Azure Cosmos DB Serverless Capacity in Public Preview
Traditionally, Cosmos DB required the user to provision a certain amount of Request Units (RU). Under this model, a minimum amount of RU’s would not be required. This follows the same consumption model as Azure Functions.
This is now in preview and while I’d like to make this a little longer, this is a welcomed feature that will hopefully hit General Availability soon. Being able to pay-as-you-go is always one of the benefits of the cloud, considering there aren’t any monetary discounts, other than not having to meet a minimum commitment to use the service.
