beijing shiji information technology (002153.SZ) stated in investor relations that the cloudization of hotel information systems is fundamentally due to the development of mobile phones and the penghua csi mobile internet index fund(lof)-a, which requires consumers on the C end to access hotel information systems. The old generation systems cannot support direct access by C-end consumers because they are completely offline and their architecture does not support such access. After the hotel information system is cloudified, fundamentally, it can provide intelligent data support for hotel operators' decision-making. Cloud systems can improve the management efficiency of hotel groups and save labor costs for hotels. However, a very important driving factor is data security. With the strict enforcement of data security laws and regulations in various countries, the old non-cloud systems cannot meet the requirements of these data security laws and regulations. For example, after the implementation of the personal data protection law in the country, hotels need to undergo data security certification every year. If it is a non-cloud system, it means that every hotel has to pay a relatively high fee for data security certification every year; but if it goes to the cloud, it means that all hotels in at least a particular region only need to be certified once. Therefore, as countries increasingly strengthen control over data security, going to the cloud directly assists hotels. Currently, the cloudization of hotel information systems is already an industry consensus.
