The randomness of public health events requires that the cloud-native architecture, as the mainstream architecture of the new generation of the public health information system, has the appropriate flexibility to meet the needs of environmental change. The flexible acquisition of cloud-native architecture requires organizations to invest additional resources. How to plan and formulate resource input is a topic of common concern for public health management and information systems. According to the commercial characteristics of the public health system based on cloud-native architecture, this paper systematically analyzes the external major impact factors and auxiliary factors that affect the flexible cost investment strategy of cloud providers and combines flexible investment strategies to build a cloud-native cost investment model. Finally, case data in practice is applied into the model, and cost planning is discussed according to different situations. The findings indicate that (1) the more cloud providers adopt the changed flexible strategy, the more conducive it is to reduce costs; (2) the larger the application load, the more cloud providers need to use flexible strategies to lower costs; (3) the less the impact of changing the flexible strategy on costs, the more conducive cloud providers use the flexible strategy to decrease costs; (4) the more uneven the distribution of diversity, the higher proportion of investment increases than the proportion of investment, and the more cloud providers consider the investment using flexible strategy. The results of the discussion provide a reference for public health organizations to use flexible strategies and change flexible strategies in a timely manner and expand the research scope of information system cost investment.

公共卫生信息系统云原生架构的灵活投资策略

公共卫生事件的随机性要求云原生架构作为新一代公共卫生信息系统的主流架构，具有适当的灵活性来满足环境变化的需求。灵活获取云原生架构需要组织投入更多资源。如何计划和制定资源投入是公共卫生管理和信息系统普遍关注的话题。根据基于云原生架构的公共卫生系统的商业特点，系统地分析了影响云提供商柔性成本投资策略的外部主要影响因素和辅助因素，并结合柔性投资策略构建云原生平台。成本投资模型。最后，在实践中将案例数据应用到模型中，并根据不同情况讨论成本计划。调查结果表明：（1）云提供商采用更改后的灵活策略的企业越多，降低成本的优势就越大；（2）应用程序负载越大，更多的云提供商需要使用灵活的策略来降低成本；（3）更改弹性策略对成本的影响越小，更有利于云提供商使用弹性策略降低成本；（4）多样性的分布越不均匀，投资增加的比例就比投资的比例高，并且更多的云提供商使用灵活策略来考虑投资。
