Question
Your team plans to use AlloyDB as their database backend for an upcoming application release. Your application is currently hosted in a different project and network than the AlloyDB instances. You need to securely connect your application to the AlloyDB instance while keeping the projects isolated. You want to minimize additional operations and follow Google-recommended practices. How should you configure the network for database connectivity?
A. Provision a Shared VPC project where both the application project and the AlloyDB project are service projects.
B. Use AlloyDB Auth Proxy and configure the application project’s firewall to allow connections to port 5433.
C. Provision a service account from the AlloyDB project. Use this service account’s JSON key file as the –credentials-file to connect to the AlloyDB instance.
D. Ask the database team to provision AlloyDB databases in the same project and network as the application.
Answer
A. Provision a Shared VPC project where both the application project and the AlloyDB project are service projects.
Explanation
When your application and AlloyDB database instances are hosted in different projects and networks, the Google-recommended best practice is to provision a Shared VPC (Virtual Private Cloud) project where both the application project and the AlloyDB project are configured as service projects.
Shared VPC allows you to connect resources from multiple projects to a common VPC network, enabling secure communication between them as if they were part of the same project. This approach offers several advantages:
- Security: Shared VPC provides a centralized network configuration, allowing you to define consistent network policies and firewall rules across projects.
- Isolation: Each project remains isolated, with its own resources and access controls, while sharing the same VPC network.
- Simplified management: With Shared VPC, you can manage the network configuration in a single project, reducing operational overhead and complexity.
- Efficient connectivity: Resources in service projects can communicate with each other using internal IP addresses, eliminating the need for external IP addresses or additional networking setup.
By provisioning a Shared VPC project and adding your application project and AlloyDB project as service projects, you can securely connect your application to the AlloyDB instances while keeping the projects isolated. This approach aligns with Google’s recommended practices for cross-project communication and minimizes additional operational tasks.
The other options mentioned, such as using AlloyDB Auth Proxy, service account JSON key files, or provisioning AlloyDB in the same project, may introduce additional complexity, security risks, or deviate from recommended practices.
In summary, leveraging Shared VPC is the most secure, efficient, and Google-recommended approach for connecting your application to AlloyDB instances across different projects.
