Study Notes

Microsoft Azure Cosmos DB - Module 02 Study Notes

Non-relational data services in Azure: Azure supports various non-relational services like Azure File Storage, Blob Storage, Data Lake Store, and Cosmos DB. Each serves different data types (e.g., Cosmos DB for documents, Blob Storage for binary objects).
Provisioning non-relational data services: Provisioning is creating and configuring a service. This involves setting up resources (disks, memory, CPU, network).
Provisioning process overview:
- User specifies parameters (storage, memory, compute power).
- Azure allocates resources.
- Service is ready for use.
Provisioning tools:
- Azure portal: User-friendly interface for most users. It has dedicated pages with prompts.
- Azure CLI: Command-line interface (CLI) for automation. Can be used on various OS (Windows, macOS, Linux). Allows storing and running scripts.
- PowerShell: Used by administrators for scripting and automation.
Scaling: Adjusting service resources (size of storage, memory) after the service is set up. This is important if initial estimates of workload are incorrect.
Example scenario (Contoso): Contoso (manufacturing) requires various non-relational stores for different data types (real-time production line status, quality control, etc) to improve efficiency.
