Abstract

A middleware layer running on a computing device determines capabilities of the computing device in response to receiving a request for an application. The middleware layer identifies a service level agreement associated with the application. The middleware layer selects one or more services of the middleware layer to assign to the application based on the service level agreement and the capabilities of the computing device. The middleware layer determines whether to install the one or more services on the computing device or on a remote computing device based on the service level agreement, the capabilities of the computing device and properties of the one or more services.

Claims

1. A method comprising:

determining, by a middleware layer running on a computing device, capabilities of the computing device in response to receiving a request for an application;

determining, by the middleware layer, a service level agreement associated with the application;

selecting one or more services of the middleware layer to assign to the application based on the service level agreement and the capabilities of the computing device; and

determining whether to install the one or more services on the computing device or on a remote computing device based on the service level agreement, the capabilities of the computing device and properties of the one or more services.

2. The method of claim 1, further comprising:

migrating the application to an additional computing device on which the middleware layer also runs;

determining additional capabilities of the additional computing device; and

determining whether to migrate the one or more services from at least one of the computing device or the remote computing device to the additional computing device based on the service level agreement, the additional capabilities of the additional computing device and the properties of the one or more services.

3. The method of claim 2, further comprising:

determining that the additional capabilities of the additional computing device are insufficient to support a first service of the one or more services;

identifying a second service that performs a functionality performed by the first service; and

installing the second service on the additional computing device.

4. The method of claim 2, further comprising:

determining that the additional capabilities of the additional computing device exceed the capabilities of the computing device; and

migrating a first service of the one or more services from the remote computing device to the additional computing device.

5. The method of claim 1, wherein the computing device is one of a mobile phone, a tablet computer, a notebook computer, a desktop computer, or an embedded system.

6. The method of claim 1, further comprising:

determining that the capabilities of the computing device are insufficient to satisfy requirements of a first selected service;

installing a proxy for the first service on the computing device; and

installing the first service on the remote computing device, wherein the application interfaces with the proxy.

7. The method of claim 6, wherein the first service is a reliable messaging service, and wherein the proxy comprises a message queue.

8. The method of claim 1, further comprising:

determining that the capabilities of the computing device are insufficient to satisfy requirements of a first selected service;

separating the first selected service into a first component and a second component;

installing the first component of the first selected service on the computing device; and

installing the second component of the first selected service on the remote computing device.

9. The method of claim 1, wherein the properties of the one or more services comprise additional service level agreements of the one or more services.

10. A computer readable storage medium having instructions that, when executed by a computing device, cause the computing device to perform a method comprising:

determining, by a middleware layer running on the computing device, capabilities of the computing device in response to receiving a request for an application;

determining, by the middleware layer, a service level agreement associated with the application;

selecting one or more services of the middleware layer to assign to the application based on the service level agreement and the capabilities of the computing device; and

determining whether to install the one or more services on the computing device or on a remote computing device based on the service level agreement, the capabilities of the computing device and properties of the one or more services.

11. The computer readable storage medium of claim 10, the method further comprising:

migrating the application to an additional computing device on which the middleware layer also runs;

determining additional capabilities of the additional computing device; and

determining whether to migrate the one or more services from at least one of the computing device or the remote computing device to the additional computing device based on the service level agreement, the additional capabilities of the additional computing device and the properties of the one or more services.

12. The computer readable storage medium of claim 11, the method further comprising

determining that the additional capabilities of the additional computing device are insufficient to support a first service of the one or more services;

identifying a second service that performs a functionality performed by the first service; and

installing the second service on the additional computing device.

13. The computer readable storage medium of claim 11, the method further comprising

determining that the additional capabilities of the additional computing device exceed the capabilities of the computing device;

and

migrating a first service of the one or more services from the remote computing device to the additional computing device.

14. The computer readable storage medium of claim 10, wherein the computing device is one of a mobile phone, a tablet computer, a notebook computer, a desktop computer, or an embedded system.

15. The computer readable storage medium of claim 10, the method further comprising:

determining that the capabilities of the computing device are insufficient to satisfy requirements of a first selected service;

installing a proxy for the first service on the computing device; and

installing the first service on the remote computing device, wherein the application interfaces with the proxy.

16. The computer readable storage medium of claim 15, wherein the first service is a reliable messaging service, and wherein the proxy comprises a message queue.

17. The computer readable storage medium of claim 10, the method further comprising:

determining that the capabilities of the computing device are insufficient to satisfy requirements of a first selected service;

separating the first selected service into a first component and a second component;

installing the first component of the first selected service on the computing device; and

installing the second component of the first selected service on the remote computing device.

18. The computer readable storage medium of claim 10, wherein the properties of the one or more services comprise additional service level agreements of the one or more services.

19. A computing device, comprising:

a memory to store instructions for a middleware layer module;

a network interface to communicate with a remote computing device; and

a processing device, coupled to the memory and to the network interface, to execute the instructions, wherein the processing device is configured to;

determine capabilities of the computing device in response to receiving a request for an application;

determine a service level agreement associated with the application;

select one or more services of the middleware layer to assign to the application based on the service level agreement and the capabilities of the computing device; and

determine whether to install the one or more services on the computing device or on the remote computing device based on the service level agreement, the capabilities of the computing device and properties of the one or more services.

20. The computing device of claim 19, wherein the processing device is further configured to:

migrate, via the network interface, the application to an additional computing device on which the middleware layer also runs;

determine additional capabilities of the additional computing device; and

determine whether to migrate the one or more services from at least one of the computing device or the remote computing device to the additional computing device based on the service level agreement, the additional capabilities of the additional computing device and the properties of the one or more services.
