 # Azure-CosmosDB
 
+1. An Azure Cosmos DB API for MongoDB is created in the Azure Portal and Capacity is chosen as Provisioned Throughput.
+1. A fresh mongo dump is taken and restored to Azure CosmosDB account using a Python Script.
+1. After the dump is successfully restored, the database and collections can be seen  in the Data Explorer Panel as follows: 
+<img src="https://gitlab-pm.knowledgelens.com/abhinandan.joshi/azure-cosmosdb/-/raw/master/images/img9.jpg"/>
+
+Based on the above data, a few observations are made:
+1. After 12 hours of creating an account and restoring the Mongo Dump, **12 USD** was charged.
+1. After more than 24 hours, **33 USD** was charged.
+1. After  28-30 hours, **15 USD** was charged.
+1. After 48 hours, **25 USD** was charged.
+
+Totally around 85 USD has been charged. And then, the database was removed and the account was kept as it is.
+
+The following screenshots can be used to get an idea of the **Throughput and estimated costs** by the databases:

+
+**Inference** : It can be inferred that the total throughput(in Request Units/second) is **48,400**.
+
+**Reason for Total Throughput Value**: 
+There are two methods of provisioning throughput while creating the Azure Cosmos DB Account -  
+* [ ] Collection Level
+* [ ] Database Level 
+

+
+If not specified explicitly, then *Collection level will be chosen by default*.
+As specified in the above figure, minimum 400 RU/s per collection. So totally 12 Collections. 12*400 = 4800 RU.
+
+The following screenshots of **Activity Log** can be used to get an idea of the different activities that were triggered in the CosmosDB Account:
+

+**Screenshot 2**

+
+The above screenshots were taken before the databases were deleted in the CosmosDB account. 
+
+**Screenshot 3** : This screenshot was taken after DBs were removed from the Account.

+
+The reason for which the amount was charged can be concluded as follows :
+According to the screenshots from Activity Log, there are few operations which get triggered in a certain intervals of time, which perform one of the following Operations : Read,Insert, Upsert, Delete and Query. 
+The RU will be charged for these activities as follows:
