+#### Installing on certain Cloud Providers
+
+When installing on certain cloud providers (AWS, Azure) where you are using database as a service, you will not have access to the my.cnf but you can generally use [Database Parameter Groups](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_WorkingWithParamGroups.html) or in [Azure](https://docs.microsoft.com/bs-cyrl-ba/azure/mysql/howto-server-parameters) to set the parameters such as the `log_bin_trust_function_creators` as appropriately. Also with Azure running a DB as a service there needs to be a change made to the installation code as per the answer on [Stack Exchange](https://civicrm.stackexchange.com/questions/31794/civicrm-on-azure-not-finding-the-server). This is due to Azure not permitting connections to databases without credentials.
