作者主页上的信息非常详细.
另外, 作者在CCGrid09上做过一个相关的Keynote:  Market-Oriented Cloud Computing: Vision, Hype, and Reality of Delivering Computing as the 5th Utility

GRIDS Lab & Megha
    这个实验室的项目包括GridBus, GridSim, Aneka等, 人员包括Research Staff和PhD Students各10个左右, 老大就是Rajkumar Buyya. 感觉这个实验室侧重于grid等相关技术与business结合的研究.

Megha: Melbourne Cloud Computing Initiative 
    该实验室云计算研究项目, 有一些有用的资源(论文, 链接).  CloudSim是其中的一个项目,提供云计算建模和模拟的平台.

以下是论文摘录
1. Buyya对云计算的定义
"A Cloud is a type of parallel and distributed system consisting of a collection of inter-connected and virtualised computers that are dynamically provisioned and presented as one or more unified computing resources based on service-level agreements established through negotiation between the service provider and consumers."

    云计算的定义各有各的说法, 大家描述的是一种类似的东西, 但仍然存在差别. Buyya对云的定义比较强调SLA, 但是没有明确提到on-demand以及scalability. Grossman的定义较为简洁(on-demand, Internet, scale, scale and reliability), Foster的定义看起来比较严格, 特别强调了"driven by economies of scale".
    这些都是从"What is cloud computing"的角度来讨论, 对于这种谁都说不清全部的概念, 我觉得还应该从"What is not cloud computing"的角度来理解, 两个圈圈划出来, 在小圈里的都是云计算, 在大圈外的都不是云计算, 两个圈圈之间的就是暧昧发生的地方, 新手因为纠结于"是与否"而感到迷茫与痛苦, 老手却能早早就在尽情享受了.

2. High-level market-oriented cloud architecture (S2)
作者从商业的角度来阐述云架构, 强调的是要根据SLA来提供服务. 本节里面只是描述了一下这个系统, 不涉及技术细节的(全文也不涉及技术细节).

3. Global CLoud Exchange and Markets (S4)
    作者描绘了一个云服务的市场, 与以前其他人论文里提到的Web Service的market类似, 参与的角色无非就是consumer, provider, broker, 还要有发现, 选择, 协商等机制. 现在看起来, 很浮云.   要想形成一个活跃的市场, 可替换服务的选择要比较多才行, 目前cloud service/provider的数量还没有达到这种程度, 而且不同cloud provider提供的服务portability/interoperability比较差, 导致用户的转移成本太高, 不利于形成一个有效地市场.

P.S
今天发现了一个国内云计算门户网站(chinacloud.cn), 由解放军理工大学教授刘鹏教授创办, 资源挺丰富的, 推荐了很多相关论文(可下载), 相关会议信息的收集等, 感觉不错, 继续关注.
