Cosmos DB overview and use cases in Azure - Mini Project: Build & Apply

Cosmos DB Overview and Use Cases

📖 Scenario: You are working as a cloud architect for a company that wants to store and access data globally with low latency. They want to understand how Azure Cosmos DB can help them achieve this goal.

🎯 Goal: Build a simple Azure Cosmos DB setup with a database and container, and configure it for global distribution to demonstrate its use cases.

📋 What You'll Learn

Create an Azure Cosmos DB account with Core (SQL) API

Create a database named RetailDB

Create a container named Products with partition key /category

Configure the Cosmos DB account for multi-region write to enable global distribution

💡 Why This Matters

🌍 Real World

Companies use Cosmos DB to build applications that need fast, global access to data, such as retail websites, gaming platforms, and IoT solutions.

💼 Career

Cloud architects and developers use Cosmos DB to design scalable, globally distributed databases that meet performance and availability requirements.

1

Create Cosmos DB account with Core (SQL) API

Create an Azure Cosmos DB account named myRetailAccount using the Core (SQL) API.

Azure

# Create Cosmos DB account named myRetailAccount with Core (SQL) API
# Your code here

Need a hint?

Use the Azure CLI command az cosmosdb create with the --kind GlobalDocumentDB option for Core (SQL) API.

2

Create database RetailDB

Create a database named RetailDB in the Cosmos DB account myRetailAccount.

Azure

az cosmosdb create --name myRetailAccount --resource-group myResourceGroup --kind GlobalDocumentDB
# Create database RetailDB
# Your code here

Need a hint?

Use az cosmosdb sql database create with the account name and database name.

3

Create container Products with partition key /category

Create a container named Products inside the database RetailDB with partition key /category.

Azure

az cosmosdb create --name myRetailAccount --resource-group myResourceGroup --kind GlobalDocumentDB
az cosmosdb sql database create --account-name myRetailAccount --resource-group myResourceGroup --name RetailDB
# Create container Products with partition key /category
# Your code here

Need a hint?

Use az cosmosdb sql container create with the database name, container name, and partition key path.

4

Enable multi-region write for global distribution

Configure the Cosmos DB account myRetailAccount to enable multi-region write to allow global distribution.

Azure

az cosmosdb create --name myRetailAccount --resource-group myResourceGroup --kind GlobalDocumentDB
az cosmosdb sql database create --account-name myRetailAccount --resource-group myResourceGroup --name RetailDB
az cosmosdb sql container create --account-name myRetailAccount --resource-group myResourceGroup --database-name RetailDB --name Products --partition-key-path "/category"
# Enable multi-region write on myRetailAccount
# Your code here

Need a hint?

Use az cosmosdb update with the --enable-multiple-write-locations true flag to enable multi-region writes.
