According to IDC global spending on public and private cloud infrastructure products (server, storage and ethernet switch) totals $29 billion during 2015, a 21.9% increase over 2014.
Vendor revenues for Q4 2015 total $8.2bn with 15.7% Y-oY growth. The quarter sees cloud infrastructure sales make 32.2% of overall IT infrastructure spending, up from 28% in Q4 2014, with traditional (non-cloud) infrastructure revenues dropping by -2.7% Y-o-Y due to declines across the server, storage and switch segments.
As for the cloud, all three markets show "strong" growth in both private and public segments-- except for public cloud storage, a segment falling by -4% in Q4 2015 on a difficult compare with a very strong Q4 2014. Leading both private and public cloud segments is switches, with respective growth reaching 19.6% and 56.9% Y-o-Y.
"The cloud IT infrastructure market continues to see strong double-digit growth with faster gains coming from public cloud infrastructure demand," IDC says. "End customers are modernising their infrastructures along specific workload, performance, and TCO requirements, with a general tendency to move into 3rd Platform, next-gen technologies. Options on and off premises continue to expand, along with open platforms that enhance hybrid capabilities for a variety of use cases. Public cloud as-a-service offerings also continue to mature and grow in number, allowing customers to increasingly use sophisticated, mixed strategies for their deployment profiles."
On a regional perspective, W. Europe has Q4 2015 cloud infrastructure spending growth of 30.5% Y-o-Y. On the other hand CEE cloud infrastructure spending for the quarter is down by -9.3%, the result of ongoing political and economical turmoil.
