4.2. Reflection Checkpoint: Storage Solutions

Take a moment to reflect on your mastery of Azure storage services. Use these prompts to self-assess and reinforce your ability to choose and implement the right solution:

Scenario: You've just completed developing solutions that use various Azure storage services. You need to consolidate your understanding of their distinct roles and how they interoperate to build robust data solutions.

💡 Think of it like a filing system: You've learned different cabinet types (Blob, Cosmos, Queue, Table). The mastery isn't knowing each drawer—it's knowing instantly which cabinet to open when someone hands you a document.

⚠️ What breaks without storage synthesis? Choosing wrong storage early is expensive to fix. Migrating from Table Storage to Cosmos DB mid-project can delay launches by months. Get it right upfront.

Reflection Question: How do Azure's diverse storage services (Storage Accounts, Blobs, Files, Backup), with their various configuration options (redundancy, tiers, lifecycle, soft delete), collectively interconnect to address diverse storage and protection needs, balancing cost, performance, and resilience?

Self-Assessment Prompts:

• What is the difference between LRS, ZRS, and GRS redundancy, and when would you choose each?
• When would you use Azure Files instead of Azure Blob Storage?
• How do Blob Versioning and Soft Delete work together to protect data?
• What is the primary purpose of a Recovery Services Vault?
