Kubernetes for Cloud-Native Computing: A Comprehensive Analysis of Scalability, Security, and Performance Challenges

Containerization and microservices are the core concepts that enabled cloud- native computing as a new way of delivering applications. Kubernetes is an open-source tool that can be considered as a platform for container orchestration and it is widely used currently. In this paper, a summary of scalability, security and performance concerns of Kubernetes are discussed in detail. The strength and limitation of Kubernetes are explored based on studies, and theoretical and experimental work is done in the large-scale cloud environment. This paper identifies several priorities and weighs potential solutions if Kubernetes is to be used in large scale contexts. It is also worthwhile to provide an experimental analysis of Kubernetes scaling and performance increase in focused scenarios. Possible directions and further improvements are also considered and proposed for future studies as well as the security improvement concerns
