  • Virtual Machine size defines

    • number of vCPUs
    • size of RAM
    • number of data disks
    • temporary disk size
  • Virtual Machine Types: Refer Here

    • General Purpose:
      • Balanced CPU-Memory Ratio
    • Compute Optimized:
      • High CPU to Memory Ratio
    • Memory Optimized
      • High Memory to CPU Ratio
    • Storage Optimized:
      • These tyepes provide high disk througput
    • GPU:
      • Targeted for heavy graphics rendering, video editing and machine learning model trainging & deep learning
    • High Performance Compute
      • Fast & Most Powerfull CPU Virtual machines
  • VM Series: Each VM Series is designed for specific vm type with diffent hardware configuration. Each Series is represented by an alphabet and they have versions (Generations). Any VM Series with S in it supports SSD Harddisk

  • For Free Tier, we can use

    • A Windows VM For 750 hours/month of vm size B1s
    • A linux VM For 750 hours/month of vm size B1s
  • Virtual Machine Pricing: Generally for any VM

    • Price is based on vm size
    • Price is impacted by Operating System (Windows machine will have extra price due to OS license)
    • Disks are not included in VM Pricing (Only temp disk is part of vm)
    • VM Prices may differ slightly from one region to other region
    • Pricing model for vm
      • On-demand
      • Reserved Instances
      • Spot VMS
  • Lets create a Windows Virtual Machine of Type Memory Optimized Preview Preview

  • Lets create a Linux Virtual Machine which is General purpose and has 4 VCPU’s and atleast 8 GB of RAM Preview

  • Once the vm is created can i change type?

    • Yes, But the machine will be restarted (So, there will be downtime) Preview Preview Preview
