SERVER CAPACITY EXPANSION METHOD AND CAPACITY EXPANSION SYSTEM

摘要

Embodiments of the present application provide a server capacity expansion method and a capacity expansion system. According to an embodiment, embedding in advance a virtual cloud host mirror in a first sub-database of a physical machine, and embedding a service container mirror in a second sub-database; when a virtual server needs capacity expansion, directly using the embedded virtual cloud host mirror to build a cloud host container, and loading the configuration file of a target service container mirror to the configuration directory of the cloud host container so as to complete the building of the virtual cloud server. The whole building process does not involve pulling files from a mirror library at a cloud end, but instead uses a virtual cloud host mirror and a service container mirror embedded locally to build a virtual server. During server capacity expansion, the process can prevent network congestion caused by a large number of physical machines making requests to a mirror repository, thereby conserving virtual server build time and achieving rapid capacity expansion.
