11-03 EC2 Instance Types

Last updated Aug 17, 2023 Edit Source

An instance type is a particular  instance size and instance family.

Example

t2.micro

• t2 is the instance family
• micro is the instance size
  together they make up an instance type

A common pattern for instance sizes:

• nano
• micro
• small
• medium
• large
• xlarge
• 2xlarge
• 4xlarge
• 8xlarge
• ….

There are many exceptions to this pattern for sizes e.g.

• c6g.metal – is a bare metal machine.
• C5.9xlarge – Is not a power of 2 or even number size

EC2 Instance Sizes generally double in price and key attributes
