dc.description.abstractCloud computing and software containers have seen major adoption over the last decade. Due to this, several container orchestration platforms were developed, with Kubernetes gaining a majority of the market share. Applications running on Kubernetes are often developed according to the microservice architecture. This means that applications are split into loosely coupled services that are distributed across many servers. The distributed nature of this architecture poses significant challenges for the observability of application performance. We investigate how such a cloud-native application can be monitored and dimensioned to ensure smooth operation. Specifically, we demonstrate this work based on the concrete example of an enterprise-grade application in the telecommunications context. Finally, we explore autoscaling for performance and cost optimization in Kubernetes i.e., automatically adjusting the amount of allocated resources based on the application load. Our results show that the elasticity obtained through autoscaling improves performance and reduces costs compared to static dimensioning. Moreover, we perform a survey of research proposals for novel Kubernetes autoscalers. The evaluation of these autoscalers shows that there is a significant gap between the available research and usage in the industry. We propose a modular autoscaling component for Kubernetes to bridge this gap.en
