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.
