Deutsche Wolke (“German Cloud”) was founded to establish Federal Cloud Infrastructure in Germany.
This infrastructure will provide additional legal and security protections for hosted data. No longer will small businesses be exposed to the legal risk of losing their website presence without a trial (an unfortunate reality when doing business on transatlantic clouds).
The natural partner for backend storage infrastructure is LINBIT; as authors and maintainers of DRBD, we are best suited to provide the technical expertise to achieve High Availability. Also, DRBD Proxy is the obvious choice for off-site or disaster recovery replication (from the office into the cloud).
We at LINBIT look forward to seeing this project grow and prosper!
