I don’t have much experience in this yet but the high level question that I have is this: We have an Oracle database that our old WIN32 applications are using it to query its tables and do stuff.Now we are developing a webapp with Java, Cloud, etc…Now what are the technologies, architectures, tools, etc… available that can help me use the same Oracle tables and data this but time in the Cloud, so I can query them, show some cool graphs, update its tables, etc… Thank you very much for any help that shows me the road …

This question is a little hard to follow, so I hope I am answering in the vein of what you are trying to ask.
You’d use the same tools you always use to do that stuff, the cloud is just a matter of moving some of your app to a remote server over the Internet. Assuming you are keeping the Oracle database local you would just need to set up some kind of hybrid or private cloud so that the machines can see each other over IP. You really don’t need to use different tools, just re-architect the communication layer between them.
TL:DR – Look up terms like Virtual Private Cloud and Hybrid Cloud. These let you have cloud resources that are (virtually) on your local network, then you just do everything the same way you normally would.
