Introduction to Defined Networking

Nebula open-source is a terrific option for individuals or organizations that don’t mind managing keys, certificates, and host configuration… But we’ve found that most organizations want help with that.

That’s where Defined Networking (DN) comes in: Think of it as a Defined-managed, customer-run version of Nebula that’s built for teams.

Core components of DN

  • Admin web app to manage hosts, groups, firewall, overlay IPs
  • Web service to automate enrollment and updates across every host
  • Host client software—powered by Nebula—that can automatically update certificates, keys, and configuration (including the groups-based firewall)
