 The Glance project provides a service where users can upload and discover data
assets that are meant to be used with other services.
 This currently includes images and metadata definitions.
 Glance image services include discovering, registering and retrieving virtual machine
images.

Nova DB
➢ OpenStack Nova is a component within the OpenStack open source cloud
computing platform developed to provide on-demand access to compute
resources by provisioning and managing large networks of virtual
machines (VMs).
➢ Nova works with VMWare, Xen, KVM, Hyper-V and other virtualization
technologies.

➢ Neutron server accepts API requests and routes them to appropriate plugins
for action.
➢ It ships with plugins and agents for Cisco virtual and physical switches, Linux
bridging, Midokua.
➢ Common agents are L3,DHCP & specific plugin agent.

➢ Horizon is the canonical implementation of OpenStack’s Dashboard, which provides
a web based user interface to OpenStack services including Nova, Swift, Keystone,
etc.
➢ Horizon is based on a Django module called django-openstack.

Case Study: CERN

Case Study: CERN
➢ European Organization for Nuclear Research.
➢ It has 21 state members, other countries contribute to experiments.
➢ Main mission is Fundamental Research.
➢ To process data, CERN has two data centres – Geneva &
Budapest.

Problem Statement
To store all the humongous data of the Large Hadron Collider, CERN wanted a private cloud infrastructure setup.
