This document provides an overview of OpenStack components for cloud computing. It discusses the core components Nova (compute), Quantum (networking), Glance (images), Swift (object storage), Horizon (dashboard), Keystone (identity), and Cinder (block storage). For each component, it describes its purpose and architecture goals like high availability and fault tolerance. It also mentions deployment options for OpenStack and concludes with asking if there are any questions.

14. Nova
• Nova is the project name for
OpenStack Compute, a cloud
computing fabric controller, the main
part of an IaaS system. Individuals and
organizations can use Nova to host
and manage their own cloud
computing systems. Nova originated as
a project out of NASA Ames Research
Laboratory.

15. Nova
• Component based architecture: Quickly add new
behaviors
• Highly available: Scale to very serious workloads
• Fault-Tolerant: Isolated processes avoid
cascading failures
• Recoverable: Failures should be easy to
diagnose, debug, and rectify
• Open Standards: Be a reference implementation
for a community-driven api
• API Compatibility: Nova strives to provide API-
compatible with popular systems like Amazon
DneprPy #0 15

16. 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).
• SDN: Software-Defined Network
• etc

17. Glance
• The Glance project provides services
for discovering, registering, and
retrieving virtual machine images.
Glance has a RESTful API that allows
querying of VM image metadata as well
as retrieval of the actual image.

18. Glance
• Component based architecture: Quickly
add new behaviors
• Highly available: Scale to very serious
workloads
• Fault tolerant: Isolated processes avoid
cascading failures
• Recoverable: Failures should be easy to
diagnose, debug, and rectify
• Open standards: Be a reference

19. Glance
• raw: This is an unstructured disk image
format
• vhd: This is the VHD disk format, a
common disk format used by virtual
machine monitors from VMWare, Xen,
Microsoft, VirtualBox, and others
• vmdk: Another common disk format
supported by many common virtual
machine monitors
• vdi: A disk format supported by
DneprPy #0 19

20. Glance
• iso: An archive format for the data contents of
an optical disc (e.g. CDROM).
• qcow2: A disk format supported by the QEMU
emulator that can expand dynamically and
supports Copy on Write
• aki: This indicates what is stored in Glance is an
Amazon kernel image
• ari: This indicates what is stored in Glance is an
Amazon ramdisk image
• ami: This indicates what is stored in Glance is
an Amazon machine image

21. Swift
• Swift is a highly available, distributed,
eventually consistent object/blob
store. Organizations can use Swift to
store lots of data efficiently, safely, and
cheaply.

23. Keystone
• Keystone is an OpenStack project that
provides Identity, Token, Catalog and
Policy services for use specifically by
projects in the OpenStack family.
DneprPy #0 23

24. Keystone
• User: has account credentials, is associated with
one or more tenants
• Tenant: unit of ownership in openstack,
contains one or more users
• Role: a first-class piece of metadata associated
with many user-tenant pairs.
• Token: identifying credential associated with a
user or user and tenant
• Extras: bucket of key-value metadata associated
with a user-tenant pair.
• Rule: describes a set of requirements for
performing an action.

25. Cinder
• Cinder is an OpenStack project to
provide “block storage as a service”.

26. Cinder
• Component based architecture: Quickly add new
behaviors
• Highly available: Scale to very serious workloads
• Fault-Tolerant: Isolated processes avoid
cascading failures
• Recoverable: Failures should be easy to
diagnose, debug, and rectify
• Open Standards: Be a reference implementation
for a community-driven api
• API Compatibility: Cinder strives to provide API-
compatible with popular systems like Amazon
