Google Cloud Platform (GCP) has a key difference from Amazon Web Services (AWS) that can trip up engineers transitioning between the two platforms: the project structure acts as a fundamental boundary in ways that are difficult to change. In AWS, resources are typically housed within a single account, with regions serving as the primary organizational separation.
Moving things around within an account is often feasible, albeit sometimes cumbersome. Conversely, in GCP, the project itself defines the primary billing and access boundary, with many resources being project-specific and unable to be migrated between projects. Examples include Cloud SQL instances, GKE clusters, and persistent disks—these all reside within a single project and cannot be relocated.
This distinction is crucial for optimization efforts, as the tendency to consolidate or reorganize projects may lead to an attempt to move resources that simply cannot be. In such cases, it may be necessary to recreate the resources in the appropriate project and migrate the data, which is a significantly more complex process than simply relocating them.
Before embarking on any optimization project that involves restructuring GCP projects, it is essential to understand which resources are portable and which are not. The migration plan should be built around the immovable resources, not the other way around. Additionally, GCP organizations with a strong security posture employ Organization Policies to control various aspects across all projects.
These policies govern factors such as regions for resource deployment, allowable machine types, and enabled APIs. These policies are put in place for valid reasons, serving to encode security and compliance requirements at the organization level to prevent individual project administrators from overriding them. Understanding these organizational constraints is vital before designing any optimizations.
Designing a solution that cannot be deployed due to these constraints can be frustrating. Therefore, it is advisable to request the active constraint list from the organization administrator before beginning the planning process. Adhering to these constraints, while often necessary, is usually in place for a legitimate reason.
