They also need to adjust the number of running service based on traffic and have clear division of labor in system development and management. Additionally, they are billed based on usage. These requirements have led to the emergence of the Serverless concept. Currently, there have been many performance tests conducted on Serverless in public clouds, but there is still limited research on private clouds. Therefore, this paper uses the normal open source Serverless frameworks, including Knative, OpenFaaS, Nuclio and Fission, to deploy on a Kubernetes private cloud platform, in order to compare the differences between the resource usage utilization and execution performance for different Serverless frameworks. The main task of this research is to test the resource usage status of Serverless framework and understand which frameworks are more lightweight. Furthermore, when the number of service replicas scaled to zero, the cold starts can be occurred can result in the executing service deploy. Therefore, the effect of cold starts on execution performance is verified by periodically connecting from the client to the service, and the performance of different Serverless frameworks in executing functions synchronously and asynchronously is compared. Finally, this paper explains which Serverless frameworks are suitable for different usage scenarios as the research result. en_US DC.subject 負載平衡 zh_TW DC.subject 故障轉移 zh_TW DC.subject Serverless zh_TW DC.subject Kubernetes zh_TW DC.subject Knative zh_TW DC.subject OpenFaaS zh_TW DC.subject Nuclio zh_TW DC.subject Fission zh_TW DC.subject load balance en_US DC.subject fault tolerance en_US DC.subject Serverless en_US DC.subject Kubernetes en_US DC.subject Knative en_US DC.subject OpenFaaS en_US DC.subject Nuclio en_US DC.subject Fission en_US DC.title 基於 Kubernetes 做開源 serverless compute platform 效能測試 zh_TW dc.language.iso zh-TW zh-TW DC.title Performance Evaluations of Open Source Serverless Compute Platforms based on Kubernetes en_US DC.type 博碩士論文 zh_TW DC.type thesis en_US DC.publisher National Central University en_US
