Abstract

A method for establishing a support environment for a program may include identifying one or more support environment features depended upon by the program to run on one or more nodes, selecting one or more support software components indicated to provide the features, loading the selected support components on the one or more nodes, configuring the selected support components based on the program, and causing the program and the selected support components to be executed on one or more nodes.

Claims

1. A method comprising:

identifying, by a processing device, a support environment feature depended upon by a program to execute on a virtual machine, the execution of the program being facilitated by a Platform-as-a-Service (PaaS) environment;

the PaaS environment including an Infrastructure-as-a-Service (IaaS) with a platform running on said IaaS;

the platform being delivered as an auto-clustering virtual machine image, resulting in one or more virtual machines;

selecting a support software component indicated to provide the feature in view of the identified support environment feature, wherein the selecting is executed by applying a business logic to the support component;

the support component comprising a list of hooks in the support component;

loading the selected support component on the one or more virtual machines;

configuring the selected support component in view of the program; and

causing the program, the selected support component, and a hook to be executed on the one or more virtual machine;

receiving an indication that a status for the selected support component has changed from available to unavailable;

pausing the execution of the program;

unloading the selected support component from the one or more virtual machines;

determining an alternative support component;

loading the alternative support component on the one or more virtual machines; and

unpausing the execution of the program.

2. The method of claim 1, further comprising, for the selected support component:

identifying a support environment feature depended upon by the selected support component;

for the feature identified for the selected support component, identifying a support component indicated to provide the feature.

3. The method of claim 1 wherein the support environment feature is identified using a dependency declaration explicitly constructed for the program.

4. The method of claim 1 wherein the identifying comprises analyzing an application'"'"'s code to infer the identified support environment feature.

5. The method of claim 1 wherein the program is coded in an interpreted or compiled language, and the identified support environment feature is a runtime for the interpreted or compiled language.

6. The method of claim 1 wherein the program is a web application, and the identified support environment feature includes a static web server service and a dynamic web server service.

7. The method of claim 1 wherein the program is a web application, and the identified support environment feature includes a middleware service.

8. The method of claim 1 wherein the program is a web application, and the identified support environment feature includes a framework service.

9. A method comprising:

identifying, by a processing device, a support environment feature depended upon by a program to execute on a virtual machine, the execution of the program being facilitated by a Platform-as-a-Service (PaaS) environment;

the PaaS environment including an Infrastructure-as-a-Service (IaaS) with a platform running on said IaaS;

the platform being delivered as an auto-clustering virtual machine image, resulting in one or more virtual machines;

detecting, after a support environment has been established for the program by loading a first support component indicated to provide a business logic, and a support environment feature identified as being depended upon by the program, an event relating to an availability of a second support component indicated to provide a selected identified feature, the first support component comprising a list of hooks in the first support component;

causing the program, the first support component, and a hook to be executed on the one or more virtual machines;

receiving an indication that a status for the first support component has changed from available to unavailable;

pausing the execution of the program;

in response to the event, unloading the loaded first support component indicated to provide the selected feature;

loading the second support component indicated to provide the selected feature other than the unloaded first support component, and

unpausing the execution of the program.

10. The method of claim 9 further comprising:

prior to the unloading, pausing execution of the program; and

subsequent to the loading, resuming execution of the program.

11. The method of claim 10 wherein the detected event is an indication that a new support component indicated to provide the selected feature has become available.

12. A non-transitory computer readable storage medium including instructions that, when executed by a processing device, cause the processing device to execute operations for establishing a support environment for a program, the operations comprising:

identifying, by the processing device, a support environment feature depended upon by the program to execute on a virtual machine, the execution of the program being facilitated by a Platform-as-a-Service (PaaS) environment;

the PaaS environment including an Infrastructure-as-a-Service (IaaS) with a platform running on said IaaS;

the platform being delivered as an auto-clustering virtual machine image, resulting in one or more virtual machines;

selecting a support software component indicated to provide the feature in view of the identified support environment feature, wherein the selecting is executed by applying a business logic to the support component, the support component comprising a list of hooks in the support component;

loading the selected support component on the one or more virtual machines;

configuring the selected support component in view of the program;

causing the program, the selected support component, and a hook to be executed on the one or more virtual machines;

receiving an indication that a status for the selected support component has changed from available to unavailable;

pausing the execution of the program;

unloading the selected support component from the one or more virtual machines;

determining an alternative support component;

loading the alternative support component on the one or more virtual machines; and

unpausing the execution of the program.

13. The non-transitory computer readable storage medium of claim 12, wherein the operations further comprises:

for the selected support component, identifying a support environment feature depended upon by the selected support component;

for the feature identified for the selected support component, identifying a support component indicated to provide the feature.

14. The non-transitory computer readable storage medium of claim 12 wherein the support environment feature is identified using dependency declarations explicitly constructed for the program.

15. The non-transitory computer readable storage medium of claim 12 wherein the identifying comprises analyzing an application'"'"'s code to infer the identified support environment features.

16. The non-transitory computer readable storage medium of claim 12 wherein the program is coded in an interpreted or compiled language, and the identified support environment feature is a runtime for the interpreted or compiled language.

17. The non-transitory computer readable storage medium of claim 12 wherein the program is a web application, and the identified support environment feature includes a static web server service and a dynamic web server service.

18. The non-transitory computer readable storage medium of claim 12 wherein the program is a web application, and the identified support feature includes a middleware service.

19. The non-transitory computer readable storage medium of claim 12 wherein the program is a web application, and the identified support environment feature includes a framework service.
