Techniques for metadata-driven dynamic content serving. Metadata content is stored as a source instance. The metadata content is utilized to provide dynamically-constructed pages. The metadata content is published to runtime pods communicatively coupled to receive the metadata content. The source instance includes a metadata definition repository and is a primary source of dynamic data for serving pages in the runtime pods. The runtime pods are groups of multiple servers that act as a single entity to dynamically generate metadata-driven content in response to requests received from client devices. A request for content is received with a selected one of the runtime pods for a specific site. The specific site is mapped to a user identified by a user identifier. The user identifier is utilized to retrieve site metadata from a site metadata server. Content is provided in response to the request with the selected runtime pod utilizing the metadata content.
