Scheduler Architecture and Key Features in Distributed Computing

The cluster scheduler is an important component of modern distributed computing infrastructure, and it has evolved significantly in the last few years, so it has got much more attention by the industry and enterprises. With the development of information technology and the increasing demand of distributed applications, the cluster scheduler has been very complex and diversified. Among several resource scheduling system architecture, the design and work mechanism of their scheduler are very different. When we need to change the resource scheduling technology, from the built environment, the basic use, and then to customized modification according to the different business scenarios, each step may take us a lot of effort and cost. Therefore, we need to understand the architecture principles and comprehend their advantages and disadvantages, so as to use the rules and experiences flexibly to optimize our system. This paper first states the classification and meaning of the core performance indicators of scheduling systems, and then summarizes the mainstream scheduler architectures of distributed systems, compares their differences and expounds their characteristics, and then gives a description of the key characteristics of schedulers. In short, it gives a more comprehensive analysis of schedulers.
