Greeting!
As I understand, you are experiencing issues while creating an Azure Cosmos DB account and have queries related to its cost.
Please find the below standard procedures and support plans:
- Database region not supported: Some regions may not be available for Azure Cosmos DB due to subscription type, availability zone limitations, or other restrictions. If you're using a free or Pay-As-You-Go subscription, certain regions might not be listed.
- Pricing for learning purposes: Azure Cosmos DB offers different pricing models, including serverless and provisioned throughput options. If you're just experimenting, you might want to use the Azure Cosmos DB free tier, which provides 1000 RU/s and 25 GB of storage at no cost for the lifetime of the account. This is a great way to explore Cosmos DB without incurring charges. I kindly request you to please share the details requested in the private message for further investigation, which will help us address the issue. If required, we will create a support request for your issue.
