VPN CloudHub leverages AWS's Virtual Private Gateway to connect multiple VPN connections from different remote sites (spokes) to a central hub (hub-and-spoke model). This setup allows the remote sites to communicate with each other as well as with the central VPC, providing a cost-effective and scalable solution for secure multi-site connectivity.
Key Characteristics:
Hub-and-Spoke Model: The central AWS VPC acts as the hub, with multiple remote sites (spokes) connected to it. Mesh Network: Enables communication between the remote sites through the central VPC, creating a mesh network without needing direct peering between each pair of sites. Ease of Management: Simplifies the management of multiple site-to-site VPN connections by centralizing the control through the VPC.
Key points:
Use this design if you have multiple branch offices and existing internet connections and would like to implement a convenient, potentially low-cost hub-and-spoke model for primary or backup connectivity between these remote offices. VPN CloudHub is used for hardware-based VPNs and allows you to configure your branch offices to go into a VPC and then connect that to the corporate DC (hub and spoke topology with AWS as the hub). Can have up to 10 IPSec tunnels on a VGW by default. Branches can talk to each other (and provides redundancy). Can have Direct Connect connections. Hourly rates plus data egress charges.
Use Cases for VPN CloudHub
Multi-Branch Office Connectivity: Scenario: A company with several branch offices distributed across different geographical locations needs secure and reliable communication between these branches and the central office. Solution: Using VPN CloudHub, each branch office sets up a VPN connection to the AWS VPC. The hub-and-spoke model allows all branch offices to communicate with each other and the central office through the AWS VPC. Centralized Resource Access: Scenario: An organization has multiple remote sites that need access to centralized resources hosted in an AWS VPC, such as databases, application servers, and file storage. Solution: By connecting each remote site to the VPC using VPN CloudHub, all sites can securely access the centralized resources without the need for redundant infrastructure. Disaster Recovery and Backup: Scenario: Branch offices require a reliable disaster recovery solution and need to backup critical data to a central location regularly. Solution: VPN CloudHub allows all branch offices to securely transmit backup data to a centralized location in the AWS VPC, ensuring data redundancy and recovery capabilities. Scalable and Cost-Effective Networking: Scenario: A growing business is expanding its number of branch offices and needs a scalable solution for secure site-to-site connectivity. Solution: VPN CloudHub provides a scalable architecture where new branch offices can be easily added by establishing additional VPN connections to the VPC, avoiding the complexity and cost of a fully meshed VPN network. Cross-Region Communication: Scenario: An international company with branch offices in different regions needs to ensure secure and efficient communication between these offices. Solution: Using VPN CloudHub, the company can connect remote sites from different regions to a central VPC, enabling cross-region communication without compromising security or performance. Benefits of Using VPN CloudHub
Centralized Management: Simplifies network management by centralizing the connections through a single VPC. Scalability: Easily accommodates additional remote sites by adding new VPN connections to the VPC. Cost-Effective: Reduces the need for complex and expensive direct peering arrangements between every pair of sites. Security: Ensures secure communication between remote sites and the central VPC using IPsec VPN tunnels. Flexibility: Supports various routing options and configurations to meet specific network requirements.
