We have a large customer base that encompasses most of China’s Internet users. Currently, the number of concurrent online accounts has exceeded 100 million. However, network conditions are different in different places of China leading to an interconnection bottleneck. In order to support our business development and improve user experience, we have been very cautious in selecting datacenters. We would assess the quality of a datacenter from many different aspects including network quality, cost, service, and historical operation performance. Our decision to choose 21Vianet as our service provider was made after comprehensive comparison, based on the added value that the company could provide for us.

Wu Di, VP Business, Network Platform BU at QQ.com

As China’s largest dating website, we have put great importance on the users’ experience in visiting our website. The network information exchange among users is different from other Internet sectors, and the nationwide distribution of our users requires our datacenter to cover users from different networks across the country. By choosing 21Vianet’s datacenters, we have satisfactorily solved this issue. 21 Vianet’s services, which have been customized based on our business needs, has led to very good results.

Zhang Dawei, CTO at Jiayuan.com

The information exchange between our SNS users is frequent. Interactions among users of our website produces a massive amount of data. This is different from client end online games, and the data traffic of users generally shows substantial fluctuations. When it comes to selecting a datacenter, we would need a service provider capable of customizing their services to accommodate our data needs. 21Vianet has a huge datacenter network, and can provide customized solutions and swift responses based on our business requirements. They have provided convenient and fast services for us, and have effectively supported our business.

The video industry is an industry where “being fast” is very important. Website’s speed should be fast, video play should be smooth and fast, and the speed of loading videos should also be fast. As a leading company in the industry, YOUKU believes that “speed is the king”. We have spent hundreds of millions of RMB in developing our nationwide network, in order to improve user experience and continuously increase the smoothness of video play as well as the speed of loading videos. During this process, our decision to use 21Vianet has played a critical role. 21Vianet has been our datacenter service provider for quite a while. Its nationwide datacenter service has provided effective support for our “fast” strategy.

We have a huge number of YY voice users in various parts of China. We provide high-quality voice service for them in real time. In order to let users better enjoy our voice service, our datacenter need to be as close to the end users as possible, to achieve the best coverage. Meanwhile, we need to deploy core applications in our datacenters located in tier-1 cities. 21Vianet’s nationwide distribution and multi-layer datacenter meets our requirement. By deploying core applications in datacenters located in tier-1 cities such as Beijing, Shanghai and Guangzhou as well as deploying datacenters in tier-2 & 3 cities to get closer to end users, we have overcome a major barrier to further business growth. 21Vianet has proved a strong business partner for our company.

Zhang Tao, O&M Director at DUOWAN.Com

As provider of MMO games, in order enhance the gamers’s gaming experience, we must maintain very high requirements for the quality of our datacenters, bandwidth stability and transmission rate, which are all very important factors to us. 21Vianet’s datacenters are very good, especially its BGP product, which we have been using for a long time. We put our core apps in 21Vianet’s datacenters, which are stable and fast. Our proven success collaborating with 21Vianet gives us peace of mind while using their datacenters.
