News in the OpenStack space hasn’t been so good recently (Intel pulling out of OSIC, various companies laying off folks, other “pure play” companies shifting focus away from OpenStack), but here’s one architect’s perspective on what you may still want to attend the OpenStack Summit. Operating Systems/Applications.

As opposed to just encrypting data at the transport level (although Acra does that between components of its architecture) or just encrypting data at the storage level (using an encrypted file system or similar), Acra targets encrypting data at the table/row/column level within a database. Acra is open source and available via GitHub.

Calderon: And even when we wrote the book it got tricky because some of the cool findings that we had, couldn't be mentioned in the book so we had to you know work on open source boards and come up, use open source laboratories instead of doing real life examples. And it's not just stories from the authors themselves.
