IBM Cognos Architecture Overview 

The Cognos architecture explains the fundamental functionalities, types of architecture tires, and working process. Cognos BI is regarded to be a 3-tier architecture layout. A web client or a web server is at the top. A web application server is at the 2nd tier and a data layer is at the bottom tier. 

These three tiers are segregated by varying firewalls and build communication between them. It occurs through protocols like SOAP (simple object access protocol) and HTTP protocols. Let’s get insight into them.

The web application server functions only on Java depending upon the Apache Tomcat server. Through this tier, the Microsoft Excel worksheets will be shifted into web sheets and conduct exporting them to Excel or PDF data formats. 
  • Tier 3 database server: This tier comprises contents and data source management. Tier 3 also includes TM servers and admin servers. LAN connectivity is used to install an admin server on any computer device. This connectivity resides on the same network server.
