NAT Gateway

The link between EC2-NAT-Gateway and EC2-Network-Interface in Amazon Web Services (AWS) is that they are both essential components of virtual private cloud (VPC) networks. EC2-NAT Gateway provides a secure internet connection for resources within the VPC, while EC2-Network Interface allows the resources to communicate with other devices on the public internet. Together, they form a secure connection between the two networks which allows users to access resources from either side. This type of configuration is critical for organizations that rely heavily on cloud computing, as it ensures their data remains secure and protected.

The link between Amazon EC2-NAT Gateway and EC2-Subnet in Amazon Web Services (AWS) is that the former provides an interface for network traffic to flow between the public internet and private subnets. The NAT Gateway sits inside the public subnet, while the EC2-Subnet is made up of private IP addresses that are not accessible from outside of the cloud environment. When a request is sent to a resource within an EC2-Subnet, such as an application server or database, it must pass through a NAT Gateway before reaching its destination. This ensures that all incoming requests are authenticated and secure. The NAT Gateway also provides access to external services such as DNS services, email servers, and other cloud resources. In short, it acts as a gateway between your private network resources and the public internet.

The link between Amazon Web Services' EC2-NAT-Gateway and EC2-VPC services is a critical one. The former enables outbound internet connectivity for instances within the VPC, while the latter allows for resources to securely communicate with each other in a private, isolated environment. In essence, EC2-NAT-Gateway serves as the "gatekeeper" for traffic flowing from a VPC to external networks. It does this by allowing outbound connections from private IP addresses and routing traffic back into the VPC via an IGW (internet gateway). By taking advantage of both services together, customers can ensure secure communication between resources that remain within their own virtual networks.

The link between an Elastic Compute Cloud (EC2) NAT Gateway and an Internet Protocol (IP) address in Amazon Web Services (AWS) is one of connectivity. EC2 NAT Gateways are used to facilitate communication between the external internet and resources running within the AWS infrastructure. To do this, they must be associated with a public IP address to serve as a bridge for traffic. This allows AWS users to securely access their resources from outside the VPC, while also protecting those resources from potential malicious activity originating from the public internet.
