  12 The arvados-ws server provides event notifications to websocket clients. It can be installed anywhere with access to Postgres database and the Arvados API server, typically behind a web proxy that provides SSL support. See the "godoc page":http://godoc.org/github.com/arvados/arvados/services/ws for additional information.
