Skills Learned

  • Skills Learned
    • Describe products available for Compute such as
      • Virtual Machines,
      • Virtual Machine Scale Sets,
      • App Services,
      • Functions,
      • Azure Container Instances (ACI) and
      • Azure Kubernetes Service (AKS)

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
