A provider may offer a limited resource allowance without a recurring compute charge, subject to account and capacity rules.
A small instance may be free only within specific resource, usage, region, or account limits.
A temporary campaign can reduce the effective price to zero for a limited period. It is not the same as permanent free service.
Some programs offer temporary testing access, often with limited stock and changing eligibility.
