Hi Nils Gutsche,
Thank you for reaching out to us on the Microsoft Q&A forum.
Microsoft for Startups credits are typically not eligible for purchasing third-party services, such as MinIO, from the Azure Marketplace. This is because third-party services billed directly by their providers are not covered under Azure credits. These credits can only be applied to services billed directly through Microsoft. Most third-party offerings, including MinIO, fall under vendor-billed services and are therefore ineligible. The credits are intended for use with Azure-native services, enabling the development and deployment of solutions on the Azure platform.
Please refer to the following documents: Azure experience for founders, Azure Credits and Billing FAQs
Please reach out to us if you have any other queries.
