Azure Local switchless 3-node cluster with Arc Gateway provides a hyperconverged infrastructure pattern eliminating traditional network switches for simplified on-premises deployment. Admin operators connect through Azure Arc Gateway to manage three Azure Local nodes that communicate directly via switchless interconnect, while private endpoints secure access to Key Vault cluster secrets and Storage Account cloud witness. This architecture demonstrates Azure's hybrid-first approach, reducing operational complexity and network dependencies while maintaining full Azure control plane integration and compliance monitoring. Fork this diagram on Diagrams.so to customize subnet ranges, add additional nodes, or adapt the private endpoint configuration for your environment. The switchless topology is ideal for edge locations and remote offices where network infrastructure must be minimal yet resilient.
