Abstract

In accordance with an embodiment, described herein is a system and method for multi-tenancy enablement of enterprise Java™ applications using resource proxies and application tenancy context. In according with an embodiment, the system and method can provide a plurality of deployable resources which can be used within the application server environment, and one or more application deployments, wherein each application deployment includes at least one of tenant-specific code and shared-tenant code. The system and method can further determine an application tenancy context of a thread, and point to one or more resource proxies, each of the one or more resource proxies being configurable to communicate with a tenant specific resource. Each of the one or more resource proxies can use the application tenancy context of a thread to communicate with a tenant specific resource.

Claims

1. A method for deployment of an application, comprising:

providing, at one or more computers, including an application server that enables deployment and execution of software applications, wherein the application server is associated with a domain configuration that is used at runtime to define a domain for execution of the software applications,

a plurality of application deployments within the application server, each application deployment being associated with a different tenant of a plurality of tenants, wherein an application deployment of the plurality of application deployments is associated with a tenant of the plurality of tenants, wherein the application deployment of the plurality of application deployments executes on a thread within the application server, and wherein the executing application communicates with a resource proxy;

determining an application tenancy context of the thread, the application tenancy context providing an indication of a tenant specific resource associated with the tenant; and

selecting by the resource proxy, based upon the determined application tenancy context of the thread, at least one tenant specific resource, of a plurality of tenant specific resources, associated with the tenant, wherein the resource proxy, on behalf of the executing application deployment, communicates with the selected at least one tenant specific resource associated with the tenant.

2. The method of claim 1, wherein the resource proxy further selects, based upon the determined application tenancy context, at least one global resource and communicates with the selected at least one global resource on behalf on the executing application deployment.

3. The method of claim 2, wherein a global application is provided, the global application configured to on-board at least one tenant of the plurality of tenants into the application server.

4. The method of claim 3, wherein one or more partitions are provided in the application server, and wherein the executing application deployment comprises an administrative subdivision and a runtime subdivision of a domain for use by the at least one on-boarded tenant.

5. The method of claim 4, wherein each partition is configured to host a different tenant of the plurality of tenants, wherein the global application is further configured to on-board the at least one tenant of the plurality of tenants into a partition of the plurality of partitions, and wherein each application deployment comprises at least one of shared-tenant runtime, tenant scoped runtime, and administrative runtime.

6. The method of claim 1, wherein determining the application tenancy context of the thread is based on at least a current application tenant.

7. The method of claim 1, wherein each of the plurality of application deployments further includes administrative code.

8. A system for deployment of an application, comprising:

one or more computers, including an application server that enables deployment and execution of software applications, wherein the application server is associated with a domain configuration that is used at runtime to define a domain for execution of the software applications; and

a plurality of application deployments within the application server, each application deployment being associated with a different tenant of a plurality of tenants, wherein an application deployment of the plurality of application deployments is associated with a tenant a plurality of tenants, wherein the application deployment of the plurality of application deployments executes on a thread within the application server, and wherein the executing application communicates with a resource proxy;

wherein the system determines an application tenancy context of the thread, the application tenancy context of providing an indication of a tenant specific resource associated with the tenant;

wherein the resource proxy, based upon the determined application tenancy context of the thread, selects at least one tenant specific resource, of a plurality of tenant specific resources, associated with the tenant, and, on behalf of the executing application deployment, communicates with the selected at least one tenant specific resource associated with the tenant.

9. The system of claim 8, wherein the resource proxy further selects, based upon the determined application tenancy context, at least one global resource and communicates with the selected at least one global resource on behalf on the executing application deployment.

10. The system of claim 9, wherein a global application is provided, the global application configured to on-board at least one tenant of the plurality of tenants into the application server.

11. The system of claim 10, wherein one or more partitions are provided in the application server, and wherein the executing application deployment comprises an administrative subdivision and a runtime subdivision of a domain for use by the at least one on-boarded tenant.

12. The system of claim 11, wherein each partition is configured to host a tenant of the plurality of tenants, wherein the global application is further configured to on-board the at least one tenant of the plurality of tenants into a partition of the plurality of partitions, and wherein each application deployment comprises at least one of shared-tenant runtime, tenant scoped runtime, and administrative runtime.

13. The system of claim 11, wherein the system determines the application tenancy context of the thread based on at least a current application tenant.

14. The system of claim 11, wherein each of the plurality of application deployments further includes administrative code.

15. A non-transitory machine readable storage medium having instructions stored there that when executed cause a system to perform the steps comprising:

providing, at one or more computers, including an application server that enables deployment and execution of software applications, wherein the application server is associated with a domain configuration that is used at runtime to define a domain for execution of the software applications,

a plurality of application deployments within the application server, each application deployment being associated with a different tenant of a plurality of tenants, wherein an application deployment of the plurality of application deployments is associated with a tenant of the plurality of tenants, wherein the application deployment of the plurality of application deployments executes on a thread within the application server, and wherein the executing application communicates with a resource proxy;

determining an application tenancy context of the thread, the application tenancy context of providing an indication of a tenant specific resource associated with the tenant; and

selecting by the resource proxy, based upon the determined application tenancy context of the thread, at least one tenant specific resource, of a plurality of tenant specific resources, associated with the tenant, wherein the resource proxy, on behalf of the executing application deployment, communicates with the selected at least one tenant specific resource associated with the tenant.

16. The non-transitory machine readable storage medium of claim 15, wherein the resource proxy further selects, based upon the determined application tenancy context, at least one global resource and communicates with the selected at least one global resource on behalf on the executing application deployment.

17. The non-transitory machine readable storage medium of claim 16, wherein a global application is provided, the global application configured to on-board at least one tenant of the plurality of tenants into the application server.

18. The non-transitory machine readable storage medium of claim 17, wherein one or more partitions are provided in the application server, and wherein the executing application deployment comprises an administrative subdivision and a runtime subdivision of a domain for use by the at least one on-boarded tenant.

19. The non-transitory machine readable storage medium of claim 18, wherein each partition is configured to host a tenant of the plurality of tenants, wherein the global application is further configured to on-board the at least one tenant of the plurality of tenants into a partition of the plurality of partitions, and wherein each application deployment comprises at least one of shared-tenant runtime, tenant scoped runtime, and administrative runtime.
