$44bn of cloud hardware in 2017, IDC

According to the IDC report, total spending on IT infrastructure products—including server, enterprise storage and Ethernet switches—for use in cloud environments will grow a healthy 18 percent this year [2017] to top $44 billion. Meanwhile, IDC said, investment in old-school non-cloud architecture equipment will actually decline by more than 3 percent in 2017.

Public vs. private:


Some 61 percent of cloud infrastructure spending is going into public cloud data centers, while off-premise private cloud environments will garner just under 15 percent of total cloud spending.
