### Lightweight Web Application

#### Description

This pattern consists of 3 tiers (client, applications, and data) and reflects the architectural pattern implied by LAMP, the open source web platform highlighting a lightweight 2-tier backend.

#### Applicability

This pattern is ideally suited to environments with a moderate and fairly stable number of users. It is a simple architecture, so it’s easy to setup initially, but could prove difficult to maintain if many changes are required.
