Total cloud IT infrastructure spending (server, disk storage, and ethernet switch) will grow by 21 percent year over year to $32 billion in 2015, accounting for approximately 33 percent of all IT infrastructure spending, which will be up from about 28 percent in 2014.
According to latest IDC findings, private cloud IT infrastructure spending will grow by 16 percent year over year to $12 billion, while public cloud IT infrastructure spending will grow by 25 percent in 2015 to $21 billion.
For the full year 2014, cloud IT infrastructure spending totalled $26.4 billion, up 18.7 percent year over year from $22.3 billion; private cloud spending was just under $10.0 billion, up 20.7 percent year over year, while public cloud spending was $16.5 billion, up 17.5 percent year over year.
For the five-year forecast period, IDC expects that 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, IDC expects 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.
“The pace of adoption of cloud-based platforms will not abate for quite some time, resulting in cloud IT infrastructure expansion continuing to outpace the growth of the overall IT infrastructure market for the foreseeable future,” says Kuba Stolarski, Research Manager, Server, Virtualisation and Workload Research, IDC.
“As the market evolves into deploying 3rd Platform solutions and developing next-gen software, organisations 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.”
