 +Vertical scaling: essentially adding more hardware ressources to the same machine (i.e., more and faster processors, memory and disk).

 +  * Expensive
 +  * Simple
 +  * Single point of failure
  
 We must ensure that WDB scales vertically with the hardware; i.e., increasing capacity by upgrading hardware specifications, while maintaining the physical footprint and number of servers in the server farm. Scaling hardware vertically simplifies site management, but at a higher hardware cost than scaling horizontally or improving software architecture. In addition, once you reach maximum capacity on existing hardware, you must begin to scale horizontally. We must ensure that WDB scales vertically with the hardware; i.e., increasing capacity by upgrading hardware specifications, while maintaining the physical footprint and number of servers in the server farm.

 +    * Cheap(er)

 +We would like to construct a framework for WDB that scales horizontally on the hardware; i.e., it should be possible to add new servers to our existing infrastructure and have it seamlessly improve performance of reads and (maybe) writes.
