Cloud VPN Overview

1. Cloud VPN Overview

Use Cloud VPN when you don't need the connection speed of Cloud Interconnect. Cloud VPN is cheaper and easier to set up than Cloud Interconnect. Thus, Cloud VPN is useful for low-volume or low-bandwidth data connections. When you prefer the economics of an IPSec tunnel over the Internet, and when your network infrastructure cannot support dedicated fiber connections to Google Cloud, choose Cloud VPN. You can also use Cloud VPN to encrypt data in transit. With Cloud VPN, you can selectively advertise routes between VPC networks. In contrast, when you set a peering between two VPC networks, all the subnet routes are advertised. Cloud VPN securely connects your peer network to your virtual private cloud or VPC network through IPSec tunnels. The data is encrypted as it passes through the tunnels. The traffic traveling between the two networks is encrypted by one VPN gateway and then decrypted by the other VPN gateway. This action protects your data as it travels over the Internet. There are two types of Cloud VPN: high availability VPN or HA, and classic VPN. Google Cloud VPN primarily offers HA VPN; the recommended solution for dynamic routing and enhanced reliability. Classic VPN is available for specific use cases requiring static routing. Next, let's discuss both Cloud VPN products. Jack is responsible for optimizing the company's cloud infrastructure, and he's currently focused on updating their networking strategy within Google Cloud. Symbol Corporation has been relying on classic VPNs to connect their on-premises data center to Google Cloud, but they've experienced occasional connectivity issues. Now they are looking to enhance our network reliability and performance. Considering the critical nature of Symbols operations, the switch to high-availability VPNs and Google Cloud will be suitable. The company's applications demand a highly available, secure connection to Cloud services and a simplified setup. HA VPNs could provide the necessary redundancy and failover capabilities to ensure uninterrupted connectivity. The advantages of HA VPNs over classic VPNs include improved availability, automatic failover, and better performance. The switch to HA VPN will meet the networking requirements and contribute to a more resilient and efficient infrastructure.
