Multi-Tier Pattern
In the multi-tier pattern, runtime structures are organized into logical groups. These logical groups may be allocated to specific physical components, such as a server or cloud platform. The multi-tier pattern is conceptually similar to the layers pattern. Layers are a module structure and deal with design-time elements, whereas tiers are either a component and connector or allocation structure and deal with runtime elements.
Any system in which components will live on different platforms or hardware will benefit by thinking about the tiers at play and which components reside on different tiers. See the table.
