Azure Classroom Series – 06/Aug/2020

Azure VM Concepts

  • By default, azure vms are created in a multi-tenant mode (Same physical server will have different vm’s from different accounts) Preview
  • Azure Operates multiple data centers around the world. These are grouped into geographical regions.
  • Special Azure Regions
    • US Gov Virginia and Us Gov lowa
    • China East & China North: partnership b/w Microsoft & 21Vianet.
    • Germany Central & Germany Northeast: Customer data remains in Germany under control of T-Systems.

Virtual Machine Types

  • Types of Virtual Machines in Azure are
    • General Purpose
    • Compute Optimized
    • Memory Optimized
    • Storage Optimized
    • GPU
    • High Performance Compute
  • In Azure VM when we create vm instance we get to select CPU,RAM combination & hard disk counts
  • General Purpose Compute:
    • Provide Balanced CPU-to-memory ratio.
    • Ideal for dev & test, small to medium databases and low to medium traffic web servers.
  • Compute Optimized:
    • These VM sizes have high CPU-to-memory ratio
    • Ideal for medium traffic web servers, network appliances, batch processes and application servers.
  • Memory Optimized:
    • These VM sizes have high memory-to-cpu ration.
    • Ideal for relational databases, medium to large cache service & in-memory analytics
  • Storage Optimized:
    • These VM sizes offer high disk throughput & IO
    • Ideal for Big Data, SQL, NOSQL databases, Data warehousing.
  • GPU optimized Virtual machines:
    • The VM sizes are specialized vm with GPUs (Single, multiple & fractional)
    • Ideal for compute-intensive, graphics-intensive and visualization workloads
  • High Performance Compute:
    • HPC optimized VM Sizes are used to solve some of the most computationally intensive problems like fluid dynamics, earth modeling, weather simulations etc.
