Aspects of the present disclosure are directed toward a distributed computing system in which host computing devices host computing services that are only accessible by client computing devices and other computing services associated with a particular computing channel for a line-of-business and in which host computing devices host computing services that are accessible by client computing devices and other computing services across lines of business. The computing services are configured according to a common application interface (API) that provides a modular configuration allowing the computing services to be deployed across multiple computing channels for multiple lines-of-business respectively. Aspects of the present disclosure are also directed toward an automated deployment system that is configured to automatically deploy computing services at a computing platform based on a computing platform template and one or more computing service templates.
