Virtualization

• Emulation of physical machines
• Different virtual hardware configuration per machine/app
• Different operating systems per machine/app
• Total separation of environments
  • file systems,
  • services,
  • ports,
  • middleware,
  • configuration

Virtual Machines

• Infrastructure as a Service (IaaS)
• Total control over the operating system and the software
• Supports marketplace and custom images
• Best suited for
  • Custom software requiring custom system configuration
  • Lift-and-shift scenarios
• Can run any application/scenario
  • web apps & web services,
  • databases,
  • desktop applications,
  • jumpboxes,
  • gateways, etc.

Virtual Machine Scale Sets

• Infrastructure as a Service (IaaS)
• Set of identical virtual machines
• Built-in auto scaling features
• Designed for manual and auto-scaled workloads like web services,* batch processing, etc.

Containers

• Use host’s operating system
• Emulate operating system (VMs emulate hardware)
• Lightweight (no O/S)
  • Development Effort
  • Maintenance
  • Compute & storage requirements
• Respond quicker to demand changes
• Designed for almost any scenario

Azure Container Instances

• Simplest and fastest way to run a container in Azure
• Platform as a Service
• Serverless Containers
• Designed for
  • Small and simple web apps/services
  • Background jobs
  • Scheduled scripts

Azure Kubernetes Service (AKS)

• Open-source container orchestration platform
• Platform as a Service
• Highly scalable and customizable
• Designed for high scale container deployments (anything really!)

App Service

• Designed as enterprise grade web application service
• Platform as a Service
• Supports multiple programming languages and containers

Azure Functions (Function Apps)

• Platform as a Service
• Serverless
• Two hosting/pricing models
  • Consumption-based plan
  • Dedicated plan
• Designed for micro/nano-services

Summary

• Virtual Machines (IaaS) - Custom software, custom requirements, very specialized, high degree of control
• VM Scale Sets (IaaS) - Auto-scaled workloads for VMs
• Container Instances (PaaS) - Simple container hosting, easy to start
• Kubernetes Service (PaaS) - Highly scalable and customizable * container hosting platform
• App Services (PaaS) - Web applications, a lot of enterprise web * hosting features, easy to start
• Functions (PaaS) (Function as a Service) (Serverless) - micro/nano-services, excellent consumption-based pricing, easy to start
