With the development of commercial cloud platforms, cloud service technology has become a trend in machinery industry due to lower maintenance costs, easy access, flexible installation, and easy to use. However, currently most of the cloud services provided by international machinery manufacturers only support their own products and are difficult to be integrated with Taiwan's machine networking platforms to provide comprehensive solutions for the industry. This article will take the "Intelligent Cloud Platform for Machinery Industry" launched by several organizations, government, and Taiwan Association of Machinery Industry as an example to introduce how to focus on value-add cloud services based on the intelligent manufacturing and machine networking technology to build the standardized software specification. Through a dedicated cloud app store, this article will discuss in details the mehods and approaches to facilitate integration of different machine networking platforms, to assist the industry to develop digital services and to create customer value.
