Azure Storage

Blob / Table / Queue

Storage Account

Name

Access Key

Max. 500 TB / storage account

Table Storage

Non-relational storage

Schema-free (max 255 columns)

Max. row size 1MB

Very slow filtering, ordering & search

Very fast access by primary key

Scalable

Partition Key, Row Key, Timestamp

Blob Storage

Containers

Access Levels

Shared Access Signature

Blob Types

Block Blob

4 MB blocks, max. 50000 blocks

Page Blob

512 B blocks, max 1TB

Optimized for read/write access

Storage Types

Standard Storage

Premium Storage

Better performance

Optimized for virtual machines

Queue Storage

Multiple writers, multiple readers

Order of messages not guaranteed (if you need, use Service Bus)

Enqueue waiting Dequeue process message Delete

If not processed within specified timeout (default 30), the message is

enqueued again

Use DequeueCount property to get rid of poisoned messages

Virtual Machines & Resource Manager

Supports both Windows and Linux

Resource Manager Deployment

JSON template

Deployment via PowerShell, Azure CLI or REST API

Application Insights

Advanced Application Monitoring

Trace Events & Exceptions with custom metadata

Server Performance, Page Load Times, App Availability...

Correlation ID & Search Events by User

Azure Functions

Micro-service Architecture

Uses C# Script language (.csx files)

#ref directives to load packages and assemblies

Connectors for input and output

Blob / Queue storage

Service Bus

HTTP request

Webhook

Docker Basics

Dockerfile

A script used to build a single container

Docker-compose

Compose several containers and deploy them together

docker run

docker-compose up

Azure Container Service

Hosting and Orchestration of Containers

Docker Swarm

Cubernetes

DC/OS

Master – manages the farm of agents

Agents – hosts containers

Load balancer – seting up port forwarding and health probes

Connect using SSH to Master

tunneling of port 2375 to localhost:23750

Set DOCKER_HOST environment variable to localhost:23750

Use Docker CLI commands to work with containers

Azure Machine Learning

Algorithms

Classification: Is this A or B (or C)?

Regression: How Much?

Clustering: How it is organized?

Anomaly Detection: Is this weird?

Reinforcement Learning: What should I do next?
