About this chapter
What this chapter covers
This chapter covers data that does not fit neatly into relational tables: files, blobs, key and attribute entities, and documents. Azure offers Azure Storage for the first three and Azure Cosmos DB for flexible, globally distributed databases.
The exam asks you to match a described need to the right service, so the aim is to remember what each one is best at.
How the topics fit together
The pages move from simple, cheap storage to a full database service.
- Azure Blob Storage covers blob types, access tiers, redundancy and lifecycle rules.
- Azure Files and Table Storage covers managed file shares and the key and attribute store.
- Azure Cosmos DB covers request units, partitioning, consistency, global distribution and the APIs.
When a question names a storage need, look for the data shape first. Unstructured objects point to Blob Storage, a shared drive points to Azure Files, simple key lookups point to Table Storage, and a flexible, scalable database points to Cosmos DB.
How to use these pages
Each topic page has the same shape, so you can skim for what you need.
- What it is: the idea in plain words.
- How it works: the mechanism, with examples and tables.
- What to remember for the exam: the facts to memorise and how questions are phrased.
- Common mistakes: the classic traps.
- Check yourself: three questions to test your understanding.
