The gateways page

From the Gateways page, all registered logical gateways and gateways nodes can be visualized and managed. Details such as gateway names and description, load balancer URLs and number of APIs deployed are visible. Also, note that next to the gateway name the version of the gateway is visible. This is important to make sure that the version implemented is compatible with the version of the management service (ideally both should be in the same version):

Management portal–gateways page

A logical gateway as the name suggests, represents a grouping of one or many gateway nodes. A gateway node is an actual physical instance of the gateway that's running on a compute instance (could be in the cloud and/or on-premise) and is capable of handling API requests.

Logical gateways and gateway nodes

By clicking on a given gateway listed, the Gateway details page opens, and from there gateway settings, gateway properties, physical gateway nodes belonging to the logical gateway, deployments, grants, and gateway analytics can be visualized and certain properties edited.
