VPC to VPN Automatic Access via Gateway Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method for accessing a virtual private network (VPN) by a virtual private cloud (VPC) requires manual configuration, resulting in high time and economic costs due to the need for manual creation and management of VPN instances during dynamic creation and cancellation of VPCs.
Innovation Solution
A method and apparatus that automatically access a VPN by a VPC, involving the receipt of configuration information, creation of a VPN instance, binding the VPC to the instance, and sending configuration information to the network side provider edge (PE) to configure an upper layer VPN instance, thereby establishing a VPN connection without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration method is used for VPC access to VPN, then network security and control are improved, but time cost and operational complexity increase significantly
Solution Approach 1:
The system enables automatic self-configuration of VPN instances through programmatic interfaces. When a VPC needs to access a VPN, the system automatically creates the necessary VPN instances, establishes binding relationships, and configures routing without requiring manual intervention, thus reducing time cost while maintaining security through automated policy enforcement
Solution Approach 2:
The system pre-establishes templates and configurations for VPN instances before they are actually needed. When access is required, the system retrieves pre-configured templates and instantiates them automatically, avoiding the need for manual setup and reducing the time required for VPN access establishment
2Manufacturing precision
If manual creation of VPN instances is required, then configuration accuracy is improved, but operational efficiency and productivity deteriorate
Solution Approach 1:
The system implements automated feedback mechanisms that verify configuration correctness after automatic VPN instance creation. The system validates binding relationships between VPCs and VPN instances, checks routing configurations, and ensures network connectivity, thereby maintaining configuration accuracy while achieving automated deployment
Solution Approach 2:
The system uses parameterized templates that allow automatic substitution of configuration values based on input parameters. Instead of manual configuration, the system automatically instantiates VPN instances with correct parameters by retrieving and processing configuration templates, maintaining accuracy through automated parameter validation and substitution
3Adaptability or versatility
If dynamic creation and cancellation of VPC occurs, then system flexibility and adaptability are improved, but management complexity and operational burden increase
Solution Approach 1:
The system implements dynamic VPN instance management that automatically adapts to VPC creation and cancellation events. When a VPC is created or cancelled, the system automatically triggers corresponding VPN instance creation or deletion operations, maintaining flexible system operation without increasing management complexity through automation
Solution Approach 2:
The system establishes event-driven feedback mechanisms that automatically respond to VPC lifecycle events. When VPCs are created or cancelled, the system receives notifications and automatically performs corresponding VPN configuration changes, ensuring consistent state management and reducing operational burden through automated event response

AI summary
Embodiments of the present invention disclose a method, an apparatus and a system for accessing a virtual private network by a virtual private cloud. A data center breakout gateway receives first configuration information; creates a first VPN instance according to identifier information of the VPN; determines VPC according to parameter information of the VPC, and binds the VPC to the first VPN instance; and sends second configuration information to the network side PE according to address information of the network side PE, where the second configuration information includes the identifier information of the VPN, so that the network side PE configures an upper layer VPN instance for the first VPN instance on the network side PE according to the identifier information of the VPN. In the embodiments of the present invention, the problem of automatically accessing the virtual private network by the virtual private cloud is solved.
