标题： Carbon-Aware Microservice Deployment for Optimal User Experience on a Budget

摘要： 数据中心的碳足迹最近已成为一个关键问题。 到目前为止，大多数碳感知策略都集中在通过调整工作负载执行的时间和位置，利用批处理调度决策的灵活性。 然而，由于服务导向的云应用程序必须在任何时间点都能被访问，并且通常需要低延迟，因此这些方法无法应用于服务导向的云应用程序。 我们提出了一种在每小时碳预算下运行微服务的碳感知方法。 通过为每个微服务选择最合适版本和水平扩展，我们的策略在遵守预算限制的同时最大化用户体验和收入。 在各种应用配置和碳预算上的实验表明，该方法能够正确适应变化的工作负载和碳强度。 显示英文摘要

摘要： The carbon footprint of data centers has recently become a critical concern. So far, most carbon-aware strategies have focused on leveraging the flexibility of scheduling decisions for batch processing by shifting the time and location of workload executions. However, such approaches cannot be applied to service-oriented cloud applications, since they have to be reachable at every point in time and often at low latencies. We propose a carbon-aware approach for operating microservices under hourly carbon budgets. By choosing the most appropriate version and horizontal scaleout for each microservice, our strategy maximizes user experience and revenue while staying within budget constraints. Experiments across various application configurations and carbon budgets demonstrate that the approach adapts properly to changing workloads and carbon intensities.
