Professional Cloud Developer
To begin integrating applications, you must first have a Google Cloud project. Selecting an existing project requires no special role, but creating a new project requires the Project Creator role (roles/resourcemanager.projectCreator). This role provides the permissions to generate a new resource environment where services can be managed. If you are only testing, creating a temporary project allows you to delete all resources easily afterward to avoid extra costs. Once a project is ready, you must enable specific APIs to consume Google Cloud services.
The Service Usage Admin role (roles/serviceusage.serviceUsageAdmin) is required to activate or deactivate these services. This role includes the serviceusage.services.enable permission, which allows the project to communicate with Google’s external APIs. Without this specific access, applications cannot interact with cloud-based resources like Compute Engine or Cloud Storage.
Managing how applications authenticate requires the use of service accounts. To build these identities, an administrator needs the Service Account Creator role (roles/iam.serviceAccountCreator). Additionally, the Service Account User role (roles/iam.serviceAccountUser) is essential for allowing users or services to run tasks as that specific account. This ensures that each application has the correct level of access to perform its designated functions.
Different services require unique predefined roles to function correctly within a project. For example, a developer might need the following roles:
Granting these specific permissions ensures that the principle of least privilege is maintained while still allowing full service consumption. Permissions can be managed through the Google Cloud console or the gcloud CLI using policy binding commands. While basic roles like Viewer or Editor exist, they are not recommended for production environments due to their broad access. Instead, administrators should evaluate the security implications of each role to protect the resource environment. Properly assigning roles to the correct principals is the final step in enabling secure service management.
A Google Cloud project acts as a container for resources and provides an isolation boundary for managing services. To use most services, you must first enable the specific APIs within your project, which associates them with your account and monitoring tools. This process requires the Service Usage Admin role, which provides the specific permissions needed to activate or deactivate services as your application needs change. Many Google Cloud APIs require active billing to function, especially those that charge for high-volume usage. You must associate a valid billing account with your project to ensure that your enabled services remain operational and accessible. If you choose to disable billing for a project, Google Cloud will automatically shut down the resources linked to that project to prevent further charges.
Quotas are hard limits set on the amount of resources or API requests your project can use over time to prevent unexpected costs and resource exhaustion. Monitoring these limits through usage telemetry dashboards helps developers maintain application availability and manage efficiency. It is important to remember that having an available quota does not guarantee that the physical resource is currently available in a specific region or zone.
When your application grows and needs more resources, you can manually request a quota increase through the Google Cloud console. Alternatively, you can enable the Quota Adjuster, an automated tool that monitors your usage and submits adjustment requests on your behalf when you approach your limits. To manage these settings effectively, developers should:
The relationship between enabled services and quotas is critical because some Identity and Access Management (IAM) roles only become visible after the associated API is turned on. For example, you cannot grant a user a Compute Engine role until the Compute Engine API is active in the project. By carefully managing the lifecycle of these services, you ensure that your application has the right permissions and resources to scale successfully.
Google Cloud Console, gcloud CLI, and the Service Usage API are the primary tools used for service activation. Before enabling any service, you must verify that billing is enabled for your Google Cloud project. This ensures that the resources consumed by the APIs can be properly managed and charged. To manage these services, you need specific IAM roles such as the Service Usage Admin (roles/serviceusage.serviceUsageAdmin). This role provides the serviceusage.services.enable permission, which is required to turn on specific features. Assigning the correct permissions is a vital step in the lifecycle of managing Google Cloud resources.
The gcloud CLI allows developers to enable services quickly using the gcloud services enable command. You should first run gcloud init to initialize the environment and ensure you are working within the correct project. Commonly enabled APIs include:
Many Google Cloud features have API Dependencies, meaning one service requires other related APIs to function correctly. For example, a complex deployment might require enabling the Cloud Run, Cloud Build, and Eventarc APIs simultaneously. Identifying and managing these relationships early prevents errors during the application integration process.
Managing the service lifecycle also involves using the Project Creator role to set up new environments for development. If you no longer need the resources, you can delete the project to remove all associated services and stop further billing. Developers must also monitor quotas to ensure the project has enough capacity for its specific deployment needs.
