Key Terms & Fundamental Concepts

Question 1

Azure Storage Overview

4 Types

3 Access Tiers

4 Redundancy Options

2 Performance Tiers

Answer 1

non-relational data store

Types of Storage

1. Blob: file share but for all type of unstructured data
2. File: file share/similar to share drive
3. Queues: messages
4. Tables: structured non-relational data

​Acccess Tiers

1. Hot: low cost/high perf. retrieval, high cost storage
2. Cool: high cost/low perf. retrieval, low cost storage
3. Archieved: highest cost/lowest perf. retrieval, lowest cost storage

Redundancy:

1. Local: within a datacenter
2. Zone: across availability zones, within region
3. Geo: within single avilability zone, across region
4. Go-Zone: across availability zones, across region

Performance:

1. Standard: more storage and redundancy options but perf. will not be as fast
2. Premium: designed for high perf., quick access to data but with limited storage and redundancy options

Question 2

Run & Train Models: Control Script

Answer 2

Control script: allow you to run a script on different compute resources. Controls how and where your machine learning code is run.
