packaging the application for deployment on a cloud platform, wherein packaging the application includes creating deployable components on the cloud platform;

executing the packaged application in a sandboxed environment, wherein the sandboxed environment comprises at least one physical server, and capturing one or more application performance characteristics thereby;

executing the packaged application in a sandboxed virtualized platform and further capturing one or more application performance characteristics thereby;

mapping the one or more captured application performance characteristics to one or more service level objectives, wherein a service level objective is selected from a group of application parameters related to the cloud platform consisting of infrastructure availability, security and performance parameters; and

deriving a service level agreement on the basis of the one or more service level objectives, wherein the service level agreement comprises at least one of the one or more service level objectives.

2. The method as claimed in claim 1, further comprising performing an infrastructure feasibility study, a financial feasibility study and a technical feasibility study prior to packaging the application for deployment.

3. The method as claimed in claim 2, wherein the technical feasibility study comprises determining the ability of the application to be hosted to scale out and the compatibility of the application with the cloud platform on which the application is to be hosted.

4. The method as claimed in claim 2, wherein the infrastructure feasibility study comprises determining the availability of infrastructural resources in the cloud platform to support the deployment of the application.

5. The method as claimed in claim 2, wherein the infrastructure feasibility study comprises determining a pattern of usage of infrastructural resources by the application to be deployed in the cloud platform in order to ensure that the application to be deployed is able to coexist with at least one deployed application in the cloud platform.

6. The method as claimed in claim 2, wherein the financial feasibility study comprises determining an approximate cost involved in the deployment of the application on the cloud platform.

7. The method as claimed in claim 2, wherein the financial feasibility study comprises associating the application to be deployed with a service level selected from a set of tiered customer service levels.

8. The method as claimed in claim 1, further comprising creating at least one policy governing the management of the application in response to the service level agreement, wherein the at least one policy defines access to, and usage of, infrastructural resources by the application on the cloud platform.

9. The method as claimed in claim 8, further comprising validating a policy created against one or more requirements associated with the service level agreement by testing the deployed application.

10. The method as claimed in claim 8, wherein the at least one policy created includes a business policy, an operational policy and a provisioning policy.

11. The method as claimed in claim 8, wherein access to infrastructural resources of the cloud platform and resource allocation in case of a resource contention by processes associated with the deployed application is determined by the business policy.

12. The method as claimed in claim 8, wherein the operational policy determines an action to be taken when a predefined condition is reached.

13. The method as claimed in claim 8, wherein the provisioning policy defines a sequence of actions that are triggered by an external input and a user request.

14. The method as claimed in claim 1, wherein the testing process is iteratively repeated until all infrastructure conditions associated with the cloud platform that are necessary to satisfy the identified service level agreement are identified.

15. The method as claimed in claim 1, wherein two or more service level agreements are derived from the one or more service level objectives and each of the two or more service level agreements comprise at least one service level objective.

16. A system for deriving a service level agreement for an application, the system comprising:

at least one processor and a processor readable memory in operable communication with the at least one processor, with at least one interface operable to provide a communication link to at least one network device, the at least one processor thereby configured to;

package the application for deployment on a cloud platform, wherein packaging the application includes the creation of deployable components on the cloud platform;

execute the packaged application in a first sandboxed environment comprising at least one physical server and a second sandboxed environment comprising at least one virtualized computing environment, and capture one or more application performance characteristics exhibited in each of the sandboxed environments;

map the one or more captured application performance characteristics to one or more service level objectives, wherein a service level objective is selected from a group consisting of business and infrastructural parameters related to the cloud platform; and

derive a service level agreement on the basis of the one or more service level objectives, wherein the service level agreement comprises at least one of the one or more service level objectives.
