Virtualization of resources in cloud computing has enabled developers to commission and recommission resources at will and on demand. This virtualization is a coin with two sides. On one hand, the flexibility in managing virtual resources has enabled developers to efficiently manage their costs; they can easily remove unnecessary resources or add resources temporarily when the demand increases. On the other hand, the volatility of such environment and the velocity with which changes can occur may have a greater impact on the economic position of a stakeholder and the business balance of the overall ecosystem. In this work, we recognise the business ecosystem of cloud computing as an economy of scale and explore the effect of this fact on decisions concerning scaling the infrastructure of web applications to account for fluctuations in demand. The goal is to reveal and formalize opportunities for economically optimal scaling that takes into account not only the cost of infrastructure but also the revenue from service delivery and eventually the profit of the service provider. The end product is a scaling mechanism that makes decisions based on both performance and economic criteria and takes adaptive actions to optimize both performance and profitability for the system.

从 DevOps 到 BizOps

云计算中的资源虚拟化使开发人员能够根据需要随意委托和重新委托资源。这种虚拟化是一枚有两面的硬币。一方面，管理虚拟资源的灵活性使开发人员能够有效地管理成本；当需求增加时，他们可以轻松移除不必要的资源或临时添加资源。另一方面，这种环境的波动性和变化发生的速度可能对利益相关者的经济地位和整个生态系统的业务平衡产生更大的影响。在这项工作中，我们将云计算的商业生态系统视为一种规模经济，并探讨这一事实对有关扩展 Web 应用程序基础架构以解决需求波动的决策的影响。目标是揭示和正式确定经济上最佳扩展的机会，不仅要考虑基础设施的成本，还要考虑服务交付的收入以及最终服务提供商的利润。最终产品是一种扩展机制，它根据性能和经济标准做出决策，并采取自适应措施来优化系统的性能和盈利能力。
