Why? prices of OVH are very similar to Hezner one, both have phisical server ecc

OVH and Open Telekom Cloud have the vast majority of the features that you request and are provider EU based and owned. IMHO: - Configuration management, not needed, i vastly prefer Ansible. If you mean IAC: terraform is the best. - Domain and cert registration. Domain use 3dparty - Email /SMS: use third party provider
