Abstract

Techniques provide include analyzing a first node, associated with a first version of an service, to extract first configuration metadata; analyzing the first node, associated with a second version, subsequent to the first version, of the aservice, to extract second configuration metadata; determining, based upon a comparison of the first configuration metadata and the second configuration metadata, that the first node has not been modified between the first version and the second version; generating a first image of the node for distribution in conjunction with the service in response to the determining that the particular node has not been modified; and caching the first image for use in conjunction with the service.

Claims

1. A method, stored as program code on a non-transitory computer-readable storage medium, the program code executable by a plurality of processors, the method comprising:

analyzing a first cloud node, associated with a first version of a service, to extract first configuration metadata;

analyzing the first cloud node, associated with a second version, subsequent to the first version, of the service, to extract second configuration metadata;

determining based upon a comparison of the first configuration metadata and the second configuration metadata, that a first application package common to the first cloud node and the second cloud node has not been modified between the first version and the second version;

generating a first cloud image of the first application package in response to the determining that the particular software package has not been modified; and

caching the first cloud image for distribution in response to a request for deployment of the service.

2. The method of claim 1, the determining that the first application package has not been modified between the first version and the second version comprising determining that a change in the first application package between the first version and the second version is less than a threshold amount of change.

3. The method of claim 1, further comprising:

determining, based upon a comparison of the first configuration metadata and the second configuration metadata, that a second application package common to the first cloud node and the second cloud node has been modified between the first version and the second version; and

distributing the second software package in conjunction of the service in response to the determining that the second application package has been modified.

4. The method of claim 1, further comprising:

determining, based upon a comparison of the first configuration metadata and the second configuration metadata, that a second application package common to the first cloud node and the second cloud node has been modified more than a threshold amount of change between the first version and the second version; and

distributing the second software package in conjunction of the service in response to the determining that the second application package has been modified more than the threshold amount of change.

5. The method of claim 1, further comprising:

analyzing the first cloud node, associated with a third version, subsequent to both the first and second version, of the service, to extract third configuration metadata;

determining, based upon a comparison of the second configuration metadata and the third configuration metadata, that the first software package of the first cloud node has been modified between the second version and the third version;

generating a second cloud image of the first software package in response to the determining that the first software package has been modified;

caching the second cloud image for distribution in response to a request for deployment of the service; and

deleting the cached, first cloud image.

6. The method of claim 5, the determining, based upon a comparison of the second configuration metadata and the third configuration metadata that the first software package of the first cloud node has been modified between the second version and the third version, comprising determining that a change in the first portion between the second version and the third version exceeds a threshold amount of change.

7. The method of claim 1, wherein the software application may be any of a list of computing entities, the list of computing entities comprising:

an operating system;

a web application server;

a middleware;

a database server;

a reverse proxy;

a native library;

a web application; and

a web application archive (WAR) file.

8. The method of claim 1, further comprising receiving the first cloud node from a deployment test environment for the application.

9. The method of claim 8, further comprising generating, with a source control system, the service in the deployment test environment.

10. An apparatus, comprising:

a processor;

a non-transitory, computer-readable storage medium coupled to the processor; and

logic, stored on the computer-readable storage medium and executed on the processor, for;

analyzing a first cloud node, associated with a first version of a service, to extract first configuration metadata;

analyzing the first cloud node, associated with a second version, subsequent to the first version, of the service, to extract second configuration metadata;

determining, based upon a comparison of the first configuration metadata and the second configuration metadata, that a first application package common to the first cloud node and the second cloud node has not been modified between the first version and the second version;

generating a first cloud image of the first application package in response to the determining that the particular software package has not been modified; and

caching the first cloud image for distribution in response to a request for deployment of the service.
