4. 3 L4 Switch Bank N (1/2) The internet banking system of Bank N is built using WebtoB, JEUS, and its core banking system uses Tmax, TmaxSoft’s middleware solution, which has proven performance and reliability for transaction processing. 10 Cache Servers 10 WebtoB Servers 6 JEUS Servers2 JEUS Servers Client To optimize the performance of the internet banking system, cache servers are implemented separately. 1. System State Composed of four personal internet banking servers, two business internet banking servers, and ten web servers. Cache servers which handle static content and WebtoB are composed as a ratio of 1:1. (When cache servers are used, the overall CPU usage rate can be reduced by approximately 20%. * Reference : Currently 38 web servers and 14 WAS are operated.

9. 8 WEB + WASTrading Server WMP Investment & Securities Company W (1/2) Investment & securities company W runs its website system by communicating between a WMP server and a trading server through WebtoB, JEUS, and a WMP gateway. WebtoB + JEUS are installed as an integrated server. (Web server + Server for the presentation logic) Since the trading server runs on TP-monitor, a gateway needs to be used to connect the web application server and the TP monitor. 1. System State WebtoB and JEUS are installed on fifteen web servers. Five servers are configured as one group. Each JEUS server is configured as one container. This enables a centralized session server. Fifteen containers use the primary session server. WebtoB and JEUS are installed on fifteen web servers. Five servers are configured as one group.
