I think its important to understand what the key attributes of cloud services are， and how one becomes defined as a cloud service provider. Whats important to know when you think about cloud services is that it has to be service-based； it has to be a service [whether its the provision of software， platform or infrastructure]. It has to be able to be metered， it has to be shared， its got to be scalable and somewhat elastic， and it has to be done through Internet-based technology. Thats how people think about cloud services. Without those attributes， youre really not a cloud service provider.

美國(guó)云計(jì)算服務(wù)供應(yīng)商Equinix CFO Keith Taylor在談到云服務(wù)時(shí)指出，對(duì)于云服務(wù)的認(rèn)識(shí)存在很多誤解。“我認(rèn)為最重要的是理解云服務(wù)的關(guān)鍵屬性，以及如何定義云服務(wù)提供商?！?Taylor強(qiáng)調(diào)，云服務(wù)首先是以服務(wù)為基礎(chǔ)；其自身就是服務(wù)，無(wú)論是軟件、平臺(tái)或基礎(chǔ)設(shè)施。云服務(wù)是可測(cè)量的、能夠共享的、具有可伸縮性，而且一定是依靠互聯(lián)網(wǎng)技術(shù)得以運(yùn)行的?！半x開(kāi)了這些屬性，就不是一個(gè)真正的云服務(wù)提供者?！?/p>
