Cluster has EIP • No direct connection between Edge nodes • Goal • Cloud VM and Edge nodes run as in one cluster • KubeBus Virtual Router • Public Endpoint for Edge connection • Router to connect • Cloud

Nodes running at private network • Connect to Cloud behind NAT gateway • Mightn’t have direct connection between Edges • Edge Nodes connect to Cloud with Internet • Low bandwidth • High latency Related TCP • KubeBus Client/Server Proxy to proxy Http packets • Multiplex https connections over TCP connection, i.e. “L7 tunnel” • Multitenant service publishing • Global namespace URL definition • Host Name
