It provides HA function only with ESB without a separate HA solution. 

HTTP, JMS, Web Service, REST, FILE, FTP, TCP, Custom adapter, etc. 

All files can be linked regardless of file size by using a large-capacity dedicated processing engine.

Built-in system remote control, intelligent error tracking, and real-time message tracking systems enable quick response in case of failure.

Compatible with all systems that support standard protocols. (If the standard protocol is not supported, an interworking function is provided using a separate relay adapter.) 

Batch deployment and update capabilities are provided by the center without visiting the institution in person. Automatic daily updates from remote agents to ensure you always have the latest version. 

As a core technology to realize SOA by combining various next-generation IT technologies, it is an infrastructure solution for service integration using service combination, message conversion, intelligent routing, and protocol conversion. 

It consists of the following components: 

 1) EAI : an adapter in charge of sending and receiving 

 2) MCMgr : which controls/manages/stores all related data 

 3) Integrator : which maps logic and data for data 

 4) EMC : A management console that controls/manages/monitors all EAI processes

 5) IStudio : a development tool that allows easier and faster customization of MESIM EAI products​ 

It is a middleware that efficiently integrates data and processes by organically connecting a large number of distributed applications. It is a solution that integrates and operates the system stably using the Hub & Spoke method. 

MESIM EAI is a Java-based solution. Therefore, JDK must be installed by default, and DBMS is required for product setting, transmission/reception history, and data management. In addition, if additional functions such as redundancy are to be built, L4, CFS (Cluster File System) equipment is required.
