SDKs vs REST APIs

Software Development Kits

Language specific libraries
Better for large applications that require a specific language
Simplify authentication and requests

REST Application Programming Interface

Uses standard HTTP calls
Great for quick scripts, integrations, or lightweight devices

Multi use tool

3 ways to authenticate

Connection strings.
- Best for local dev.
Shared Access Signature

Why CRUD matters

Developers often need to store, retrieve, and modify data.
Azure SDKs and REST APIs handle these tasks securely and efficiently.
Cipher Coffee examples:
- Store order receipts as blobs.
- Retrieve promotional images for the website.
- Remove expired marketing files using lifecycle policies.

Best practices

Batch operations to minimize network calls.
Use async methods for throughput.
Retry on transient failures (HTTP 429 or 503).
Log x-ms-request-id for debugging.
