Typical Client Server Architectures

 

 

In a central R/3 System configuration, one host is responsible for all processing tasks

Two?tier R/3 System configurations are usually implemented using special presentation servers that are responsible solely for formatting the graphical interface. Many R/3 System users use PCs with Microsoft Windows ?installed, for example, as presentation servers.

An alternative two?tier configuration is to install powerful desktop systems and to use these for presentation and applications (two?tier client/server). This type of configuration is particularly useful for expensive applications (such as simulations) or for software developers.

In a three?tier configuration, you use your own host for the three tiers. Using data from the database server, several different application servers can operate at the same time. To ensure that the load on individual servers is as even as possible and to achieve optimal performance, you can use special application servers for individual application areas such as sales planning, distribution or financial accounting.

 

To web?enable the SAP Applications, a Web Server and an ITS (Internet Transaction Server) are needed. The web?service and the services for the ITS can run on one server or on two dedicated servers. The presentation in this configuration is provided by an Internet Browser. The new SAP Web platform is NetWeaver.
