Abstract

In accordance with an embodiment, described herein is a system and method for automatic porting of software applications into a cloud computing environment (cloud environment, cloud). A cloud service enables software developers to deploy user applications to run within the cloud environment. When a user application is deployed to the environment, a deployment logic determines those aspects of the application, such as certain service usages, that may be incompatible with features provided by the environment, or that should use a particular cloud service, and automatically ports the application, including the use of one or more handlers or extensions, for use within the environment. For example, a user application may have been originally developed to use JAVAMAIL™, which presents a security risk in a cloud environment. To minimize such risk, the application can instead be ported to use, for example, a REST-based e-mail service supported by the cloud environment.

Claims

1. A non-transitory computer readable storage medium, including computer-readable instructions stored thereon, which when read and executed by one or more computers, cause the one or more computers to perform a method comprising:

providing, at a computing environment that enables software applications to be compiled and deployed to run within the computing environment, one or more service configurations,

wherein each service configuration of the one or more service configurations defines a service usage to be found within source code of the software applications to be compiled and deployed, together with an associated action to be performed instead of the service usage;

receiving a software application to be compiled and deployed to the computing environment, wherein the software application includes one or more service usages provided within a source code of the software application and associated with a service configuration;

for each service usage found within the source code of the software application and associated with a service configuration;

determining a matching service configuration for the service usage, and an associated action defined by the matching service configuration, to be performed instead of the service usage, and

modifying the software application during compilation, according to the matching service configuration and associated action defined by the matching service configuration, to create an application runtime,

including replacing code within the software application associated with the service usage, with a modified code for use within the computing environment; and

packaging a handler, with the software application as modified, to enable the software application as modified to run within an application runtime within the computing environment and to use a corresponding service provided by the computing environment.

2. The non-transitory computer readable storage medium of claim 1, wherein the modified code is configured to, upon deployment of the software application to the computing environment, use the corresponding service provided by the computing environment.

3. The non-transitory computer readable storage medium of claim 2, wherein the modified code is configured to invoke the handler to use the corresponding service provided by the computing environment.

4. The non-transitory computer readable storage medium of claim 3, wherein at least one service configuration defines a service usage that is a method invocation, and wherein the modified code is configured to forward the method invocation to the handler, together with a context of the method invocation, for use by the handler in processing the method invocation.

5. The non-transitory computer readable storage medium of claim 3, wherein the computer-readable instructions further includes instructions to:

provide access to one or more registered extensions that are adapted to be bound to the handler, to be used with the corresponding service provided by the computing environment.

6. The non-transitory computer readable storage medium of claim 5, wherein at least one service configuration defines a service usage that is a method invocation, and wherein a registered extension performs the method invocation with the corresponding service, on behalf of the software application.

7. The non-transitory computer readable storage medium of claim 1, wherein the computing environment is a cloud environment.

8. The non-transitory computer readable storage medium of claim 7, wherein the software application is a Java software application, and wherein the cloud environment includes a Java cloud service component that enables creation of Java service instances for use in provisioning and deployment of the Java software application.

9. The non-transitory computer readable storage medium of claim 7, the software application is deployed as an application runtime to the cloud environment, including binding one or more registered extensions to the software application to use a corresponding cloud service of the cloud environment.

10. The non-transitory computer readable storage medium of claim 1, wherein the computer-readable instructions further includes instructions to:

receive a software application which includes a service usage that triggers e-mails from within the software application, and

modify the software application during compilation, to replace one or more e-mail function calls, with calls to a corresponding e-mail service provided by the computing environment.

11. The non-transitory computer readable storage medium of claim 10, wherein the computer-readable instructions further includes instructions to:

modify the software application during compilation and deployment, to replace one or more calls to a JavaMail API, with calls to at least one of a REST or other API provided by the computing environment.

12. The non-transitory computer readable storage medium of claim 10, wherein the computer-readable instructions further includes instructions to:

associate one of a quota or limit with a user, to restrict an amount of e-mails that can be sent by that user using the corresponding e-mail service.

13. The non-transitory computer readable storage medium of claim 10, wherein the computer-readable instructions further includes instructions to:

authenticate a user prior to allowing the user to send e-mail using the corresponding e-mail service, using an identity domain manager.

14. The non-transitory computer readable storage medium of claim 1, wherein the computer-readable instructions further includes instructions to:

modify the software application to replace one or more function calls within the application to output application information, with calls to a corresponding service provided by the computing environment.

15. The non-transitory computer readable storage medium of claim 14, wherein the corresponding service provided by the computing environment is a logger that enables application-related output messages to be written to service logs.

16. The non-transitory computer readable storage medium of claim 1, wherein the computer-readable instructions further includes instructions to:

modify the software application to handle name directory lookups differently, when the software application is used in different computing environments.

17. The non-transitory computer readable storage medium of claim 16, wherein the different computing environments includes a plurality of cloud environments, and wherein each particular cloud environment binds a particular resource component against a different lookup name for use with that cloud environment.
