Open Source DataTurbine (http://dataturbine.org/, based on the patented Ring-buffered Network Bus (RBNB) technology) is a real-time server which stores and synchronizes access to channels of data. As a predecessor to CloudTurbine, DataTurbine and CloudTurbine share similar design principles, namely that any type of data can be stored and there is seamless integration between streaming real-time and playback data. Leveraging advances in computer hardware and the proliferation of third-party file sharing services and cloud-based technology, CloudTurbine has taken a “micro-kernel” approach to advance the DataTurbine concept: there is no central server and the technology is focused on writing open, incremental archive data files. The table below compares some of the features of these technologies.
| DataTurbine | CloudTurbine | |
|---|---|---|
| central server | yes, proprietary | no |
| archive format | custom, proprietary | open format, incremental self-describing files |
| data mirroring & distribution | built-in | use 3rd-party file sharing services; built-in support for FTP |
| latency | < 1msec | 10ms – 1+sec (depending on file-sharing service) |
| HTTP support | Tomcat server, WebScan | CTweb, WebScan |
| administration | moderate (networking and memory issues) | low (3rd-party file-sharing service handles the details) |
| API | Java-based | Java-based |
