This IDC study is the Japan storage services market into professional services, which consist of the three categories of consulting, integration, and management services; and support services, which maintain products. A market forecast for 2017–2021 is provided based on revenue performance in 2016 and on market trends."To undertake digital transformation (DX) in companies, it is necessary to have innovative changes that will increase the flexibility, scalability, and economic efficiency of IT infrastructure. In particular, as the use of Internet of things (IoT) and cognitive and artificial intelligence (AI) systems will support the increase in data volume efficiently, the need to reconstruct new storage infrastructure, including cloud, will increase. The revenue weight of the storage services business will gradually shift from routine services such as integration services and support services to high value-added consulting services for operational issues and storage infrastructure design," says Yasusuke Suzuki, research manager, Enterprise Infrastructure, IDC Japan.
