What is the current approach to the data center computer architecture scalability?
A. scale in
B. scale out
C. scale down
D. scale up
Correct Answer: A
Explanation/Reference:
As the data center computing architecture evolves toward a scale-in approach, server scalability challenges must be addressed. Each server has a limited amount of resources in terms of processor, memory, or I/O throughput. Depending on resource availability, a server can run either one or several applications. Regardless of the server power and resource capacity, eventually these limitations are reached. Furthermore, not every server type is optimal for different applications. The question becomes, then, how do we increase the data center’s computing power?
