"While digital transformation does help to drive the overall market growth, the rapid expansion of datacenter presence from global public clouds services providers at APeJ region does attract enterprises to migrate more workloads to the public cloud environment as that helps to address their concerns in data sovereignty and latency,” says Liew Siew Choon, Senior Market Analyst, IDC Asia/Pacific's Services Research team.
Infrastructure as a Service (IaaS) will be the largest category of public cloud spending in 2018, contributing about 47.60% to the overall cloud spending in the region. This is due to the fast expansion of datacenters by global public cloud service providers, followed by Software as a Service (SaaS), which is very close to the Infrastructure spending on cloud, with a share of 45.83% on the overall spend. IaaS spending will be fairly balanced throughout the forecast with server spending trending slightly ahead of storage spending. PaaS spending will be led by Application Platforms, which will see the fastest spending growth (37.93% CAGR) over the forecast period. Data Management Software, Data Access, Analysis, and Delivery, and Integration and Orchestration Middleware will also see healthy spending levels in 2018 and beyond.

"China and India, the two largest markets in APeJ will account for about 60% of the region's Cloud market size. The Chinese government has been actively promoting the development of the high-tech industry, and continues to implement its Internet+ strategy is a leading factor for China's adoption to cloud technology, for India accelerated demand by enterprises and govt. towards the implementation of new technologies like Blockchain, AI, IoT etc is making the cloud a bare necessity," says Ashutosh Bisht, Research Manager for Customer Insights & Analysis, IDC Asia/Pacific.
The IDC Worldwide Semiannual Public Cloud Services Spending Guide quantifies public cloud computing purchases by cloud type for 20 industries and five company sizes across eight regions and 47 countries. Unlike any other research in the industry, the comprehensive spending guide was designed to help IT decision makers to clearly understand the industry-specific scope and direction of public cloud services spending today and over the next five years.
