Exposing mainframe applications/modules to front end Java or other web applications is booming today.
Switching from one process to another, the first thing what we need to do is:
- Cost-benefit analysis
Many big organizations have a thought in their mind to use mainframe modules with web applications.
There are multiple reasons switching to Webservices:
- Front end web applications are attractive
- Portable to internet and it can be accessed through worldwide on internet
- Good scalability
- New web applications are good latest features as suitable to ne w generation
- Less expensive compared to mainframe/AS400
There are two ways we can expose mainframe modules to webservices
- CICS WebServices
- EGL WebServices
Basic idea behind is:
We extract the code from the existing application and make it a stand-alone component that can then be used by both the existing 3270-based application, as well as the new Web-based application. We can then refactor our ordering system using IBM Asset Transformation Workbench, IBM Rational Developer for System z and IBM Enterprise COBOL.
