Question: Virtual Machine Types

This family includes the M1 and M3 VM types.
These types provide a balance of CPU, memory, and network resources, which makes them a good choice for many applications.
The VM types in this family range in size from one virtual CPU with two GB of RAM to eight virtual CPUs with 30 GB of RAM.
The balance of resources makes them ideal for running small and mid-size databases, more memory- hungry data processing tasks, caching fleets, and backend servers.
M1 types offer smaller instance sizes with moderate CPU performance.
M3 types offer larger number of virtual CPUs that provide higher performance.
It is recommended to use M3 instances if you need general-purpose instances with demanding CPU requirements.

This family includes the C1 and CC2 instance types, and is geared towards applications that benefit from high compute power.
Compute-optimized VM types have a higher ratio of virtual CPUs to memory than other families but share the NCs (Node Controllers) with non-optimized ones.
It is recommended to use these type if you are running any CPU-bound scale-out applications.
CC2 instances provide high core count (32 virtual CPUs) and support for cluster networking.
C1 instances are available in smaller sizes and are ideal for scaled-out applications at massive scale.

This family includes the CR1 and M2 VM types and is designed for memory-intensive applications.
It is recommended to use these VM types for performance-sensitive database, where your application is memory-bound.
CR1 VM types provide more memory and faster CPU than do M2 types.
CR1 instances also support cluster networking for bandwidth intensive applications.
M2 types are available in smaller sizes, and are an excellent option for many memory-bound applications.

This Micro family contains the T1 VM type.
The T1 micro provides a small amount of consistent CPU resources and allows you to increase CPU capacity in short bursts when additional cycles are available.
It is recommended to use this type of VM for lower throughput applications like a proxy server or administrative applications, or for low-traffic websites that occasionally require additional compute cycles. It is not recommended for applications that require sustained CPU performance.
