The core technology of Tik Tok is the AI ​​recommendation engine. The AI ​​recommendation engine is a system that can recommend information based on the user's rating or preference settings on a certain content.

Take the video platform as an example. In order to make accurate recommendations, the recommendation engine needs data on the type, synopsis, actors and directors of the movie, the user's viewing history, and all the data of a large user base with similar viewing habits as the user. It also needs to consider comments, messages on social platforms, and even what language is displayed on the screen.

With such a huge amount of data, a large amount of memory and storage is required to handle these workloads.
