Design considerations for n-tier architecture

The following are some of the scenarios in which n-tier architecture is a good choice:

• If you are architecting a system in which it is possible to split the application logic into smaller components that could be spread across several servers. This could lead to the design of multiple tiers in the application tier.
• If the system under consideration requires faster network communications, high reliability, and great performance, then n-tier has the capability to provide that as this architectural pattern is designed to reduce the overhead which is caused by network traffic.
