Summary OpenStack Networking offers the ability to leverage the different technologies found in a data center in a virtualized and programmable manner. If the built-in features are not enough, the plugin architecture of OpenStack Networking allows for additional functionality to be provided by third parties, whether it be a commercial entity or the open source community. The security requirements of the enterprise building the cloud, as well as the use cases of the cloud, will ultimately dictate the physical layout and separation of services across the infrastructure nodes.

29 ] Installing OpenStack Installing the MySQL database client The compute nodes in the environment should be configured as MySQL clients rather than as MySQL servers. On compute01, install the MySQL client as follows: # yum -y install mysql MySQL-python Installing and configuring the messaging server Advanced Message Queue Protocol (AMQP) is the messaging technology chosen for use with an OpenStack-based cloud. Components such as Nova, Cinder, and Neutron communicate internally via AMQP and to each other using API calls.

Neutron will be installed in Chapter 3, Installing Neutron. Installing and configuring compute node components Once the Nova (Compute) services have been configured on the controller node, another host must be configured as a compute node. The compute node receives requests from the controller node to host virtual machine instances. Separating the services by running dedicated compute nodes means that Nova (Compute) can be scaled horizontally by adding additional compute nodes once all available resources have been utilized.
