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.

By leveraging the collective innovation of the OpenStack community, we can develop and grow our private cloud much quicker without having to reinvent anything.” Processed more than $26,000 in mobile payments every minute in 2012 OpenStack runs thousands of VMs to support their self-service developer model Internal team manages deployment and operations, using OpenStack Compute, Storage & Shared Services 9 Saran Mandair, senior director of infrastructure engineering, PayPal
- 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. Intel IT supports more than 75,000 servers in 69 data centers And more than 91,000 employees who connect to Intel resources through Das Kamhout, principal more than 138,000 mobile devices. engineer and cloud lead, Intel 10

- 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. 17
- 21. Horizon (Dashboard) Horizon is a modular Django web application that provides an end user and administrator interface to OpenStack services. 21
- 23. Nova cont. ● API – ● Computing core – ● ● 23 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.). nova-schedule process nova-conductor module
- 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. – 25 metadata about
- 26. Keystone (Identity Service) ● ● 26 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. OpenStack Networking plugins actual actions such as: – plugging and unplugging ports creating networks or subnets – IP addressing – 28 and agents perform the a
