Multi-tier architecture

For a given custom application, multiples of any of these tiers may be used thus n-tier. There is no implied relationship between tiers and machines, but collapsing all the tiers onto a single machine would not be network centric.

1. Client Tier

2. Web Tier

3. Application Tier

4. Database Tier
