NAT Gateway vs VPC Endpoints
NAT Gateway vs VPC Endpoints: Designing Smarter Connectivity for AWS Private Subnets AWS Networking | VPC Architecture | Routing | Security | Cost Optimization The Challenge: Keeping Private Workloads Connected A private subnet is designed to keep AWS resources away from direct inbound internet access. But private resources still need to communicate with other systems. For example, an EC2…
NAT Gateways and VPC Endpoints are two AWS networking solutions that can be used to provide connectivity for private subnets. While both can be part of a private subnet architecture, they serve different purposes and are not interchangeable. NAT Gateways provide outbound internet connectivity for instances in private subnets, allowing them to download updates from public software repositories, access external application services, and retrieve files from other internet destinations.
On the other hand, VPC Endpoints provide a direct, private route to specific AWS services, such as Amazon S3, eliminating the need for a NAT Gateway and incurring no additional usage charge for the endpoint itself. When deciding between NAT Gateways and VPC Endpoints, it's important to consider the specific traffic requirements of your workload and the cost implications of each solution.
