  • R4_LARGE: A r4.large instance type.

  • R4_XLARGE: A r4.xlarge instance type.

  • R4_2XLARGE: A r4.2xlarge instance type.

  • R4_4XLARGE: A r4.4xlarge instance type.

  • R4_8XLARGE: A r4.8xlarge instance type.

Type: String

Valid Values: T2_SMALL | T2_MEDIUM | R4_LARGE | R4_XLARGE | R4_2XLARGE | R4_4XLARGE | R4_8XLARGE | SMALL | MEDIUM | LARGE | XLARGE | LARGE_2X | LARGE_4X | LARGE_8X | LARGE_12X
