The invention provides a high-
concurrency service scene
processing method and
system and a storage medium. The
system comprises a
current limiting subsystem, a cache inventory query subsystem, a real inventory query subsystem, an order subsystem, a
payment subsystem and a real inventory
processing subsystem. Comprising the following steps: reasonably dividing a high-
concurrency service according to a
service process; dividing the whole
business process into a plurality of subsystems, where each subsystem independently completes own business; and after the
self service is completed, calling a subsystem of a
service process, so that the whole
service process is completed. Each subsystem is small in service
processing amount, short in
response time and high in processing speed, the
concurrency amount of an instantaneous high-concurrency service scene is increased through cooperative operation of the subsystems, and the user experience is good. Moreover, the subsystems are relatively independent, the
fault tolerance of the
system is improved, when one subsystem is changed, the use of other subsystems is not affected, and the system is applied to different scenes and is high in flexibility and applicability.
