An IT shop has a service template that accepts 8 input parameters. Each user can watch as the blueprint processor displays the status for creation of each resource.Īnother example illustrates the use of a blueprint to address simplicity and consistency concerns. One person authors a blueprint so that all QA engineers can simply invoke the blueprint and enter a few input parameter values, after which the resources are created. Instead of manually creating the service instances using the Enterprise Manager Cloud Self Service application, a blueprint can be used to perform this task. To summarize, blueprints allow you to automate the creation of a set of service instances.įor example, the Quality Assurance team in an enterprise needs to allocate and release resources required to test a Web application. To create a textual representation that can be reviewed and modified by other users. To eliminate the manual interactive steps that would otherwise be needed to create the set of instances To facilitate instance creation for other EM_SSA_USERS. To create such sets of instances several times. To create an application composed of several service instances and related cloud resources. An EM_SSA_USER can use blueprints for various reasons: You can also refer to the Chapter 58, "Cloud Blueprints and Blueprint Reference"for more details on blueprints.Ī blueprint can be used to automate the creation of service instances. The rest of this chapter introduces the blueprint concepts including how to deploy an existing blueprint as well as how to write your own. The blueprint initiates the creation of the resources and monitors the creation process to ensure that the dependent resources are automatically created as soon as the required resources are created. To do so, you request instantiation of the blueprint and provide any input parameter values required by the blueprint. When both the WebLogic server and database are created, you could create the JEE datasource.Īlternatively, you can use a blueprint that describes the four cloud resources to automate the process. Once the WebLogic server is created, you could deploy the application. Periodically, you would check the status of the creation requests. You would request creation of the WebLogic server and database and wait for either to complete. You could perform all these operations manually, through the Enterprise Manager Cloud Self Service Portal. To do so, you must first create the database and WebLogic server instance, deploy the application, and create a JEE datasource that is to be used by the WebLogic server to connect to the database. Rather, the blueprint orchestration logic figures that out based on inter-resource dependencies.Īs an example, suppose you want to create a set of interacting cloud resources such as a WebLogic server instance, an application, and a database. For instance, a blueprint does not describe the order in which to create the components. Like architectural blueprints, they describe what you want including how they are configured to interact with each other, but not how to build them. Blueprints are used to describe a desired set of inter-related cloud resources.
