OpenStack Networking
OpenStack Networking (Neutron) is a software-defined networking (SDN) service within the OpenStack cloud computing platform that provides network connectivity as a service between interface devices managed by other OpenStack services. It allows users to create and manage networks, subnets, routers, and security groups, enabling complex network topologies in a cloud environment. It supports various networking technologies, including VLANs, VXLANs, and plugins for integration with external systems.
Developers should learn OpenStack Networking when building or managing private or public cloud infrastructures using OpenStack, as it is essential for configuring virtual networks, load balancers, and security policies in cloud deployments. It is particularly useful in scenarios requiring multi-tenant network isolation, network automation, or integration with physical network hardware, such as in enterprise data centers or telecom environments.
