Front-facing machine

Recently, a new project, because there is a bank to deal with the place, so the use of the bank provided by the front of the machine, online check some of the front-mounted computer information.

The concept of front-mounted machine is generally used in banks, brokers, telecommunications operators, more. These places have a lot of background core processing system, external to provide a variety of interface services. If I have some kind of business interface that needs to deal with their backend systems, it's absolutely not allowed to access their backend systems from our external network. At this time, they ask you or they to develop a software, run in their intranet, and then through a dedicated line or hardware isolation technology will run this software to connect the computer to your external network system, then the computer running this software, from the function called the front-mounted machine.

Pre-machine action: From the network and security point of view, it has the role of the isolation of the host (a place outside the intranet, separate intranet applications) to ensure that external applications can not directly access the core services, such as the bank's various external interfaces (telecommunications generation fees, silver card pass).

From a business perspective, the front-facing machine provides a bridge between the business channel and the host of the core service. It generally plays a role in managing and dispatching transactions initiated by the business channel, which can alleviate the burden of the core backend server by the call of the front-end machine, of course, it also has non-core business processing function.

is located in the application system server side and the client's independent processor system, responsible for data format conversion, connection management, business flow Management peripheral scheduling, peripheral processing, and the business data into the background application service system processing tasks.

C and S are relatively relative, although most are fixed, but also depending on the designation. For example, in a bank's business application, the issue of the request cannot be from the backend application server. In the case of proxy charges, the front-facing machine is an application gateway. In fact, in today's application, the host becomes invisible due to the presence of a front-facing machine.
