Introducing Cloudsync

Operating Environment

Cloudsync uses a hub-and-spoke topology. The source database, at the "hub," holds the master copy of the database objects. All administration is handled at the source. The source typically runs as a server. See the Cloudscape Server and Administration Guide for more details.

A target database, on a "spoke," holds a copy of the source database (or a subset of the database). Targets are designed for non-technical end users and require no local administration. Targets are typically embedded in an application; the user of the target application may not even be aware of the database. Cloudsync can also distribute and update the target application itself. A target can run on almost any computing device that contains a Java Virtual Machine (JVM).
