The invention provides a front service platform of a bank. The platform comprises a channel access subsystem for integrating transactions when various clients of a channel layer access each service system of a background processing layer in the bank, a service processing subsystem for integrating functions provided by a background service system and thus realizing novel bank services, an application switching subsystem serving as a channel for the front service platform to access each service system on the background, a monitoring management subsystem for monitoring the operating condition of the front service platform, and a safety control subsystem for ensuring safe operation of the front service platform. The invention has the advantages of providing a unified platform capable of supporting the development of various front services, making the whole service system of the bank simple and reliable, greatly reducing equipment cost, and laying a solid foundation for the extension of service products of the bank.
