Free tier Billing

While the AWS Free Tier offers many services at no cost, it's important to understand that not all AWS resources are included in the free tier, and some limitations apply even for eligible services.

Regarding Elastic IP addresses, they are not included in the AWS Free Tier offer. Here's what you need to know:

1. Elastic IP addresses are chargeable when they are not associated with a running EC2 instance or when they are associated with a stopped instance.

2. You won't be charged for an Elastic IP address if it's the only one associated with a running EC2 instance.

3. If you have multiple Elastic IP addresses or if the Elastic IP is not attached to any instance or network interface, you will incur charges.

It's crucial to be aware of these conditions to avoid unexpected costs. Even if you're using the Free Tier, you may still be charged for Elastic IP addresses if they're not properly managed.

To minimize costs while learning and experimenting with AWS:

1. Release Elastic IP addresses when not in use.
2. Ensure your Elastic IP is associated with a running EC2 instance.
3. Use only one Elastic IP per running instance to stay within the free usage.
4. Set up budget alerts to notify you if your usage exceeds defined thresholds.

Remember, the Free Tier has limits and conditions. Always monitor your usage and understand which resources are truly free to avoid unexpected charges.
