The following legacy instance types are available, but their use is discouraged:
-
T2_SMALL: A t2.small instance type.
-
T2_MEDIUM: A t2.medium instance type.
-
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_12XRequired: Yes
