- AWS VPC networking and NAT Gateways can lead to unexpected high costs if not configured properly.
- A missing VPC Endpoint for S3 caused data transfers to route through NAT Gateway, incurring $1,000 in charges.
- VPC Gateway Endpoints for S3 provide a free, direct route from VPC to S3, bypassing NAT Gateway charges.
- AWS Cost Anomaly Detection helped identify the issue early, preventing larger unexpected costs.
- Always validate cost assumptions and test configurations with small data transfers before scaling.
- VPC Endpoints are essential for cost-effective and efficient communication between EC2 and AWS services like S3.
- Even experienced AWS users can encounter unexpected costs due to the platform's complexity.
