs, Images, Identity, Volumes,
Networking from a single dashboard.
Horizon : Dashboard

16. 
Provide efficient collection of metering
data, in terms of CPU and network costs

Data may be collected by monitoring
notifications

Visible to some users through a REST API

Messages are signed and non-repudiable.
Ceilometer : Metering

17. 
Build servers from templates

CloudFormation equivalent

Several modes : HA, auto-scaling

Works with Ceilometer for Alarming
Heat: Orchestration

18. 
Swift is a highly available, distributed,
eventually consistent object/blob store.

Organizations can use Swift to store lots of
data efficiently, safely, and cheaply.
Swift : Object Storage

19. How to learn and play with
OpenStack ?

20. 
RTFM : docs.openstack.org

OpenStack Wiki : wiki.openstack.org

Using Launchpad

Discuss on IRC #openstack (freenode)

Subscribe to mailing lists

Setup a testing environment (DevStack or
Basic-Install doc) and debug in real-time.
How can you learn OpenStack ?

21. 
Configure identity with Keystone

Import images with Glance

Configure networking with Quantum

Create volumes with Cinder

Create your first VM with Nova

Play with object storage
