Technical Architecture

Installation configurations vary; however, a typical installation is called a single-server installation because the Cherwell Application Server and supporting services are all installed on one machine. A typical single-server installation involves three tiers:

• (Tier 1) Database server: Houses the CSM database (SQL database).
• (Tier 2) Cherwell Server (main server): Houses the Cherwell Application Server and supporting services, and CSM Web Applications.
• (Tier 3) Client machines: House the client-only files/administrator tools (the Desktop Client, CSM Administrator, and all the supporting tools/utilities.

The following figure shows a typical single-server installation.
