### **Understanding Azure Cosmos DB and MongoDB**

🌟 **Azure Cosmos DB** is a globally distributed, multi-model database service offered by Microsoft Azure. It provides scalability, high availability, and low-latency access to your data.

🐘 **MongoDB** is a widely used open-source NoSQL database that stores data in JSON-like documents. It's known for its flexibility and ease of use.

### **Step 1: Create an Azure Cosmos DB Account**

1. **Sign in to Azure Portal**: Go to [https://portal.azure.com](https://portal.azure.com) and sign in with your Azure account.

2. **Create a New Cosmos DB Account**: Click on "+ Create a resource," then search for "Azure Cosmos DB." Select it from the results and click "Create."

3. **Configure the Cosmos DB Account**:
   - Choose a unique ID for your account.
   - Select the API for MongoDB.
   - Choose a subscription and resource group.
   - Select a preferred region, or enable global distribution.
   - Configure networking and security settings as needed.

4. **Create the Account**: Click "Review + Create" and then "Create" to create your Cosmos DB account.

### **Step 2: Access Your Cosmos DB Account**

1. Once your account is created, navigate to it in the Azure portal.

2. In the left-hand menu, click on "Data Explorer" to access your Cosmos DB account.
