Techniques for communication in hybrid cloud system

A method performed by a client device, the method comprising:

• executing, in the client device, a web-based application that facilitates transfer of a virtualized execution context within a hybrid cloud system comprising a public host computer and a private host computer;
• determining that the private host computer is connected to a private network that differs from a network to which the client device is connected;
• establishing a virtual private network with the private host computer, the virtual private network being established through a virtual private network server comprising a connection to the private host computer through the private network;
• transmitting, by the web-based application, an options request to a private host computer and receive a response from the private host computer through a virtual private network, the response comprising an access-control-allow-origin header that specifies an origin value;
• transmitting, to the private host computer, a command for managing virtualization resources of the hybrid cloud system;
• and
• transferring, by the web-based application, the virtualized execution context through the virtual private network using the client device as a relay between the public host computer and the private host computer, the virtualized execution context being transferred along with the origin value of the public host computer, wherein instructions associated with the origin value are allowed to access resources of the private host computer.

A non-transitory computer readable storage medium embodying executable instructions that are executed by a processor, causing a client device to at least:

• execute, in the client device, a web-based application that facilitates transfer of a virtualized execution context within a hybrid cloud system comprising a public host computer and a private host computer;
• determine that the private host computer is connected to a private network that differs from a network to which the client device is connected;
• establish a virtual private network with the private host computer, the virtual private network being established through a virtual private network server comprising a connection to the private host computer through the private network;
• transmit, by the web-based application, an options request to a private host computer and receive a response from the private host computer through a virtual private network, the response comprising an access-control-allow-origin header that specifies an origin value;
• transmit, to the private host computer, a command for managing virtualization resources of the hybrid cloud system;
• and
• transfer, by the web-based application, the virtualized execution context through the virtual private network using the client device as a relay between the public host computer and the private host computer, the transfer comprising the origin value of the public host computer, wherein instructions associated with the origin value are allowed to access resources of the private host computer.
