The application tier is made up of three main server components: An IBM Cognos BI server also renders the Cognos Connection interface. An IBM Cognos BI server runs requests, such as reports, analyses, and queries, that are forwarded by a gateway. The Application Tier contains one or more IBM Cognos BI servers. For failover protection, you can configure more than one dispatcher for a gateway computer. If you install the gateway component on a different computer from Content Manager or Application Tier components, you must configure the gateway computer so that it knows the location of a dispatcher, preferably one on an Application Tier components computer. Web communication can also occur directly with an IBM Cognos BI Dispatcher, although this option is less common than using gateways. A gateway is an extension of a web server program that transfers information from the web server to another server. Web communication in IBM Cognos Business Intelligence is typically through gateways, which reside on one or more web server. High availability or scalability requirements can be met with multiple redundant gateways being deployed along with an external HTTP load-balancing router. The IBM Cognos Gateway manages all web communication for the IBM Cognos platform. The Web Tier facilitates user connections to IBM Cognos BI applications, and the component that fulfills this role is called the IBM Cognos Gateway. The tiers are based on business function and are typically separated by network firewalls. These server roles define the tier within the architecture that an IBM Cognos BI server uses. Within the IBM Cognos platform, servers are normally grouped together to fulfill certain roles within a distributed deployment. IBM Cognos is a web-based service-oriented architecture (SOA) made up of three server tiers: For more detailed information, see the IBM Cognos Business Intelligence Architecture and Deployment Guide. The following is a high-level overview of the IBM Cognos Business Intelligence architecture. This is an archive related to a previous version of Esri Maps for IBM Cognos.
