You can attach a VGW to your VPC and your customer gateway, creating a secure communication path. Each VGW can support multiple VPN connections to a single VPC; as a result, you can achieve redundancy on both the AWS side and the customer gateway side. Use cases for a Virtual Private Gateway include establishing secure communication between your VPC and on-premises networks, extending your internal network to AWS, and building a hybrid cloud architecture by connecting on-premises resources to AWS resources within an Amazon VPC.
Guide: Virtual Private Gateways (VGWs)
What is a Virtual Private Gateway (VGW)? A Virtual Private Gateway (VGW) is the Amazon endpoint that serves as a bridge between an Amazon VPC and an on-premises network over a Direct Connect or VPN connection. It ensures safe and private connectivity between AWS and your infrastructure.
Why is it important? VGWs are significant for maintaining the security and privacy of the data traffic from AWS. It forms an essential part of creating a VPN connection, ensuring the privacy of your cloud infrastructure.
How does it work? A VGW routes traffic from a VPC to an on-premises network over an established VPN connection or Direct Connect. By providing two VPN endpoints for automatic failover, it ensures high availability.
Exam Tips: Answering Questions on Virtual Private Gateways (VGWs) 1. Understanding the Role: VGW acts as the VPN concentrator on the Amazon side of the VPN connection. 2. High Availability: Remember that VGWs provide two VPN endpoints for automatic failover. 3. Combination: VGWs could be used either with Direct Connect or VPN Connection. 4. AWS Documentation: Be sure to familiarize yourself with the VGW in AWS's official documentation. Many exam questions originate from there. 5. Scenario Based Questions: In exams, expect scenario-based questions where you will need to identify if a VGW, Internet Gateway or other gateway service is required. Practice these scenarios to understand VGWs better.
