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.
Logical Partition Size
Second big change is about the Logical Partitions, Logical Partition size used to be 10 GB, Cosmos DB team changed the limit to
20 GB. This can be a good or bad news depends if you pick the right partition id. It is good because you can store more data in the same partition, all data can reside in one partition if you have smaller application. If you have a large application, you will have bigger distribution. Also, this can be bad news if you pick the wrong partition id for your collection. It might take longer for you to understand you pick the wrong partition. Partitioning is important in Cosmos DB and It is one of the big reasons for your solution to be success or fail.
Multi-Master Promo
There is also a promo going on if you need a Multi-Master database. You can get discount price up to
%33 off for new accounts enabling multi-region writes. All you need to do is, create a new account with multi-region option enabled and you might save up to
%33!
Number of Collections limit for Shared Database Throughput
There is another news about shared database throughput, Cosmos DB team limited the number of collections to
25 per database. This should allow for better throughput sharing all the collections if you have shared database throughput.
