Key Questions Answered

What does free PostgreSQL on Fly.io include?
Free PostgreSQL on Fly.io includes 3GB of persistent volume space, which is essential for running small projects. This setup allows developers to utilize LVM block devices and provides a foundation for building applications that require data storage without incurring costs.
How does Fly.io manage data redundancy for PostgreSQL?
Fly.io manages data redundancy by setting up 2-node PostgreSQL clusters for production deployments, ensuring higher availability and data redundancy through isolated NVMe drives. Snapshots of these volumes are also taken to protect against data loss.
Why is a credit card required for free services on Fly.io?
A credit card is required for free services on Fly.io to prevent abuse, such as cryptocurrency mining. This measure helps maintain the integrity of the platform while allowing users to access free resources without immediate charges.
