摘要
The present disclosure provides a method and a device of storage capacity evaluation based on a CDN application. The method includes: for any cache server corresponding to a target service, using files stored before a preset time node as old files in the cache server; determining a proportion of the old files in all files stored by the cache server and a visiting rate of the old files within a preset visit time range; determining an adjustment type of a storage capacity of the cache server according to the proportion of the old files and the visiting rate of the old files, where the adjustment type at least includes capacity to-be-expanded, capacity to-be-reduced and capacity unchanged; and determining an adjustment type of a storage capacity of the target service according to adjustment types of storage capacities of all cache servers corresponding to the target service. The disclosure simultaneously considers storage cost and bandwidth cost and may also evaluate different services.
