BlueCat Horizon vs OpenStack Neutron

BlueCat Horizon coordinates DNS, DHCP, IP address management, and network operations across hybrid and multicloud environments. Its first generally available service, Horizon DDI Orchestration, combines SaaS-hosted IPAM with centralized DNS and DHCP orchestration. Hosted IPAM provides a central inventory of networks, subnets, and IP addresses. Lightweight agents connect existing DNS and DHCP environments, while local agents and service points can keep services running locally under Horizon's SaaS governance. Network teams can standardize changes and synchronize data through a shared interface and API. Integrations include Microsoft Active Directory, BIND, Kea, cloud DNS, third-party components, and BlueCat solutions. Granular role-based access supports delegation by region, business unit, or function. The subscription is metered by Unique Active IP, which includes addresses with DNS records, DHCP leases or assignments, or recent active discovery. Pricing is on request, and BlueCat offers a trial request form without stating a duration. Advanced DNS services are marked as coming soon; observability and AI-assisted operations are described as platform vision rather than general-availability commitments.

OpenStack Neutron provides network connectivity between interface devices managed by other OpenStack services. Its API lets operators define cloud connectivity and addressing, and manage networks, subnets, and ports. Neutron supports provider, routed provider, and self-service networks, with options including VLAN, VXLAN, GRE, and Geneve. It can configure L3 forwarding, NAT, perimeter firewalls, and virtual private networks, and works mainly with OpenStack Compute to connect instances. Plug-ins and agents are available for Open vSwitch, OVN, SR-IOV, and Macvtap, although only one networking plug-in can be used at a time. Security groups provide port-level ingress and egress firewall rules, with default-deny and anti-spoofing rules. Quality-of-service options include bandwidth and packet-rate limits, DSCP marking, and minimum rates, depending on the backend. Neutron is free and open source under Apache 2.0, for Linux and self-hosted deployments. The installation guide’s example requires at least two hosts and is framed as a learning proof of concept for people with sufficient Linux experience, not a production setup.
