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.

5. Categories of Clouds

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
Storage
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
