OpenStack Neutron review
A broad, modular networking layer for OpenStack deployments.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OpenStack Neutron provides networking as a service for OpenStack clouds. It exposes APIs for creating and managing networks, subnets, ports, addresses, routers, and related services. The component is aimed at teams operating OpenStack environments that need Layer 2 networking, IP address management, Layer 3 forwarding, NAT, firewalls, VPNs, security groups, and quality-of-service policies in one networking layer.
Its strongest advantage is ecosystem fit. Neutron integrates with OpenStack Keystone and Nova, while its Modular Layer 2 driver framework connects mechanism drivers and agents such as Open vSwitch, OVN, SR-IOV, and Linux-based networking components. The published capabilities also include DHCP and metadata agents, floating IPs, policy segmentation, a northbound API, and support for VLAN, VXLAN, GRE, and Geneve. This makes it suitable for OpenStack architectures that need pluggable networking technologies rather than a fixed implementation.
The trade-off is focus: Neutron is an OpenStack networking component, not a standalone hosted SaaS product. Its open-source model supports self-hosted use across Linux and API-based environments, but it is not positioned as a general network-control product for organizations outside the OpenStack ecosystem. Choose Neutron when OpenStack integration, modular drivers, and a wide set of cloud networking services are central requirements. Consider an alternative when the priority is a hosted service or network management without an OpenStack control plane.
OpenStack Neutron pros and cons
- Where it wins
- Covers routing, NAT, VPN, QoS, IPAM, and security groups
- Integrates with Open vSwitch, OVN, Nova, and Keystone
- Supports VLAN, VXLAN, GRE, and Geneve networking
- Where it doesn't
- Designed for OpenStack rather than general network control
- Requires self-hosted deployment on Linux or through APIs
- Its broad modular scope can exceed a narrow networking need
