This PD and bucket data is encrypted using a Google-generated data encryption key (DEK) and key encryption key (KEK). The CMEK feature allows you to create, use, and revoke the key encryption key (KEK). Google still controls the data encryption key (DEK). For more information on Google data encryption keys, see Encryption at Rest.

To establish a reliable, cloud-native, and scalable process for updating nodes in your GKE clusters, configuring node auto-upgrades within designated maintenance windows is the most effective approach.​

Option A: Migrating to a self-managed Kubernetes environment would increase operational overhead and complexity, as your team would be responsible for managing the entire infrastructure, including patching and updates. This contradicts the goal of adopting a cloud-first strategy and does not inherently provide a more reliable update process.​

Option B: Developing custom scripts for patch management introduces potential risks and maintenance burdens. Ensuring the reliability, security, and scalability of such scripts can be challenging, and this approach may not align with best practices for managing GKE environments.​

Option C: Scheduling daily reboots does not guarantee that nodes will apply the latest patches or updates. Without a mechanism to manage and apply updates, reboots alone are insufficient to maintain node security and compliance.​

Option D: Configuring node auto-upgrades ensures that GKE automatically keeps your nodes up-to-date with the latest stable versions, reducing the risk of missed critical patches. By setting maintenance windows, you can control when these upgrades occur, minimizing disruptions to your workloads. This approach leverages GKE's managed services to maintain security and compliance efficiently.​

Therefore, Option D is the optimal solution, as it aligns with a cloud-first strategy and leverages GKE's native capabilities to automate and schedule node updates effectively.​

To minimize the usage of service account keys and implement Workload Identity Federation (WIF) with your on-premises identity provider, you can use a workload identity pool integrated with your corporate Active Directory Federation Service (ADFS). This setup allows your on-premises Windows-based applications to authenticate to Google Cloud APIs without using long-lived service account keys.

Set Up a Workload Identity Pool:

In the Google Cloud Console, go to IAM & Admin > Workload Identity Federation.

Create a new workload identity pool.

Configure the pool to trust your corporate ADFS by specifying the federation provider details.

Create a Workload Identity Provider:

Within the created pool, set up a new provider for ADFS.

Configure the provider with the necessary details such as the issuer URL and credentials.

Configure Impersonation Rules:

Set up rules to allow principals in the workload identity pool to impersonate specific Google Cloud service accounts.

This is done by specifying the identity provider and the conditions under which the service accounts can be impersonated.

Update Applications:

Modify your on-premises applications to use the configured ADFS authentication to obtain tokens.

These tokens can then be exchanged for Google Cloud access tokens to interact with Google Cloud APIs securely.

By setting up the workload identity pool and configuring impersonation rules, you achieve secure authentication without needing to distribute and manage service account keys.
