At that time, blue flood used hardware-specific physical devices such as 3DNS, Cacheflow, Netcache, Array networks, and so on. If the customer needs CDN acceleration requirements, operators need to log on to a variety of servers to manually carry out the corresponding configuration maintenance, both error-prone and inefficient.
