Abstract

A deployment system enables a developer to customize a deployment plan generated according to a logical, multi-tier application blueprint for deploying multiple applications in a cloud infrastructure. Using the deployment system, the developer inserts a custom script or task in a sequence of tasks to be performed to deploy an application component in different phases (e.g., installation, configuration, start-up) on a virtual machine. The deployment system anchors the custom script to the different phases of the application component's deployment such that the customizations to the deployment plan are maintained through changes to the underlying application blueprint.

First claim

We claim:

1. A method for modifying a deployment plan having tasks that are performed to deploy an application having one or more application components executing on a plurality of virtual computing resources, the method comprising the steps of:
receiving, by a processor, a first script and a first placement location for the first script in a first sequence of tasks that are performed to deploy the one or more application components of the application;
receiving, by the processor, a second script and a second placement location for the second script in a second sequence of tasks that are performed external to and not in conjunction with deploying any of the one or more application components of the application; and
generating, by the processor, a modified deployment plan having the first and second sequences of tasks that are performed to deploy the application according to a topology of the plurality of virtual computing resources and the one or more application components of the application executing thereon, wherein the modified deployment plan includes:
the first script for execution at the first placement location in the first sequence of tasks, and
the second script for execution at the second placement location in the second sequence of tasks.

2. The method of claim 1 , wherein the step of receiving the first script further comprises:
selecting the first script from a library of user-defined scripts; and
receiving modifications to the selected first script comprising at least one reference to a configuration property defined for one of the one or more application components of the application.

3. The method of claim 1 , wherein the step of receiving the first script further comprises:
receiving an input through a graphical user interface that implements drag-and-drop functionality in a region showing the first sequence of tasks as a plurality of connected icons, wherein the input identifies the first script and indicates the first placement location in the first sequence of tasks for the first script.

4. The method of claim 3 , further comprising:
receiving another input through the graphical user interface to reorder the first sequence of tasks, wherein the modified deployment plan is generated to include execution of the first sequence of tasks as reordered.

5. The method of claim 1 , further comprising:
determining a change to the topology of the plurality of virtual computing resources and the one or more application components of the application from which the modified deployment plan is generated; and
generating a corresponding change to the modified deployment plan while preserving the first script at the first placement location in the first sequence of tasks.

6. The method of claim 5 , wherein the change to the topology of the plurality of virtual computing resources is a deletion of one of the one or more application components of the application, and wherein the received first script is anchored to a task that is performed to deploy another one of the one or more application components of the application.

7. The method of claim 5 , wherein the change to the topology of the plurality of virtual computing resources is a change in a dependency from a first application component to a second application component of the application, and wherein the received first script is anchored to the first application component of the application such that the received first script reorders along with the first sequence of tasks for deploying the first application component of the application.

8. A non-transitory computer-readable storage medium storing instructions that, when executed in a computing device, modify a deployment plan having tasks that are performed to deploy an application having one or more application components executing on a plurality of virtual computing resources, by performing the steps of:
receiving a first script and a first placement location for the first script in a first sequence of tasks that are performed to deploy the one or more application components of the application;
receiving a second script and a second placement location for the second script in a second sequence of tasks that are performed external to and not in conjunction with deploying any of the one or more application components of the application; and
generating a modified deployment plan having the first and second sequences of tasks that are performed to deploy the application according to a topology of the plurality of virtual computing resources and the one or more application components of the application executing thereon, wherein the modified deployment plan includes:
the first script for execution at the first placement location in the first sequence of tasks, and
the second script for execution at the second placement location in the second sequence of tasks.

9. The non-transitory computer-readable storage medium of claim 8 , wherein the instructions to perform the step of receiving the first script further comprise instructions to perform the steps of:
selecting the first script from a library of user-defined scripts; and
receiving modifications to the selected first script comprising at least one reference to a configuration property defined for one of the one or more application components of the application.

10. The non-transitory computer-readable storage medium of claim 8 , wherein the instructions to perform the step of receiving the first script further comprise instructions to perform the step of:
receiving an input through a graphical user interface that implements drag-and-drop functionality in a region showing the first sequence of tasks as a plurality of connected icons, wherein the input identifies the first script and indicates the first placement location in the first sequence of tasks for the first script.

11. The non-transitory computer-readable storage medium of claim 10 , further storing instructions that, when executed in the computing device, perform the step of:
receiving another input through the graphical user interface to reorder the first sequence of tasks, wherein the modified deployment plan is generated to include execution of the first sequence of tasks as reordered.

12. The non-transitory computer-readable storage medium of claim 8 , further storing instructions that, when executed in the computing device, perform the steps of:
determining a change to the topology of the plurality of virtual computing resources and the one or more application components of the application from which the modified deployment plan is generated; and
generating a corresponding change to the modified deployment plan while preserving the first script at the first placement location in the first sequence of tasks.

13. The non-transitory computer-readable storage medium of claim 12 , wherein the change to the topology of the plurality of virtual computing resources is a deletion of one of the one or more application components of the application, and wherein the received first script is anchored to a task that is performed to deploy another one of the one or more application components of the application.

14. The non-transitory computer-readable storage medium of claim 12 , wherein the change to the topology of the plurality of virtual computing resources is a change in a dependency from a first application component to a second application component of the application, and wherein the received first script is anchored to the first application component of the application such that the received first script reorders along with the first sequence of tasks for deploying the first application component o
