AWS SCP for EC2 type

Question

I want to allow users only to create t2.micro/small/medium for development and allow them to use only spot instances. Have created IAM policy to restrict type/size of instances. In addition I want to put restriction on "on-demand" instances (team MUST opt for spot instances only). What is the cleaner way of achieving it?

Answer 1

allow full access with the account

      "Action": [
        "ec2:RunInstances",
        "cloudwatch:DescribeAlarms"
      ],
      "Resource": [
        "arn:aws:ec2:*:*:instance/*"
      ],
      "Condition": {
        "ForAnyValue:StringNotLike": {
          "ec2:InstanceType": [
            "t3.*",
            "t2.*"
          ]
        }
      }
    }
  ]
