一种云计算操作系统TransOS:基于透明计算的设计与实现

摘要

Cloud computing has become a hot topic recently. Among many research issues of cloud computing,CCOS (cloud computing operating system) has attracted extensive attention. However,to date,there is no answer to such related issues:What is a cloud computing operating system? Why we need it? How to develop a CCOS? And no successful instance of CCOS has been witnessed. In this paper, we introduce a CCOS from the viewpoint of transparent computing,i.e.,a customer-controlled cloud computing, in which the client machines serve users' computing and services, and the networked servers provide the storage of programs and data. The CCOS manages all the networked and virualized hardware and software to provide a unified service for users. Traditional operating systems,such as Linux and Wimdows are also defined as resources in the CCOS,which runs between the traditional operating system and the BIOS of computer motherboard. Therefore,the CCOS is a super operating system (Meta OS), which manages a variety of networked resources,including traditional operating systems. This paper first introduces the concept of transparent computing and the Meta OS based on transparent computing, and then gives the layered structure of Meta OS and one of its implementation examples.%云计算正成为计算机研究和应用的热点.在云计算研究的许多问题中,云计算操作系统的研究受到了广泛重视.但是,至今为止,人们对什么是云计算操作系统?怎样研制云计算操作系统?以及为什么要有云计算操作系统等问题并没有给出答案,也没有看到成功的云计算操作系统实例.本文从透明计算,也就是用户控制的云计算(Customer Controlled Cloud Computing)角度出发,以用户端提供用户服务、网络服务器提供程序和数据的存储、对网络软硬件资源进行管理来定义云计算操作系统.我们把传统操作系统,例如Linux、Windows等也定义为资源.把云计算操作系统定义为运行在传统操作系统与计算机主板BIOS之间,对包含各种传统操作系统在内的网络资源进行管理的超级操作系统(Meta OS).本文首先介绍什么是透明计算和基于透明计算的云计算操作系统,然后给出该系统的结构和相关实现实例.
