Moving a change to other servers
Features in D8 is the way to sync features across multiple sites. And was the default in D7 to import and export database changes. Which in D8 is solved by Configuration management.

Please read the docs (thoroughly): Managing your site's configuration.

You routinely have to drush cex after you've made changes via the UI. This will export database values into multiple (hundreds/thousands) *.yml files. Then your colleagues will have to drush cim after they pulled the latest *.yml files to get the changes imported into their DB.
