New data from Synergy Research Group shows that the total number of large data centers operated by hyperscale providers increased to 504 at the end of the third quarter, having tripled since the beginning of 2013. The EMEA and Asia-Pac regions continue to have the highest growth rates, though the US still accounts for almost 40% of the major cloud and internet data center sites. The next most popular locations are China, Japan, the UK, Germany and Australia, which collectively account for another 32% of the total. Over the last four quarters new data centers were opened in 15 different countries with the US, Hong Kong, Switzerland and China having the largest number of additions. Among the hyperscale operators, Amazon and Microsoft opened the most new data centers in the last twelve months, accounting for over half of the total, with Google and Alibaba being the next most active companies. Synergy research indicates that over 70% of all hyperscale data centers are located in facilities that are leased from data center operators or are owned by partners of the hyperscale operators.
