IDC公布的2016年中国公有云主流厂商的市场份额来看，阿里云IaaS收入是其他7家供应商的总和。（2016 H1/H2 alicloud's  IaaS revenue is equivalent to the next seven players in china at a 40.7% market share）。

分析认为中国公有云市场增长迅速，来自Gartner的判断认为在2017年中国公有云市场将带来140亿美元收获，2021年将达到250亿美元，年复合增长率达到17.2%。到了2021年中国公有云市场规模可以占据全球市场近6%，这与中国在全球GDP中的位置有关，也与社交媒体、移动技术、电商等蓬勃发展不无关系。

因此，阿里云可以在2016年全球IaaS市场收入中排名在TOP5之列，以5.7亿美金位于第四位。整个全球IaaS收入排名依次为：AWS、Microsoft、IBM、Alibaba、Google。

AWS正主导着公有云市场，尤其是在美国，其他公有云厂商正积极投资追赶，他们似乎也有雄心壮志，包括阿里云在内。Alibaba的马云表示，阿里巴巴将赶上并超越亚马逊。当然当前3.2%的份额与AWS46.1%的份额对比，还是差距很大。

以下是convergedigest网站刊登的《Keeping an eye on Alibaba Cloud, Aliyun》文章精华英文节选：

China’s public cloud market is growing even faster, with Gartner figures showing China’s public cloud market, valued at $14 billion this year, growing to $25 billion in 2021, a 17.2% CAGR; by 2021, China’s share of the global public cloud market would still be under 6%, which seems odd given the country's share of global GDP is much higher and that ecommerce, social media and mobile technologies are booming in China - why so low versus the U.S. market?

Aliyun cited figures from IDC Tracker 2016 H1/H2 Global Cloud Market (IaaS), indicating it currently is the No.4 player in public cloud services worldwide, but with only a 3.2% share; No.1 was AWS, $8.4 billion, 46.1% share; No. 2 Microsoft, $1.4 billion, 7.6% share; No.3 IBM, $1.0 billion, 5.8% share; No.4 Alibaba, $0.57 billion, 3.2% share; No.5 Google, $0.519 billion, 2.9% share.

Clearly, AWS is dominating the public cloud market, especially in the U.S. The other U.S. public cloud players are investing aggressively to catch up and they too seem to have ambitions that reach to the sky. Alibaba's Jack Ma has previously been quoted in the press as saying that Alibaba would catch and surpass Amazon. When it comes to cloud services at least, this will be extremely difficult given its current 3.2% share versus AWS’ 46.1% share, and a capex budget that appears decisively smaller.

In its home market of China, Aliyun's IaaS revenue is equivalent to the next seven players combined. The numbers cited in IDC Tracker 2016 H1/H2 Global Cloud Market are as follows:

No.1 – Alibaba Group, $587 million, 40.7% market share

No.2 - China Telecom, $123 million, 8.5%

No.3 – Tencent, $106 million, 7.3%

No.4 – Kingsoft, $87 million, 6.0%

No.5 – Ucloud, $79 million, 5.5%

No.6 – Microsoft, $72 million, 5.0%

No.7 – China Unicom, $67 million, 4.6%

No.8 – AWS, $55 million, 3.8%

翻译此文意义：

温故知新，

想知道自己能走多远，

那就抬头看一看，

云上大佬一直在前面风雨兼程。
