Policy management of deployment plans
View Patent ↗A deployment system enables a developer to define a logical, multi-tier application blueprint that can be used to create and manage (e.g., redeploy, upgrade, backup, patch) multiple applications in a cloud infrastructure. The deployment system supports the use of nested policies to manage a deployment plan. Upon determining compliance to the nested policies, the application can be deployed according to an application blueprint, which means any needed VMs are provisioned from the cloud infrastructure, and application components and software services are installed.
1. A method for deploying an application, the method comprising:
receiving a deployment plan comprising a nested object having a plurality of levels, wherein the nested object comprises at least one level selected from the group of levels representing a deployment plan, a deployment environment, and a cloud computing environment;
for each level, retrieving a policy having a domain object that matches a current level of the nested object and determining a next level of the nested object until no next level exists, wherein the one or more retrieved policies comprises a script accessing information about the deployment plan from the nested object, wherein the nested objected is a data structure of a first programming language exposed to the policy that is written in a second programming language;
determining compliance of the deployment plan to the one or more retrieved policies; and
executing, by a computer processor, the deployment plan to deploy the application in a cloud environment responsive to determining compliance.
2. The method of claim 1 , wherein determining the compliance of the deployment plan to the one or more retrieved policies comprises:
executing the one or more retrieved policies.
3. The method of claim 1 , wherein the nested object comprises a plurality of domain objects configured to support an interface that retrieves a parent of the respective domain object.
4. The method of claim 1 , wherein determining the next level of the nested object comprises invoking a class method of the nested object configured to get a parent of the nested object.
5. A non-transitory computer-readable storage medium comprising instructions that, when executed in a computing device, for deploying an application, by performing the steps of:
receiving a deployment plan comprising a nested object having a plurality of levels, wherein the nested object comprises at least one level selected from the group of levels representing a deployment plan, a deployment environment, and a cloud computing environment;
for each level, retrieving a policy having a domain object that matches a current level of the nested object and determining a next level of the nested object until no next level exists, wherein the one or more retrieved policies comprises a script accessing information about the deployment plan from the nested object, wherein the nested objected is a data structure of a first programming language exposed to the policy that is written in a second programming language;
determining compliance of the deployment plan to the one or more retrieved policies; and
executing the deployment plan to deploy the application in a cloud environment responsive to determining compliance.
6. The non-transitory computer-readable storage medium of claim 5 , wherein determining the compliance of the deployment plan to the one or more retrieved policies comprises:
executing the one or more retrieved policies.
7. The non-transitory computer-readable storage medium of claim 5 , wherein the nested object comprises a plurality of domain objects configured to support an interface that retrieves a parent of the respective domain object.
8. The non-transitory computer-readable storage medium of claim 5 , wherein determining the next level of the nested object comprises invoking a class method of the nested object configured to get a parent of the nested object.
9. A computer system for deploying an application, the computer system comprising:
a system memory comprising a program; and
a processor configured to execute the program and carry out the steps of:
receiving a deployment plan comprising a nested object having a plurality of levels, wherein the nested object comprises at least one level selected from the group of levels representing a deployment plan, a deployment environment, and a cloud computing environment;
for each level, retrieving a policy having a domain object that matches a current level of the nested object and determining a next level of the nested object until no next level exists, wherein the one or more retrieved policies comprises a script accessing information about the deployment plan from the nested object, wherein the nested objected is a data structure of a first programming language exposed to the policy that is written in a second programming language;
determining compliance of the deployment plan to the one or more retrieved policies; and
executing the deployment plan to deploy the application in a cloud environment responsive to determining compliance.
10. The computer system of claim 9 , wherein determining the compliance of the deployment plan to the one or more retrieved policies comprises:
executing the one or more retrieved policies.
11. The computer system of claim 9 , wherein the nested object comprises a plurality of domain objects configured to support an interface that retrieves a parent of the respective domain object.
12. The computer system of claim 9 , wherein determining the next level of the nested object comprises invoking a class method of the nested object configured to get a parent of the nested object.
