Securing Apigee with VPC Peering and External Load Balancer in Google Cloud
Here in this blog, we are going to learn how to secure Apigee with VPC peering and external load balancer in Google Cloud.
Configuring Google Apigee with two different Google Cloud projects, where one is managed by the customer and the other by Google Cloud, using VPC peering and an external load balancer in the customer’s project, provides several key benefits, especially around security, network isolation, and scalability.
- Enhanced Security: By using VPC peering between the two Google Cloud projects, the Apigee Proxy environment is isolated from public internet access, ensuring that APIs can only be accessed within the customer’s private network. This adds an additional layer of security by limiting exposure to external threats and ensuring that sensitive data is transmitted within a trusted environment.
- Control Over Traffic Management: The external load balancer in the customer-managed project allows the customer to have full control over how incoming API traffic is distributed across different resources. This means the customer can enforce strict security policies, manage traffic flows, and direct requests based on specific rules such as geographical location or request type.
- Centralized Network Management: With VPC peering, the customer retains centralized control over their network configurations, ensuring that internal traffic between Apigee and other services in the customer’s environment is highly secure and managed according to organizational standards. This centralized management simplifies troubleshooting and monitoring while providing greater visibility and audit capabilities.
- Cost and Resource Optimization: Having the external load balancer in the customer’s project can also help optimize costs. The customer can take advantage of their existing resources and network setups, while only paying for the Apigee resources managed by Google Cloud. This separation allows for better resource allocation and scalability without over-provisioning.
Overall, this architecture improves the security, control, and flexibility of the API management environment while leveraging the strengths of both Google Cloud and the customer’s infrastructure.
