Answer: Move to committed-use instances
Committed use instances offer the lowest cost with a commitment of 1 or 3 years, making them ideal for a project running for 12 months to benefit from the discount. Preemptible instances, while cost-effective for batch processing, are unsuitable due to their interruptible nature, which contradicts the requirement. Standard instances are the most expensive option, and switching to Cloud Functions does not optimize costs due to the overhead of re-platforming the application.
