If the “neural network” of the information system is paralyzed, it will be fatal. In view of the actual needs of Internet applications such as rapid development, massive users, large amounts of data, and low latency, the functional structure and system architecture are decomposed to make each functional service modular, and the system architecture presents high cohesion and low coupling, which is convenient for flexible response to frequent updates and upgrades of e-commerce: support cross-border cloud deployment, elastic expansion, and meet performance requirements such as high concurrency and high availability. Ensure the stability of power supply and network, equip the field/station/warehouse with generators to prevent power outages; prepare local mobile phone network cards to prevent network disconnection, install signal enhancement equipment, improve and optimize dual-line channels, and strengthen the protection of cross-border dedicated VPN routing from China. Computers, printers, scanners and other hardware must be spared to prevent equipment from continuous operation fatigue or burnout; set up order templates, do a good job of printing debugging, and PC inspection to ensure smooth operation. New systems, new processes, and new equipment should be tested and run in advance, and strategy verification and stress test drills should be conducted on the system and supporting hardware, and functional changes should be frozen. Estimate the amount of data, expand performance and balance the load in advance, clean up redundant data, travel light, prepare system emergency plans, and make off-site backups of cross-border systems.
On the day of the peak season, logistics enters the ultimate open mode, which is the highlight of fulfilling orders and shipping. Although there are IT personnel to maintain the system hardware and software and arrange technical personnel to support on-site, various accidents will still occur every time there is a big promotion order explosion, such as abnormalities in on-site operation, network, interface communication or data synchronization. System security must be linked between the front and back ends, synchronized with production scheduling, real-time monitoring of data, and mastering system performance, host status and network traffic; if the order structure is far from the forecast, timely adjustments should be made. Many hidden problems are hard to prevent and need to be flexible. For example, when reviewing or shipping packages, the barcode recognition of the gun still has an error rate of about 0.1%. Because many people are online at the same time, the system will be stuck, delayed, or have a small probability of downtime interrupting operations. Consider whether it is necessary to switch to pure manual mode to keep the operation uninterrupted. Today’s logistics operation system is highly dependent on computers. Except for a few links such as handling, loading and unloading, and sorting, which can be operated manually, most operations must wait until the system is restored, otherwise the shipment can only be delayed or the operation can be suspended. Computers can also temporarily provide necessary auxiliary support for operations and customer service, such as data query, modification, import and export, and statistical analysis.
