yii2 global variables?

Question

Yii

I am working on a project on yii2 (video portal). It is planned to use 3 servers, 1 main and 2 for static (photo, video...). Question: how and in what place can I set a variable in yii2 responsible for the ip addresses of static servers? It would be nice to write the addresses in config/params.php, but how do you get the values ​​from there?

Yii::$app->params[ '...' ];
