PayPal Uses OpenStack User Footprint

“We needed agility without 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.”

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. Intel IT supports more than 75,000 servers in 69 data centers And more than 91,000 employees who connect to Intel resources through more than 138,000 mobile devices. 10

Getting technical about

OpenStack

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

interface. a web

It can be managed using CLIs and APIs.

The swift architecture is single point of failure as

very distributed to prevent any well as to scale horizontally. It

Neutron (Networking)

OpenStack Networking provides "network connectivity as a ●

service" between interface OpenStack services (most works by allowing users to
