OpenStack Neutron is a network component of OpenStack. While it is considered one of the more complex projects in the installed OpenStack Compute program, it is also very effective. This power plant is capable of creating virtual networks, routers, firewalls and more. Through Neutron, OpenStack is also able to provide “network connectivity as a service”. With the deployment of the Neutron API, other OpenStack services control UI devices.

Neutron is an OpenStack-based, flexible and secure software-specific network. Today, we’re going to break up Neutron in and out, like how it will allow you to build single tenant networks and still give you complete control over your network architecture. Continue reading to see why Neutron is the powerhouse of an OpenStack-based cloud solution.

OpenStack Neutron: The building block of the OpenStack cloud

As we mentioned earlier, Neutron is a network component of OpenStack. It is a standalone service that interacts with other projects, such as Keystone, Horizon, Novaand a glance. As with parallel projects, the deployment of Neutron requires the deployment of multiple processes for each host. Neutron, like other services, relies on Keystone authentication and authorization of all API requests. Horizon enables basic integration with the Neutron API to allow tenants to create networks. On the other hand, Nova interacts with Neutron through API calls. Nova communicates with the Neutron API so that each virtual NIC can be connected to an instance using Open vSwitch.

With OpenStack Neutron, you can take advantage of complete peace of mind thanks to network segmentation. By dividing computer networks into subnets, Neutron is able to improve performance and improve security. Thanks to the segmentation of system-shared network connections, each virtual machine has its own hypervisor in its own personal network.

One of the basic requirements of OpenStack Neutron is to provide connectivity to and from instances. This is possible thanks to two categories: provider networks and rental networks. Your OpenStack administrator creates service provider networks. These networks map directly to an existing physical network at the data center of your choice. It is possible to deploy shared service provider networks among tenants as part of the network creation process. Tenant networks, on the other hand, are user-created user groups or tenants. These networks cannot be shared with other tenants. Moreover, without a Neutron router, these networks isolate each other and everything else.
