Using service catalogs
Implementation of a service catalog
In HOPEX IT Architecture, a service catalog is made up of service catalog item. For example, an information service catalog is made up of several information service catalog items.
An information service catalog provides a centralized information source for the information services offered by the service provider organization. It contains a customer-oriented view of the information services used, how they are supposed to be used, the processes that they support as well as the expected service quality level. The information service catalog presents the list of functionalities mentioned as well as implementation recommendations.An information service catalog item defines which functionality is in the catalog and which application artifacts provide the functionality.A service catalog item is connected to one or more functionalities.
A technical functionality is a capability expected from an equipment item (hardware or software) to ensure the operation of a technical element or an application.With HOPEX IT Architecture, the implementation of a functionality is represented by an Implementation.
An implementation describes the relationship between a logical entity and a physical entity that implements it. The physical entity gives the list of logical entities that it implements.The table below draws up the summary of objects that implement the service catalogs according to their category.
Type of service catalog | Type of functionality | Types of object that deliver the service |
|---|---|---|
Business | Features | Business capability |
Information | Features | All types of technical and functional objects that implement a functionality with HOPEX IT Architecture. For more details, see Describing a Functionality Map with HOPEX IT Architecture. |
Technical | Technical functionalities | All types of technical objects that implement a functionality with HOPEX IT Architecture: technical infrastructures, equipment and IT infrastructures, micro services, deployment packages, all IT equipment (servers, networks, devices). |
hardware | Hardware functionalities | Hardware and IoT Device. |
Populating a service catalog
The management principle of a service catalog is identical for all types of service catalogs. The types of service catalogs offered are:
• business service catalogs,
A business service catalog provides a centralized information source for the business services offered by the service provider organization. It contains a customer-oriented view of the services associated to business capabilities, how they are supposed to be used, the processes that they support as well as the expected service quality level. The business service catalog presents the list of functionalities mentioned as well as implementation recommendations.• information service catalogs,
An information service catalog provides a centralized information source for the information services offered by the service provider organization. It contains a customer-oriented view of the information services used, how they are supposed to be used, the processes that they support as well as the expected service quality level. The information service catalog presents the list of functionalities mentioned as well as implementation recommendations.• technical service catalogs,
A technical service catalog provides a centralized information source for the technical services offered by the service provider organization. It contains a customer-oriented view of the technical services used, how they are supposed to be used, the processes that they support as well as the expected service quality level. The technical service catalog presents the list of IT functionalities mentioned as well as implementation recommendations.• hardware service catalogs.
A hardware service catalog provides a centralized information source for the hardware services offered by the service provider organization. It contains a customer-oriented view of the hardware used, how they are supposed to be used, the processes that they support as well as the expected service quality level. The hardware service catalog presents the list of hardware functionalities mentioned as well as implementation recommendations.This chapter is based on the example of an information service catalog.
Creating an information service catalog
To create an information service catalog:
1. From the Inventories navigation pane, select Service Catalogs.
2. Click the Information Services Catalogs tile.
The list of information service catalogs appear in the edit area.
3. Click New.
A new information service catalog appears in the edit area.
4. Enter the Name of your catalog and its Owner.
In the same way, you can create a technical service catalog or a hardware service catalog.Adding a service catalog item
The Characteristics property page of a service catalog provides access to:
• its Owner, by default, during creation of the logical application system, the current library.
• its Name,
• To access the list of service catalog items owned:
To add an information service catalog item:
1. Open the Characteristics properties page of an information service catalog.
2. In the Information Service Catalog items section, click New.
In the window that opens, you can select an existing functionality or create a new one.
3. Select the functionality that interests you and click OK.
The catalog element appears in the list with the name of the associated functionality.
Specifying the implementation of a service catalog item
To describe all the Service Catalog elements that implement a functionality, you will define a Realization.
An implementation describes the relationship between a logical entity and a physical entity that implements it. The physical entity gives the list of logical entities that it implements.To describe that a functionality is implemented by a Service Catalog element:
1. Open the Characteristics property page of an information service catalog.
2. In the Information Service Catalog items section owned, click New.
An add functionality dialog box appears:
3. Select the functionality that interests you.
4. Click OK.
The functionality realization appears in the properties page.
Service catalog reports
With a report, you can determine, for a list of service catalogs, the list of functionalities covered, and for each of them, the implementation means.
Report parameters
This consists of defining report input data.
Parameters | Parameter type | Constraints |
|---|---|---|
List of service catalogs | All types of service catalogs: - information, - technical, - hardware. | A mandatory catalog. |
Accessing a service catalog report
To access a service catalog report:
1. Open the Reports property page of a service catalog.
2. In the Parameters section, select the service catalogs that you want to present in your report.
3. Click Refresh the Report.
The new report appears.
