ScaleDB operates on all Linux-based public clouds tested thus far. There are certain optimizations that are advantageous for ScaleDB including: running instances on different machines for high-availability, fast interconnects, block storage, etc. We have jointly tested and approved ScaleDB on the following clouds: HP Cloud, Amazon, Rackspace and Verizon/Terremark. We continue to test ScaleDB on more and more clouds. Our goal is that ScaleDB run smoothly on every public Linux cloud. Our experience thus far is that we are accomplishing this goal.
MySQL is the most popular, some might say dominant, cloud database in the world. Yet MySQL is not particularly cloud-friendly. The core of cloud technology is virtualization, yet MySQL is not virtualized. ScaleDB changes this, turning MySQL into a virtualized and cloud-friendly database. This enables cloud to enjoy the same benefits on the database tier as they do on the application tier, namely: simplified management, instance mobility, modularity, elasticity, and more.
