Physical architecture

?

13 May, 2013 OpenStack - Hedi MAGROUN 12

Physical architecture

Compute nodes● Provides virtual servers upon demand.

→ Compute : “Nova”

13 May, 2013 OpenStack - Hedi MAGROUN 13

Physical architecture

Storage node● Provides object storage.

It allows to store or retrieve files

→ Object storage : “Swift”● Provides persistent block

storage to guest Vms.

→ Block storage : “Cinder”

Physical architecture

Controller node

● Provides a modular WebUIfor all the OpenStack services. → Dashboard : "Horizon"

● Provides authentication and authorization for all the OpenStack services.→ Identity : "Keystone"

● Provides a catalog and repository for virtual disk images.● → Image : "Glance"● ...

Conceptual Architecture

Compute ("Nova"): stores and retrieves virtual disks ("images") and associated metadata in Image ("Glance")

13 May, 2013 OpenStack - Hedi MAGROUN 22

Conceptual Architecture

Image ("Glance") : can store the actual virtual disk files in the Object Storage("Swift")

13 May, 2013 OpenStack - Hedi MAGROUN 23

Conceptual Architecture

Block Storage ("Cinder") : provides storage volumes for Compute.

13 May, 2013 OpenStack - Hedi MAGROUN 24

Conceptual Architecture

Network ("Quantum"): provides virtual networking for Compute.

13 May, 2013 OpenStack - Hedi MAGROUN 25

Conceptual Architecture

All the services authenticate with Identity ("Keystone")

13 May, 2013 OpenStack - Hedi MAGROUN 26

Conceptual ArchitectureDashboard ("Horizon") :provides a web front end to the other OpenStack services
