The document provides an overview of OpenStack, an open source cloud computing platform. It describes OpenStack's architecture which includes key components like Nova (compute), Swift (object storage), Glance (images), Keystone (identity), Neutron (networking), and Horizon (dashboard). It discusses OpenStack's time-based release cycle and development process. It also highlights some large companies that use OpenStack like PayPal, Intel, Bloomberg and Comcast.

sacrificing the availability. By
leveraging the collective
innovation of the OpenStack
community, we can develop and
grow our private cloud much
quicker without having to
reinvent anything.”

10. Intel Uses OpenStack
User Footprint
“OpenStack has dramatically
reduced the amount of time it
takes to provision services and
automatically resolve resource
issues. We can now deploy a
VM in just five to 10 minutes,
provide faster self
services to our customers,
and offer a more reliable
infrastructure with rolling
updates that will keep our
infrastructure current without
burdening staff.

17. What is OpenStack?
OpenStack is a cloud operating system that controls large pools of
compute, storage, and networking resources throughout a datacenter, all
managed through a dashboard that gives administrators control
while empowering their users to provision resources through a web
interface.
It can be managed using CLIs and APIs.

nova-api accepts and responds to end user compute API calls.
The nova-compute process is primarily a worker daemon that creates
and terminates virtual machine instances via hypervisor's APIs
(XenAPI for XenServer/XCP libvirt for KVM or QEMU, VMwareAPI
,
for VMware, etc.).

24. Swift (Object Store)
●
The swift architecture is very distributed to prevent any
single point of failure as well as to scale horizontally. It
includes the following components:
–
–
Account servers manage accounts defined with the object storage
service.
–
Container servers manage a mapping of containers (i.e folders)
within the object store service.
–
24
Proxy server (swift-proxy-server) accepts incoming requests via
the OpenStack Object API or just raw HTTP
.
Object servers manage actual objects
nodes.
(i.e. files) on the storage

25. Glance (Images Service)
●
Glance has four main parts to it:
–
glance-api accepts Image API calls for image discovery, image
retrieval and image storage.
–
glance-registry stores, processes and retrieves
images
–
A database to store the image metadata.
A storage repository for the actual image files.

Keystone provides a single point of integration for
OpenStack policy, catalog, token and authentication.
Keystone handles API requests as well as providing
configurable catalog, policy, token and identity services.

27. Neutron (Networking)
●
●
OpenStack Networking provides "network connectivity as
service" between interface devices managed by other
OpenStack services (most likely Compute). The service
works by allowing users to create their own networks and
then attach interfaces to them.
