TechFusion is migrating its legacy data processing application to AWS. The company deploys the application on Amazon EC2 instances located in private subnets within a single VPC.
The application utilizes Amazon S3 for storing both the input and output data. It also uses Amazon DynamoDB to store its application state. The company collects VPC Flow Logs to monitor traffic within the VPC. The company has also considered using Amazon CloudFront to distribute its output data globally for potential performance optimization. The application requires internet access via a NAT Gateway for licensing purposes, using a specific hostname provided by a software vendor.
After reviewing the AWS bill, the company notices that the costs exceed its projected budget. A network engineer analyzes the bill using AWS Cost Explorer and discovers that the primary cause of the unexpected charges is the
USE2-NatGateway-Bytes($)usage type.This is the question!
