2 83840-546-03 B2 Example ArchitectureThis chapter describes the OpenStack 4 node architecture.OpenStack NodesThis guide is intended for use with OpenStack 4 node architecture, which consistsof the following nodes: Controller Compute1 Compute2 NetworkThese nodes are described in the following sections.Controller NodeIn the example architecture used in this guide, the Controller node runs theIdentity service (Keystone), Image Service (Glance), management portions of theCompute service (Nova Management) and Networking service (NeutronServer/modular layer 2 (ML2) plug-in), networking plug-in, and the dashboard(Horizon). The architecture also includes supporting services such as a database(mysql), message broker (Rabbitmq), and network time protocol (NTP).Compute NodeThere are two compute nodes (Compute1 and Compute2) to check VXLANconfiguration. In this architecture, the compute nodes use a kernel-based virtualmachine (KVM) as the hypervisor (KVM is the default hypervisor). The computenodes run the Networking node plug-in (ML2) and layer 2 agent (OVS).Network NodeThe Network node runs the networking plug-in (ML2), layer 2 agent OVS, layer 3agent, and DHCP agent. This node also handles external (Internet) connectivityfor tenant virtual machines (VMs) or instances of Compute nodes.
