Web Hosting is used to store and host website content, and operates similarly to virtual servers. An ECS instance is divided into multiple spaces that can be of various sizes. A space corresponds to an account, and indicates a Web Hosting instance. Each space has an independent FTP and web access permission, but all spaces share the hardware resources of the ECS instance.
Web Hosting is commonly sold in resource packages that contain server computing resources, memory, network transmission traffic volume, and management tools.
