WordPress is executed with [PHP FPM](https://www.php.net/manual/en/install.fpm.php) and CKAN with [uWSGI](https://uwsgi-docs.readthedocs.io/en/latest/). Additional to these, the service has multiple databases: WordPress requires MySQL and CKAN requires PostgreSQL with additionally required Redis-database and Solr search index.
