Basics of Azure cloud services.

Azure

Learning azure as cloud services.

Common terminologies

• Fault domain - Rack, common power source
• Update domain - group of connected hardware that can undergo update, maintaineance at the same time.
• Availability set - collection of fault domain and update domain in the same zone.
• Availability zone - deploy identical VM into separate availability zones which separates the fault domain and update domain.
• ARM - JSON template that can be used to create resources.
• Virtual Machine scale set - the scale set is to group vm into one image. it can be loaded up or loaded down. Use load balancer before the scale set.

Common Concepts

• Networking in Azure & Cloud in General. Sheet
• Data/databases in Azure Sheet
• Messaging in Azire Sheet

Make sure the VM are spread across Fault domain and Update domain.

AZ Resources.

name	What it does
VM	Virtual Machines
App Services	Hosting web apps
ACR (Cart Docker)	Cart for hosting docker images
AKS (Kubernetes services)	Azure k8 services.
Azure Functions	Serverless solution to deploy solutions that dont rely on cloud infrastructure and solutions.
Logic Apps	Workflow that integrates with apps
ACI	Docker without k8.
App Service Container	Deploy docker to app service
App Service Enviornment ASE	Complete isolation of VMs on Vnet & Subnets.
Load Balancer	balances load between Vms. Good for internal resources.
Application Gateway	To manage web apps just as same as Load Balancer. Good for external resources..
WAF Web Firewall WAF	Protection against common web app threats.
