Cloud IT infrastructure spending — server, disk storage, and ethernet switch — will grow 21 percent to $32 billion in 2015.
IDC said Cloud IT infrastructure spending will be accounting for approximately 33 percent of all IT infrastructure spending against about 28 percent in 2014. Private cloud IT infrastructure spending will grow by 16 percent to $12 billion, while public cloud IT infrastructure spending will grow by 25 percent in 2015 to $21 billion.
In 2014, cloud IT infrastructure spending rose 18.7 percent to $26.4 billion; private cloud spending grew 20.7 percent to $10 billion, while public cloud spending increased 17.5 percent to $16.5 billion, said IDC.
In 2015, Western Europe is expected to have the highest growth in cloud IT infrastructure spending at 32 percent, followed by Latin America (23 percent), Japan (22 percent), and the US (21 percent).
cloud IT infrastructure spending will grow at a compound annual growth rate (CAGR) of 14 percent; both public cloud and private cloud are expected to grow at the same CAGR.
By 2019, cloud IT infrastructure spending to be $52 billion, or 45 percent of total IT infrastructure spend; public cloud will represent about $32 billion of that amount, and private cloud will account for the remaining $20 billion.
Kuba Stolarski, research manager, Server, Virtualization and Workload Research at IDC, said: “As the market evolves into deploying 3rd Platform solutions and developing next-gen software, organizations of all types and sizes will discover that traditional approaches to IT management will increasingly fall short of the simplicity, flexibility, and extensibility requirements that form the core of cloud solutions.”
