This information in this repository is designed to help with WebSphere user's journey in application and operations modernization, to transition to Cloudpak for Applications and Openshift.
For administrators, the goals are:
- Present value of operations modernization from a WebSphere administrator's point of view.
- Explain new concepts and processes in Openshift
- Provide scenario-based guides that map scenarios in WebSphere to similar scenarios in Openshift.
- Provide corresponding scenario based hands-on labs to help WebSphere administrator become proficient in Openshift.
For application developers, the goals are:
- Present the value of application modernization.
- Introduce the user to microservices and new programming models such microprofile.
- Introduce the user to the Liberty and Open Liberty as the runtime for Java microservices.
- Provide scenario based guides on development and containerization with Liberty.
When available, you may use the material here for different venues:
- 1 - 2 hours presentation + short lab
- Half day workshop
- Full day workshop
- Potentially 2-day workshop
The administrator sections are:
