Some services provides up to a certain threshold of free services, and then charges, as well as expires after 12 months. For example, EC2 provides 750 hours per month of compute capacity for the first 12 months free, and S3 provides 5GB of standard storage for free for 12 months. Both will charge for those same capacities after 12 months.
