Techniques for communication in hybrid cloud system
Aspects of communication of a client device with a private or hybrid cloud are described. In some aspects, a private host computer is determined as being connected to a private network. The private network differs from a network to which the client device is connected. A virtual private network is established between the client device and the private host computer. The virtual private network being established using a virtual private network server that includes a connection to the private host computer through the private network. A request is transmitted to the private host computer through the virtual private network. The request includes an origin value, wherein instructions associated with the origin value are allowed to access resources of the private host computer.
1. A system comprising:
a client device comprising a processor; and
a storage device comprising executable instructions that are executed by a processor, causing the 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.
2. The system of claim 1 , wherein the web application is downloaded from the public host computer.
3. The system of claim 2 , wherein the command causes a live migration of the virtualized execution context.
4. The system of claim 1 , wherein the executable instructions are executed by the processor, further causing the client device to at least: transmit a hypertext transfer protocol options request comprising an origin header that specifies the origin value.
5. The system of claim 1 , wherein the web-based application is associated with the origin value of the public host computer.
6. The system of claim 5 , wherein the web-based application is received from the public host computer.
7. The system of claim 1 , wherein the virtualized execution context comprises at least one of a virtual machine and a container.
8. 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.
9. The method of claim 8 , wherein the web application is downloaded from the public host computer.
10. The method of claim 9 , wherein the command causes a live migration of the virtualized execution context.
11. The method of claim 8 , further comprising:
transmitting a hypertext transfer protocol options request comprising an origin header that specifies the origin value.
12. The method of claim 8 , wherein the web-based application is associated with the origin value of the public host computer.
13. The method of claim 8 , further comprising:
transmitting, to the private host computer, at least one of data or a command for managing virtualization resources of the hybrid cloud system.
14. 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.
15. The non-transitory computer readable storage medium of claim 14 , wherein the web application is downloaded from the public host computer.
16. The non-transitory computer readable storage medium of claim 15 , wherein the command causes a live migration of the virtualized execution context.
17. The non-transitory computer readable storage medium of claim 14 , wherein the executable instructions are executed by the processor, further causing the client device to at least:
transmit a hypertext transfer protocol options request comprising an origin header that specifies the origin value.
18. The non-transitory computer readable storage medium of claim 14 , wherein the web-based application is associated with the origin value of the public host computer.
19. The non-transitory computer readable storage medium of claim 14 , wherein the web-based application is received from the public host computer.
20. The non-transitory computer readable storage medium of claim 14 , wherein the virtualized execution context comprises at least one of a virtual machine and a container.
