Hasan Savran hits on a few changes to Cosmos DB:
Free Tier of Cosmos DB
Couple of big changes came from Azure Cosmos Db team this week. First one is, free tier of Cosmos DB. In free tier, you get the first 400 Request Units and 5 GB of storage for free for the lifetime of the account. This is a great deal if you like to use Azure Cosmos DB in your new project. Give it a try, It’s free! All you need to do is click on Apply for Apply Free Tier Discount.
This is a big one, but there are a few other interesting changes in there as well.
