Load sharing and three-layer disaster tolerant system suitable for catering industry

Abstract

The invention discloses a load sharing and three-layer disaster tolerant system suitable for the catering industry. The load sharing and three-layer disaster tolerant system comprises a central server, a plurality of transaction servers, a plurality of customer terminals and a plurality of handheld shop terminals, wherein the central server and the transaction servers can achieve real-time data transmission, the handheld shop terminals are connected with the transaction servers or the central server, the handheld shop terminals are preferably connected with the transaction servers, the customer terminals are connected with the transaction servers or the central server, and the customer terminals are preferably connected with the transaction servers. Due to the facts that the customer terminals can respectively have access to the transaction servers and the central server and the transaction servers and the central server can achieve real-time data transmission, the purposes of sharing transaction load, carrying out fault disaster tolerance and promoting development of the catering industry are achieved.

Description

technical field [0001] The invention relates to the field of catering, in particular to a load sharing and three-layer disaster recovery system suitable for the catering industry. Background technique [0002] A disaster recovery system refers to the establishment of two or more systems with the same functions. When one system stops working unexpectedly, the entire application system can be switched to another, so that the system functions can continue to work normally. With the development and promotion of smart devices such as smart phones, they have also been fully applied in the catering industry. In the traditional catering industry, it is necessary to ensure the normal operation of the background server at all times. Since the current catering industry does not have a good disaster recovery system, once the background server is damaged, it is easy to cause consumers to be unable to eat normally, and such failures require staff to It is time-consuming to check each lin...

Problems solved by technology

In the traditional catering industry, it is necessary to ensure the normal operation of the background server at all times. Since the current catering industry does not have a good disaster recovery system, once the background server is damaged, it is easy to cause consumers to be unable to eat normally, and such failures require staff to It is time-consuming to check each link, and it may even cause the catering industry to fail to operate normally, bringing a lot of inconvenience to catering owners and consumers

At the same time, in the catering industry at the present stage, customers generally directly access the main server, which has higher requirements on the entire server. With the increase of customers and stores, it will cause a great burden on the main server. Computing performance will decrease accordingly
