--
-- -   'supported-platforms': Indicates whether your account can launch
--     instances into EC2-Classic and EC2-VPC, or only into EC2-VPC.
--
-- -   'default-vpc': The ID of the default VPC for your account, or
--     'none'.
--
-- -   'max-instances': The maximum number of On-Demand instances that you
--     can run.
--
-- -   'vpc-max-security-groups-per-interface': The maximum number of
--     security groups that you can assign to a network interface.
--
-- -   'max-elastic-ips': The maximum number of Elastic IP addresses that
--     you can allocate for use with EC2-Classic.
--
-- -   'vpc-max-elastic-ips': The maximum number of Elastic IP addresses
--     that you can allocate for use with EC2-VPC.
