Neutron Physical Deployment Scenario-5 minutes a day to play OpenStack (68)

before we discussed the architecture of Neutron, This section discusses the physical deployment scenarios for Neutron:
Different nodes deploy different Neutron service components.

Scenario 1: Control node + COMPUTE node

In this deployment scenario, OpenStack consists of a control node and a compute node.

Control node
The services deployed include: Neutron server, agent for core plugin, and agent for service plugin.

COMPUTE nodes
Deploy core plugin agent, responsible for providing two layers of network functionality.

There are two points to note: 1. Core plugin and service plugin have been integrated into neutron server without the need to run separate plugin services. 2. Both the control node and the compute node need to deploy the core plugin agent, because the agent controls the node and compute nodes to establish a two-tier connection. 3. You can deploy multiple control nodes and compute nodes.

Scenario 2: Control node + network node + COMPUTE node

In this deployment scenario, OpenStack consists of a control node, a network node, and a compute node.

Control node
Deploy the neutron Server service.

Network node
The services deployed include: Core plugin agent and service plugin agent.

COMPUTE nodes
Deploy core plugin agent, responsible for providing two layers of network functionality.

The point of this scheme is to separate all the agents from the control nodes and deploy them to separate network nodes.

1. The control node is only responsible for responding to API requests through Neutron server.

2. Advanced network services such as data exchange, routing, and load balance are implemented by independent network nodes.

3. You can assume a larger load by increasing the network nodes.

4. You can deploy multiple control nodes, network nodes, and compute nodes.

This solution is especially suitable for larger OpenStack environments.

These are the Neutron two typical deployment scenarios, and the next section we start to discuss the various service components of Neutron.
You will first learn Neutron Server.
