Learn why NAT Gateway placement in public subnets across all AZs is the AWS-recommended pattern for private subnet internet access, and understand the hidden cost implications of high availability decisions.
A high-level summary: When migrating a web application to AWS that depends on a third-party API with strict IP whitelisting (single CIDR block), the correct solution is to use BYOIP (Bring Your Own IP) with NAT Gateway, not ALB or Global Accelerator. This drill deconstructs why outbound traffic routing—not inbound traffic acceleration—is the critical constraint.
Explore how to architect serverless applications requiring static egress IPs through NAT Gateway versus Internet Gateway alternatives, with FinOps impact analysis for professional-level decision-making.
This drill explores how to reduce cloud spending for a high-security image processing service by optimizing VPC networking—specifically choosing between NAT Gateways and S3 Gateway Endpoints for 1TB daily S3 data transfer.
