In-Depth Information
Neuron provides different networking models for a variety of applications, including
flat networks or VLANs for separating traffic and servers. Its IP address management facil-
ity allows for dedicated static IP addresses or DHCP, and the use of floating IP addresses
allows the rerouting of traffic to any computing resource, thereby allowing for the redirect-
ing of traffic in the case of failure or required maintenance. Users will be able to provision
their own networks, control all traffic, and have freedom in connecting their servers and
other computing resources.
Dashboard (Horizon)
Horizon is the front-end interface that gives administrators and users a graphical interface
to access in order to provision, set up, and automate cloud computing resources. The design
of the interface allows for third-party products such as billing and other management and
monitoring tools to be integrated into the interface. It is also customizable to reflect the
brand of the service provider using it.
The dashboard is just the graphical way of interacting with OpenStack resources; however,
developers are also able to do this through the native OpenStack API or the EC2 compatibility
API. FigureĀ 3.4 shows the Horizon dashboard used with Ubuntu.

Other Modules
This sums up the major modules of OpenStack. There are still other modules that add value
and ensure that OpenStack becomes a very enticing option for cloud computing providers.
They are as follows:
Identity Service (Keystone) The central directory and authentication system.
Image Service (Glance) The module for registration and delivery for server and disk
images, a part of OpenStack's backup system.
