The following figure depicts the life cycle of a system in which a service platform is installed.
Figure 10-12 System life cycle of the Service Platform
The life cycle of a system in which a service platform is installed consists of the following phases:
- System design and service component preparation
- System configuration
- Setup
- Creation of various definitions and applications
- System operations
- System maintenance and review
The phases of this life cycle take place as described below.
- System design and service component preparation
After you decide to install the service platform, analyze the business operations to be executed in the system and convert the business applications into services. Design the system according to how the services are to be used.
- System configuration
Configure the development environment, the operating environment, and the execution environment based on the design information and service component information of the system decided upon in step 1.
- Setup
Prepare to start system operations by setting up the operating and execution environments. In addition to the design information and service component information of the system devised in step 1, also use the definition information and applications that were created in the development environment.
- Creation of various definitions and applications
Develop the various definitions and applications required to operate the system.
In developing the definitions and applications, use the setup information of the operating and execution environments, in addition to the application design information and service component information devised in step 1.
- System Operations, Maintenance, and Review
Start system operations. During system operations, perform daily operations as well as periodic system maintenance.
Review the system any time business operations need to be modified, or when the system scale needs to be changed. After reviewing the system, if you decide to reconfigure it and set it up again, or add or modify certain definitions and applications, carry out the procedures described in steps 2 to 4 before restarting system operations.
Continue this process until you decide to renew or discontinue use of the service platform.
The following subsections provide an overview of the various stages (procedures).
