7. "Serverless Kubernetes and architecture scene analysis"
Container and non-server is the current hot topic of cloud native, the combination of the two greatly reduced the threshold for the use of the container, reducing the total cost of computing, but also allows users to get rid of the complexity of the underlying infrastructure management. However, a large-scale and high flexibility Serverless Container infrastructure is not an easy thing, to consider the size, flexibility, cost, efficiency and other factors. This article shall explain in detail to these questions.
8. "Kubernetes vertical automatic retractable go from here?"
Currently Kubernetes Pod level of auto-scaling (HPA, Horizontal Pod Autoscaler) has been widely used in the industry. But for some special Pod (such as some state Pod), HPA and can not solve the problem of insufficient resources. This leads to a vertical automatic retractable Pod (VPA, Vertical Pod Autoscaler), this paper describes Kubernetes community development planning Pod automatic vertical telescoping assembly.
