Java applications are widely used and often several years old. You can use these applications in the cloud via lift-and-shift (helps nothing) or you can rewrite the application in cloud-native style and use the advantages of the cloud.

An alternative for existing applications is missing here. It must be possible to go to the cloud and use advantages such as serverless and scale-to-zero WITHOUT having to rewrite the entire application.

I will show what is already working well today and where the rough edges are. In the session, we'll move an existing application to the cloud and save over 70% of operating and maintenance costs with serverless and scale-to-zero.
