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)
- 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.

Virtual Machine Sizes
- With Virtual Machine Size, we select
- vCPUS: number of virtual cpu’s
- RAM : memory in GiB
- Data Disks: Number of disks that can be connected
- Max IOPS: speed of the disk io
- Temp Storage
- Premium disk: Is SSD Supported
- On a broader note , with VM size we select
- CPU
- RAM
- DISK
