Chinese companies enlarged investment on cloud security as cloud computing has become prevalent in the country, industry experts said on Thursday.

To meet the increasing demand, PwC (PricewaterhouseCoopers) and the Cloud Security Alliance (CSA) signed a strategic cooperation agreement in Shenzhen.

The CSA, established in 2008 in the US, is a non-profit organization to formulate industry standard and provide qualification recognition for above 400 members around the world, such as Amazon, Microsoft, Huawei Technologies and Google.

The two parties will work together on cloud security’s standard formulation, talent training and qualification recognition in China market.

Yale Li, Chairman of CSA Greater China region and also the chief security scientist of Huawei, said he was positive about the future of cloud security in China.

"Cloud computing is already prevalent in China and the country will lead the development of cloud security in the world in a few years,"he said.

Yale added while business only took off in past two years in the country, the gap between China and the US has been shrinking as major technology companies, such as Alibaba, Tencent and Huawei, amplify their investment in this area quickly.

Aliyun, Alibaba's cloud computing subsidiary, has realized a three-digit-growth of sales, he said.

Lisa Li, PwC China cybersecurity and privacy partner, said 45 percent of IT system of companies in Chinese mainland and Hong Kong are operating under cloud technology.
