Frequently asked questions
What does IONOS do?
IONOS is european web hosting, cloud and domain services — a german alternative to godaddy and aws. It is listed under cloud infrastructure and hosting on EU Alts because its core functionality serves teams looking for a European cloud infrastructure tool with EU data residency, typically as a switch away from AWS.
Is IONOS GDPR compliant?
IONOS is headquartered in Montabaur, Germany and falls under EU jurisdiction, so it likely processes user data under the GDPR by default. Customer data processing is supervised by Germany's data protection authority, the Bundesbeauftragte für den Datenschutz und die Informationsfreiheit (BfDI). EU Alts has not independently verified IONOS's exposure to the US CLOUD Act, so we can't confirm it either way.
How do teams switch from AWS to IONOS?
Teams considering a move from AWS to IONOS are usually drawn by its cloud infrastructure workflow fit. EU Alts has not independently verified IONOS's exposure to the US CLOUD Act, so treat any CLOUD Act or Schrems II conclusions as provisional. Plan a migration in stages regardless: export your data from the US incumbent, pilot IONOS with a small team, then move the rest once integration coverage is confirmed.
