client data;

the computer routine in the form of executable computer code or a reference to the computer routine; and

at least one client secret;

executing the computer routine in the container;

upon successful execution of the computer routine, returning results to the server;

upon unsuccessful execution of the computer routine, returning an error verdict to the server;

6. The computer system of claim 1 , wherein the isolated environment is a sandbox in the computer system.

7. The computer system of claim 1 , wherein the destroying the container is in response to receiving a confirmation from the server that the results or the error verdict have been received by the container.

8. The computer system of claim 1 , wherein the computer routine is independent of an operating system of the computer system.

9. The computer system of claim 1 , wherein a time to execute the computer routine is limited to a period of time corresponding to an HTTP request/response cycle.

10. The computer system of claim 9 , wherein the server is an HTTP server and the request is an HTTP request.

11. The computer system of claim 1 , wherein the returned results are in JavaScript Object Notation (JSON).

12. The computer system of claim 1 , wherein the computer system provides data isolation for each tenant such that a computer routine of one tenant is prevented from accessing a computer routine or a data of another tenant.

13. A computer-implemented method for providing an environment to execute code of a computer routine of an arbitrary application, the computer-implemented method performed by a computer system and comprising:

receiving a request from a server to execute the computer routine in a container, wherein the request includes:

client data;

the computer routine in the form of executable computer code or a reference to the computer routine; and

at least one client secret;

executing the computer routine in the container;

upon successful execution of the computer routine, returning results to the server;

upon unsuccessful execution of the computer routine, returning an error verdict to the server;

monitoring resources consumed during the execution of the computer routine, wherein the resources consumed include CPU load and memory used during the execution of the computer routine; and

destroying the container, thereby preventing persistent storage of the computer routine on the computer system,

wherein the container includes dependencies of the computer routine to run in an isolated environment in the computer system, and

wherein the isolated environment isolates the container from other containers.

14. The computer-implemented method of claim 13 , wherein the request includes a webtask token.

15. The computer-implemented method of claim 14 , wherein the webtask token is cryptographically protected from tampering and disclosure.

16. The computer-implemented method of claim 13 , the method further comprising retrieving the computer routine from a link included in the request.

17. The computer-implemented method of claim 13 , wherein the container includes all dependencies of the computer routine to run in the isolated environment in the computer system.

18. The computer-implemented method of claim 13 , wherein the isolated environment is a sandbox in the computer system.

19. The computer-implemented method of claim 13 , wherein the destroying the container is in response to receiving a confirmation from the server that the results or the error verdict have been received by the container.

20. The computer-implemented method of claim 13 , wherein the computer routine is independent of an operating system of the computer system.

21. The computer-implemented method of claim 13 , wherein a time to execute the computer routine is limited to a period of time corresponding to an HTTP request/response cycle.

22. The computer-implemented method of claim 21 , wherein the server is an HTTP server and the request is an HTTP request.

23. The computer-implemented method of claim 13 , wherein the returned results are in JavaScript Object Notation (JSON).

24. The computer-implemented method of claim 13 , wherein the computer system provides data isolation for each tenant such that a computer routine of one tenant is prevented from accessing a computer routine or a data of another tenant.

25. A non-transitory computer-readable storage medium storing instructions that, when executed by a computer processor of a computer system, perform actions comprising:

receiving a request from a server to execute a computer routine in a container, wherein the request includes:

client data;

the computer routine in the form of executable computer code or a reference to the computer routine; and

at least one client secret;

executing the computer routine in the container;

upon successful execution of the computer routine, returning results to the server;

upon unsuccessful execution of the computer routine, returning an error verdict to the server;

monitoring resources consumed during the execution of the computer routine, wherein the resources consumed include CPU load and memory used during the execution of the computer routine; and

destroying the container thereby preventing persistent storage of the computer routine on the computer system,

wherein the container includes dependencies of the computer routine to run in an isolated environment in the computer system, and

wherein the isolated environment isolates the container from other containers.

26. The non-transitory computer-readable storage medium of claim 25 , wherein the request includes a webtask token.

27. The non-transitory computer-readable storage medium of claim 26 , wherein the webtask token is cryptographically protected from tampering and disclosure.
