Abstract

Various embodiments of systems and methods to provide processing of special requests at dedicated application containers are described herein. In one aspect, an application instance is downloaded and deployed in an application runtime, at a dedicated application container, to process service requests. In another aspect, the dedicated application container starts a proxy process, independently from the application runtime to intercept incoming service requests. The regular service requests are passed by the proxy process to the application runtime for processing by the executing application instance. In yet another aspect, the proxy process executes special service requests directly to access the dedicated container landscape.

Claims

1. A computer system to process special requests at dedicated application containers, the system comprising:

a memory to store computer executable instructions; and

a processor to execute the instructions stored in the memory to;

store, locally to a local file system of a dedicated container, artifacts of an application together with artifacts of an application runtime environment, wherein the application runtime environment to host an instance of the application;

deploy the application runtime environment and the instance of the application at the dedicated container, wherein the dedicated container provides a single end point to the instance of the application;

start a proxy at the dedicated container, in parallel to the application runtime environment;

intercept, by the proxy, an application request routed to the single end point, wherein the single end point provides direct access to the local file system of the dedicate container;

identify, by the proxy, whether the application request is special request; and

when the application request is determined as special request, process the application request by the proxy, separate from the application runtime environment, wherein processing the application requests includes;

accessing the local file system of the dedicated container; and

directly applying a change defined with the application request on a deployed application artifact without re-executing a full deployment cycle.

2. The system of claim 1, wherein the processor to execute the instructions stored in the memory further to:

intercept, by the proxy, a second application request routed to the single end point;

identify the second application request as regular application request; and

forward the second application request to the application runtime environment for processing by the instance of the application.

3. The system of claim 1, wherein starting the proxy comprises:

deploying the proxy at the dedicated container to run as an independent process.

4. The system of claim 1, wherein starting the proxy comprises:

deploying the proxy embedded in the application runtime environment.

5. The system of claim 1, wherein identifying the application request as special request comprises:

verifying that the application request includes an action specifying at least one of changing an artifact of the application, altering an environment variable of the dedicated container, and restarting the application runtime environment.

6. The system of claim 1, wherein identifying whether the application request is special request comprises:

recognizing the application request as special application request based on a parameter included in a routing string associated with the application request.

7. A non-transitory computer-readable medium to store instructions, which when executed by a computer, cause the computer to perform operations comprising:

deploy the instance of a cloud application at a cloud-based container, wherein the instance of the cloud application is deployed in an application runtime environment executing at the cloud-based container, and wherein the cloud-based container provides a single end point to the instance of the cloud application, and wherein artifacts of the cloud application together with artifacts of the application runtime environment are packaged together at a local file system of the cloud-based container, and wherein the single end point provides direct access to the local file system of the cloud-based container;

start a hot deployment proxy at the cloud-based container, in parallel to the executing application runtime environment;

intercept, by the hot deployment proxy, an application request routed to the single end point;

identify, by the hot deployment proxy, whether the application request is hot deployment request; and

when the application request is determined as hot deployment request, process the application request by the hot deployment proxy, separate from the application runtime environment, wherein processing the application requests includes;

accessing the local file system of the cloud-based container; and

directly applying a change defined with the application request on relevant deployed artifacts without re-executing a full deployment cycle.

8. The non-transitory computer-readable medium of claim 7 to store instructions, which when executed by the computer, cause the computer to perform operations further comprising:

intercept, by the hot deployment proxy, a second application request routed to the single end point;

identify the second application request as operation request; and

pass the second application request to the application runtime environment for processing by the instance of the cloud application.

9. The non-transitory computer-readable medium of claim 7, wherein deploying the instance of the cloud application comprises:

deploying the application runtime environment at the cloud-based container to host the instance of the cloud application.

10. The non-transitory computer-readable medium of claim 7, wherein starting the hot deployment proxy comprises:

deploying the hot deployment proxy at the cloud-based container to run as an independent process.

11. The non-transitory computer-readable medium of claim 7, wherein starting the hot deployment proxy comprises:
