If your microservices need to communicate with other nodes in your network, ioFog includes an optional daemon called the Connector. The Connector assists in providing automatic discovery and NAT traversal, brokering direct peer-to-peer (P2P) communication when possible.
Similar to the Controller, your Connector can run on any compatible hardware that is network accessible by all of your edge nodes running an Agent. Usually that means either having a static IP address or DNS records. A common solution is to run your Connector on a cloud provider like Amazon Web Services or Google Cloud Platform, but it's also possible to run the Connector directly on one of your edge nodes or other local hardware.
For full usage details see the Connector CLI Usage page.
