Azure VM Types

• Azure has categorized VM Sizes by the Type. The Types of the Virtual machine sizes are
  • General Purpose:
    • Balanced CPU-memory ratio
  • Compute Optimized
    • High CPU-memory ratio
  • Memory Optimized
    • High memory-cpu ratio
  • Storage Optimized:
    • High disk throughput
  • GPU:
    • Targeted for heavy graphics rendering, video editing, Model Training and deep learning
  • High Performance Compute (HPC):
    • fastest and most powerful CPU virutal machines
• Every VM Type has some sizes associated with them
  
• Each Letter like B/D/E etc in the VM Size refers to a Hardware specification
  • Refer Here for one such specification
• When the VM Size contains a letter s this means premium disks are supported
• Exercise:
  • Try to find the hardware Technology for Mv2 and M
  • Try to find the Hardware technology for F and FX
  • Once you find the Technology try to google about that hardware.
