Microsoft Office 365 and Windows Azure Come to China

Partnering With Shanghai Municipal Government and 21Vianet to Offer Microsoft
Office 365 and Windows Azure Services Throughout China

SHANGHAI, China, Nov. 1, 2012 (GLOBE NEWSWIRE) -- Microsoft Corporation
(Nasdaq:MSFT) ("Microsoft"), 21Vianet Group, Inc. (Nasdaq:VNET) ("21Vianet")
and the Shanghai Municipal Government, announced today that they have signed a
strategic partnership agreement to expand Microsoft's premier commercial cloud
services—Office 365 and Windows Azure—into China. Mr. Baojun Ai, Member of the
Standing Committee of the CPC Shanghai Municipal Committee, deputy mayor of
Shanghai; Mr. Ralph Haupter, Corporate Vice President, Chairman and CEO of
Microsoft Greater China Region, and Mr. Josh Chen, Chairman and CEO of
21Vianet attended the signing ceremony to celebrate the milestone.

Mr. Josh Chen, Chairman and CEO of 21Vianet stated: "We are proud to partner
with a world technology leader and become the Chinese provider for Office 365
and Windows Azure services in China. We believe that this commercial cloud
platform will bring Chinese enterprises unprecedented operational efficiency
and flexibility. By leveraging Microsoft's strong brand reputation and over 15
years of cloud experience, as well as 21Vianet's data center expertise, we aim
to build one of China's premier cloud computing platforms."

In China, this new partnership will meet the requirements of customers by
delivering Office 365 in two ways:

  oServices operated by 21Vianet in China. 21Vianet will operate and offer
    Office 365 and Windows Azure services in China. In addition, Microsoft has
    signed a memorandum with the municipality of Shanghai, where 21Vianet is
    locating a major datacenter for these services. This option will provide a
    consistent Office 365 experience while meeting the demands of customers
    who prefer to use online services provided by a local company that stores
    their data within China. These services will be subject to Chinese laws.
  oServices operated by Microsoft. For Chinese customers who prefer to use
    services managed and delivered by Microsoft itself, Microsoft will provide
    Office 365 from Microsoft datacenters in Singapore and Hong Kong. These
    services will be subject to the laws of Singapore or Hong Kong.

There is strong demand for secure, reliable and scalable public cloud services
in China -- a recent Forrester Research report on cloud computing (Forrester
Research, Sizing The Cloud Markets In Asia Pacific, Feb. 3, 2012) found that
Chinese organizations are beginning to mobilize around the cloud. "The public
cloud market in China will grow from $297 million in 2011 to $3.8 billion in
2020. The three segments of the virtual private cloud market will grow from
$44 million in 2011 to $1.6 billion in 2020. The unparalleled economic growth
in China will certainly help spur strong cloud market growth in China across
most cloud segments through 2020." Microsoft and 21Vianet are excited to bring
our commercial cloud services to market in China and serve the productivity
needs of local businesses.
