The global public cloud services market grew by 28.6 per cent year on year in the first half of 2017, bringing in revenue of $63.2 billion (£48.2 billion), according to International Data Corporation (IDC) Worldwide Semiannual Public Cloud Services Tracker.

Among the three primary segments of public cloud services – Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) – the SaaS segment, which makes up 68.7 per cent of the overall market share, was the slowest growing segment, recording a 22.9 per cent year-on-year rise.

The segment that saw the strongest growth was PaaS, increasing by 50.2 per cent year on year, despite only comprising 13.6 per cent of the public cloud services market. Larry Carvalho, IDC’s worldwide Cloud Platform and Developer Services research manager, said the “rapid adoption of container technology in the PaaS segment has given developers additional tools to accelerate application development and deployment”.

Meanwhile, the IaaS segment represented 17.8 per cent of the public cloud services market in the first half of 2017, and continues to show strong year-on-year growth, at 38.1 per cent. Amazon Web Services leads this segment in market share and growth.

In addition, IDC said that the last three years have seen a resurgence of focus on public cloud IaaS by major technology companies, including Microsoft, Google and Huawei.

Frank Gens, IDC senior vice-president and chief analyst, said: “Public cloud adoption is accelerating in large part as enterprises recognise that the cloud has become the launchpad for virtually every new IT innovation in the last 24 months – including AI, blockchain, quantum computing and more.”

He went on to say that organisations “not on the public cloud will be increasingly isolated from the world of tech innovation”.
