For this guide you need only a laptop or PC with JDK8 and WLS12.1.3 already installed. (WLS is not mandatory but recommended)
If you are not interested on deploying the application on Java Cloud Service, you must follow only the task 3, 6
- you will need a pub key for the creation of a new service in Oracle Java Cloud Service
- you will need a ppk key for ssh communication from your laptop to Java Cloud Service
This is a "pessimistic" Gantt, but it is an idea of what to do during the waiting time of the creation of Java Cloud Service, but as you can see, in around 4 hours (I was able to do this in 2 hours) you will be able to create an Hybrid DevOps architecture from scratch. (Task "Porting Application" is out of the scope of this guide).
Obviously for a new project you will spend few seconds, with Oracle Cloud Plug-in inside Eclipse, you will able to create a new project on premise and on cloud and synchronize it in a simple way.
