According to new findings from Synergy Research Group, such investment was driven by “burgeoning demand” for public cloud services, alongside a need for “ever-richer” server configurations, which drove up enterprise server average selling prices (ASPs).
Specifically, spending on public cloud infrastructure grew by 30%, while spending on enterprise data center infrastructure grew by 13%.
The latter was driven by 23% growth in private cloud or cloud-enabled infrastructure, which helped to offset a "marginal decline" in traditional, non-cloud infrastructure, according to findings.
"Cloud service revenues continue to grow by almost 50% per year,” said John Dinsdale, chief analyst at Synergy Research Group. “Enterprise software-as-a-service [SaaS] revenues are growing by 30%, search/social networking revenues are growing by almost 25% and e-commerce revenues are growing by over 30%.
“All of which are helping to drive big increases in spending on public cloud infrastructure.”
In terms of market share, Dinsdale said ODMs in aggregate account for the largest portion of the public cloud market, with Dell EMC ahead of Cisco, HPE and Huawei.
Furthermore, the 2018 market leader in private cloud was Dell EMC, followed by Microsoft, HPE and Cisco - Dinsdale said the same four vendors led in the non-cloud data center market, though with a different ranking.
Delving deeper, Dinsdale said total data center infrastructure equipment revenues, including both cloud and non-cloud, hardware and software, were US$150 billion in 2018, with public cloud infrastructure accounting for "well over" a third of the total.
“Private cloud or cloud-enabled infrastructure accounted for a little over a third of the total,” Dinsdale added.
Meanwhile, servers, operating systems (OS), storage, networking and visualization software combined accounted for 96% of the data center infrastructure market, with the balance comprising network security and management software.
By segment, Dell EMC is the leader in both server and storage revenues, while Cisco is dominant in the networking segment.
“Microsoft features heavily in the rankings due to its position in server OS and visualization applications,” Dinsdale explained.
Outside of the leading pack followed HPE, VMware, IBM, Huawei, Lenovo, Inspur and NetApp, with Inspur and Huawei achieving the strongest growth during the past 12 months.
“We are also now seeing some reasonably strong growth in enterprise data center infrastructure spending, with the main catalysts being more complex workloads, hybrid cloud requirements, increased server functionality and higher component costs,” Dinsdale added.
“We are not seeing much unit volume growth in enterprise, but vendors are benefiting from substantially higher ASPs.”
