PII data
Due to operational or regulatory constraints, Google Cloud clients who are interested in developing or updating their data lake architecture frequently have to keep a portion of their workloads and data on-premises.
You can now completely modernise your data lake with cloud-based technologies while creating hybrid data processing footprints that enable you to store and process on-prem data that you are unable to shift to the cloud, thanks to Dataproc on Google Distributed Cloud, which was unveiled in preview at Google Cloud Next ’24.
Using Google-provided hardware in your data centre, Dataproc on Google Distributed Cloud enables you to run Apache Spark processing workloads on-premises while preserving compatibility between your local and cloud-based technology.
For instance, in order to comply with regulatory obligations, a sizable European telecoms business is updating its data lake on Google Cloud while maintaining Personally Identifiable Information (PII) data on-premises on Google Distributed Cloud.
Google Cloud will demonstrate in this blog how to utilise Dataproc on Google Distributed Cloud to read PII data that is stored on-premises, compute aggregate metrics, and transfer the final dataset to the cloud’s data lake using Google Cloud Storage.
Compile and encrypt private information on-site

PII is present in this dataset. PII needs to be kept on-site in their own data centre in order to comply with regulations. The customer will store this data on-premises in object storage that is S3-compatible in order to meet this requirement. Now, though, the customer wants to use their larger data lake in Google Cloud to determine the optimal places to invest in new infrastructure by analysing signal strength by geography.
Full local execution of Spark jobs capable of performing an aggregation on signal quality is supported by Dataproc on Google Distributed Cloud, allowing integration with Google Cloud Data Analytics while adhering to compliance standards.
The Cloud Storage output shows multiple low-quality signal areas:
| Location | Value |
| Georgefurt, MS | 1.0 |
| Scottside, MA | 1.0 |
| Monroemouth, FL | 1.0 |
| Lake Robert, OH | 1.0 |
| East Lauren, VA | 1.0 |
| Shelleyburgh, CT | 1.0 |
| Buckville, ID | 1.0 |
| Garzaton, WI | 3.32 |
| North Danielle, NY | 3.99 |
| Port Natalie, ID | 5.43 |

Reading PII data with Google Distributed Cloud Dataproc requires various steps to assure data processing and privacy compliance.
To read PII data with Google Distributed Cloud Dataproc, just set up your Google Cloud environment.
- Create a Google Cloud Project: If you don’t have one, create one in GCP.
- Project billing: Enable billing.
- In your Google Cloud project, enable the Dataproc API, Cloud Storage API, and any other relevant APIs.
Prepare PII
- Securely store PII in Google Cloud Storage. Encrypt and restrict bucket and data access.
- Classifying Data: Label data by sensitivity and compliance.
Create and configure Dataproc Cluster
- Create a Dataproc cluster using the Google Cloud Console or gcloud command-line tool. Set the node count and type, and configure the cluster using software and libraries.
- Security Configuration: Set IAM roles and permissions to restrict data access and processing to authorised users.
Develop Your Data Processing Job
- Choose a Processing Framework: Consider Apache Spark or Hadoop.
- Write the Data Processing Job: Create a script or app to process PII. This may involve reading GCS data, transforming it, and writing the output to GCS or another storage solution.
Job Submission to Dataproc Cluster
- Submit your job to the cluster via the Google Cloud Console, gcloud command-line tool, or Dataproc API.
- Check work status and records to guarantee completion.
Compliance and Data Security
- Encrypt data at rest and in transit.
- Use IAM policies to restrict data and resource access.
- Compliance: Follow data protection laws including GDPR and CCPA.
Destruction of Dataproc Cluster
- To save money, destroy the Dataproc cluster after data processing.
Best Practices
- Always mask or anonymize PII data when processing.
- Track PII data access and changes with extensive recording and monitoring.
- Regularly audit data access and processing for compliance.
- Data minimization: Process just the PII data you need.
Conclusion
PII processing with Google Distributed Cloud Dataproc requires careful design and execution to maintain data protection and compliance. Follow the methods and recommended practices above to use Dataproc for data processing while protecting sensitive data.
