SWITCHdrive

The popular Sync & Share service SWITCHdrive is running on the SWITCHengines infrastructure. A cluster of 12 virtual machines provide database, file-storage, backup, directory, monitoring, application and web services. 

This flexible solution allows us to scale the number of servers to the changing load of users, always keeping an optimum of servers running at any time. Adding a new server can be done within minutes. 

The SWITCHdrive servers serve about 10'000 users with around 20 TB of data stored (numbers as of mid 2015).

SWITCHdrive is an example of a highly scalable web application, running fully virtualized in the cloud.
