According to the International Data Corporation (IDC) Worldwide Quarterly Cloud IT Infrastructure Tracker, vendor revenue from sales of infrastructure products (server, storage, and Ethernet switch) for cloud IT, including public and private cloud, grew 25.8% year over year in the second quarter of 2017 (2Q17), reaching USD 12.3 billion, the company said.
Public Cloud infrastructure revenue grew 34.1% year over year and now represents 33.5% of total worldwide IT infrastructure spending at USD 8.7 billion, up from a 27.0% share one year ago.
Private Cloud revenue reached USD 3.7 billion for an annual increase of 9.9%. Total worldwide cloud IT infrastructure revenue has almost tripled in the last four years, while the traditional (non-cloud) IT infrastructure revenue continues to decline and is down 3.8% from a year ago, although it still represents 52.4% of the worldwide share of overall IT revenue at USD 13.6 billion for the quarter.
Public Cloud now represents 70.2% of the total cloud IT infrastructure revenue. The market with the highest growth in the public cloud infrastructure space was Enterprise Storage Systems with revenue up 30.4% compared to the same quarter of the previous year, and making up over a third of the revenue in public cloud.
Server and Ethernet Switch public cloud IT infrastructure revenues were up 24.6% and 26.8% respectively. Private cloud infrastructure spending continues to be driven by the server market, which has remained nearly 60% of the revenue in that space for the past 18 quarters.
