2. Description of the Related Art
Component-based software engineering is a branch of software engineering that emphasizes the separation of concerns in respect of the wide-ranging functionality available throughout a given software system. An individual component is a software package or a module that encapsulates a set of related functions or data. All system processes are placed into separate components so that all of the data and functions inside each component are semantically related. Because of this principle, it is often said that components are modular and cohesive. With regard to system-wide co-ordination, components communicate with each other via interfaces. When a component offers services to the rest of the system, it adopts a provided interface which specifies the services that can be utilized by other components and how. This interface can be seen as a signature of the component—the client does not need to know about the inner workings of the component (implementation) in order to make use of it. This principle results in components referred to as encapsulated.
Components generally execute within a container provided by an application server. Different components can depend upon the presence of other components and resourced within a container. Consequently, deploying a component based application to a target environment mandates the presence of all dependencies requisite to the operation of the component based application, and also the proper selection of a container version, and yet further a proper configuration of the container and perhaps the application server and supporting host computer, itself. The complexity then of deploying a component based application to a target environment far exceeds that of the deployment of traditional binaries to a personal computer or server.
To address the complex nature of deploying a component based application to multiple different target environments, developers often formulate deployment scripts intended to partially automate the deployment process. The development of a deployment script, in of itself, can be complicated and costly, however. Further, the development of the deployment script can be closely related to the subject component based application to be deployed and thus, every application to be deployed enjoys its own, custom developed deployment script—an enormously inefficient outcome.
Embodiments of the present invention address deficiencies of the art in respect to deployment script development and provide a novel and non-obvious method, system and computer program product for model driven deployment of component based applications. In an embodiment of the invention, a method for model driven deployment of component based applications can include selecting units representative of corresponding programmatic objects to be deployed into a target environment and specifying a deployment topology for the target environment. The method also can include matching portions of the units to different automation signatures and filtering the different automation signatures to a set of automation signatures based upon the deployment topology. The set of automation signatures can be ordered according to known dependencies of a corresponding deployment model and the ordered set of automation signatures can be bundled into an automation workflow and published to an automation engine for execution to deploy the programmatic objects into the target environment.
In another embodiment of the invention, a deployment data processing system can be configured for model driven deployment of component based applications. The system can include a host server with at least one processor and memory, coupled to different target environments over a computer communications network. The system also can include a data store of one or more databases coupled to the host server that includes automation signatures and units individually representative of underlying programmatic objects. Of note, each automation signature can include a deployment model, a parameter list of parameters bound to elements in the deployment model, and a script identifier identifying a script operative to deploy a specified programmatic object to a target environment using parameters set forth in the parameter list.
Finally, the system can include a development environment executing in the memory of the host server and a model drive deployment module coupled to the development environment. The module can include program code enabled to match portions of selected ones of the units to different automation signatures, to filter the different automation signatures to a set of automation signatures based upon an established deployment topology, to order the set of automation signatures according to known dependencies of a corresponding deployment model, and to bundle the ordered set of automation signatures into an automation workflow and publish the automation workflow to an automation engine for execution to deploy the programmatic objects into a selected one of the target environments.
Additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The aspects of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.
The accompanying drawings, which are incorporated in and constitute part of this specification, illustrate embodiments of the invention and together with the description, serve to explain the principles of the invention. The embodiments illustrated herein are presently preferred, it being understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown, wherein:
Embodiments of the invention provide for model driven deployment of component based applications. In accordance with an embodiment of the invention, different automation signatures can be established, each including a deployment model for deploying a program object to a target environment, a list of parameters for the deployment, a corresponding set of bindings between the parameters and elements of the deployment model, and a script identifier identifying a programmatic script operative to deploy the program object to the target environment with the parameters of the list. Different unit representations of underlying program objects can be mapped to corresponding ones of the automation signatures and the mapped automation signatures further can be limited to a set of automation signatures compatible with a deployment topology for a specified target environment. Thereafter, the set of automation signatures can be ordered according to known dependencies between the respective deployment models and packaged in an automation workflow. Finally, the automation workflow can be published to an automation engine for execution in deploying the program objects into the target environment.
In further illustration,
A deployment topology 150 can be described for a target environment 190 into which one or more components 180 are to be deployed. The components 180 can be represented in the abstract by corresponding units 160. Model driven deployment logic 300 can match each of the units 160 to one or more of the automation signatures 110 by reference to the respective deployment models 120 and parameter lists 130 consistent with the requirements of the units 160. A deployment topology 150 can be specified for the target environment 190 and can be used by the model driven deployment logic 300 to filter the matched ones of the automation signatures 110 to a set of automation signatures 110 suitable for deploying the corresponding components 180 to the target environment 190.
Thereafter, the set of automation signatures 110 can be ordered according to known dependencies of the respective deployment models 120 and packaged into an automation workflow 170. Finally, execution of the automation workflow 170 can result in the execution of the programmatic scripts referenced by the script identifiers 140 of the ordered set of automation signatures 110 in order to deploy the components 180 into the target environment 190. In this way, the process of deploying components into a target environment can be both automated while remaining extensible so as to gain efficiencies in the use and reuse of deployment scripts for component based applications.
The process described in connection with
The host server 210 can include at least one processor and memory and can support the operation of a development environment 240 in which model driven development of deployment scripts can be performed. A model driven deployment module 300 further can be coupled to the development environment 240 and can be accessed through graphical user interface 290 in communicatively linked computer 200. Through the graphical user interface 290, an end user can direct the model driven deployment module 300 to generate and publish an automation workflow 280 to an automation engine 270 which in turn can execute the automation workflow 280 to deploy a component based application to one or more of the target environments 220.
In particular, the model driven deployment module 300 can include program code that when executed by the host server 210 can match a selected set of units 260B to one or more of the automation signatures 260A. The program code of the model driven deployment module 300 further can be enabled upon execution to reduce the matched automation signatures 260A according to an established deployment topology of a target environment. Thereafter, the reduce set of automation signatures 260A can be ordered according to known dependencies therebetween and bundled into an automation workflow 280. Finally, the program code of the model driven deployment model 300 can be enabled to publish the automation workflow 280 to the automation engine 270 for execution in deploying underlying program objects into a target one of the target environments 220.
In yet further illustration of the operation of the model driven deployment module 300,
In block 350, the filtered set of automation signatures can placed into an automation workflow and in block 360, the automation signatures in the automation workflow can be ordered according to known dependencies set forth in the deployment models of the different automation signatures. Optionally, automation signatures in the set able to be executed simultaneously with other automation signatures in the set can be specified. In block 370, the automation workflow can be published to an automation engine configured to deploy the application. As yet another option, the automation workflow can be published to multiple different automation engines for coordinated execution. Finally, as an option, in block 380 one or more different configuration files can be generated for the automation workflow according to different target environments so as to afford reuse of the same automation workflow across the different target environments.
