Understand some options is the key
With the availability of relatively inexpensive, high-powered processors, memory, and disk drives, there is a temptation to buy more system resources to improve performance. New CPUs, memory, or more disk drives can provide immediate performance improvement in many situations. However, any performance increases achieved by adding hardware should be considered a short-term relief to an immediate problem.
Data Architecture
Today’s designers and architects are responsible for sizing and capacity planning of hardware at each tier in a multitier environment. It is the architect’s responsibility to achieve a balanced design. This is analogous to a bridge designer who must consider the bridge’s various payload and structural requirements.
