At the beginning of the establishment of Xiamen Meiyou Co., Ltd. in 2013, the industry's cloud ecosystem was not perfect. Therefore, the original architecture of Meiyou used the traditional development method of self-built computer rooms. So far, the number of servers in the managed machine room has reached 300; at the same time, in order to meet the trend of big data development, Meiyou also built its own Hadoop, Spark , Storm, Kylin and other corresponding big data processing platforms; in terms of databases, mainstream databases such as MySQL, MogoDB, Redis, CounchBase, etc. are used. In 2014, after contacting Alibaba Cloud, Alibaba Cloud products were gradually adopted, from the initial exposure to the public beta ADS (Advanced Design System) to the currently used cloud server, MaxCompute, cloud database, analytical database, TAE, Alibaba Cloud Shield, etc. At present, Meiyou has formed a hybrid cloud model, which not only has a certain size of hosting room, but also actively uses Alibaba Cloud products.
