I understand your frustration with unexpected charges on your AWS account, especially when you believe you're operating within the Free Tier limits. Let me explain some possible reasons for these charges and provide some suggestions:
-
T3 vCPU Credits: Even if you're within the Free Tier, T3 instances can incur charges if they use more CPU credits than allocated. This can happen if your application is CPU-intensive or if there's a misconfiguration causing high CPU usage.
-
VPC IPv4 Addresses: AWS now charges for public IPv4 addresses, even within the Free Tier. If your instances or other resources are using public IPs, you may see these charges.
-
Elastic Load Balancer: Load balancers are not fully covered by the Free Tier and can incur charges.
-
S3 Storage: While S3 has some Free Tier allowance, storing large files (like videos) might exceed this limit.
To address these issues:
-
Review your EC2 instance types and ensure they align with Free Tier offerings (t2.micro or t3.micro in some regions).
-
Monitor your CPU credit usage and consider optimizing your application if it's consuming too many credits.
-
Use private IPs where possible to avoid charges for public IPv4 addresses.
-
Be cautious with services not fully covered by Free Tier, like load balancers.
-
Set up billing alerts to notify you when you're approaching Free Tier limits.
-
Regularly check the AWS Billing dashboard to understand your usage and charges.
-
If you believe there's an error, contact AWS Support for clarification.
Remember, even if you delete resources, there might be some residual charges for the time they were active. Don't be discouraged – managing cloud resources efficiently is a learning process. With careful monitoring and optimization, you can minimize costs while building your project.
