Remote management of distributed datacenters
View Patent ↗A cloud-based management system for distributed datacenters provides remote management of the datacenters from terminals at various locations. A virtual cloud-based operating system facilitates a transparent system call architecture, permitting subscribers to deploy, configure and manage operations at machines operating on different local operating systems. The virtual operating system can canonicalize available resources into a namespace to expose the resources as files at terminals. Asynchronous execution of subscriber commands across a group of target machines is provided with a notification procedure to control bandwidth and resource allocation. A file distribution model without a central controller for a group of target machines is provided to alleviate interaction with the management cluster for file distribution.
1. A method comprising:
receiving, by a terminal, a system call associated with an operating system of a client device;
determining whether the system call requests to access a remote resource located on a remote device;
converting, based on a determination that the system call requests to access the remote resource, the system call to a system protocol packet;
encapsulating the system protocol packet into a communication protocol packet; and
sending the communication protocol packet to a remote management server.

3. The method of claim 1 , wherein the determining whether the system call requests to access a remote resource comprises checking a remote processing library.
4. The method of claim 1 , wherein the encapsulating the system protocol packet into the communication protocol packet comprises creating an encoded packet and embedding the encoded packet into a header of the communication protocol packet.
5. The method of claim 1 , further comprising:
sending, based on a determination that the system call does not reference a remote resource, the system call to the operating system of the client device.
6. The method of claim 1 , further comprising:
receiving a second communication protocol packet from the remote management server, wherein the second communication protocol packet comprises a response code indicating execution of the system call at a target machine;
decoding the second communication protocol packet to extract the response code;
converting the extracted response code to a second system call for the operating system of the client device; and
causing a result of the second system call executed by the operating system of the client device to be available for the terminal.
7. The method of claim 6 , further comprising:
determining the target machine based on a certificate number encoded in a header of the second communication protocol packet.

sending the result of the second system call to the remote management server; and
receiving a resource reply from the remote management server.
10. An apparatus comprising:

convert, based on a determination that the system call requests to access the remote resource, the system call to a system protocol packet;
encapsulate the system protocol packet into a communication protocol packet; and
send the communication protocol packet to a remote management server.
11. The apparatus of claim 10 , wherein the system call comprises a user request to perform a target action or access a resource at a target machine.

send, based on a determination that the system call does not reference a remote resource, the system call to the operating system of the client device.
15. The apparatus of claim 10 , wherein the instructions when executed further cause the apparatus to:
receive a second communication protocol packet from the remote management server, wherein the second communication protocol packet comprises a response code indicating execution of the system call at a target machine;
decode the second communication protocol packet to extract the response code;
convert the extracted response code to a second system call for the operating system of the client device; and
cause a result of the second system call executed by the operating system of the client device to be available for the apparatus.
16. The apparatus of claim 15 , wherein the instructions when executed further cause the apparatus to:
determine the target machine based on a certificate number encoded in a header of the second communication protocol packet.
17. The apparatus of claim 15 , wherein the instructions when executed further cause the apparatus to:
determine a transaction corresponding to the response code based on a transaction identification number encoded in a header of the second communication protocol packet.
18. The apparatus of claim 15 , wherein the second communication protocol packet further comprises a resource request from the remote management server, and wherein the instructions when executed further cause the apparatus to:
send the result of the second system call to the remote management server; and
receive a resource reply from the remote management server.
19. A method comprising:
receiving, by an agent at a target machine and from a remote management server, a communication protocol packet comprising an encapsulated system protocol packet;
decoding the encapsulated system protocol packet to extract a system call associated with an operating system of a remote client device, wherein the system call requests to access a resource located on the target machine;
converting the extracted system call to a native system call to be executed by an operating system of the target machine;
receiving a response code indicating execution of the native system call by the operating system of the target machine;
converting the response code into a second system protocol packet;
encapsulating the second system protocol packet into a second communication protocol packet; and
sending the second communication protocol packet to the remote management server.
20. The method of claim 19 , wherein the encapsulating the second system protocol packet into the second communication protocol packet comprises creating an encoded packet and embedding the encoded packet into a header of the second communication protocol packet.
