Question 4
A financial institution is planning to migrate its core banking system from a legacy mainframe to Google Cloud. The system is critical, handling daily transactions for millions of customers. The institution also needs to integrate this system with modern cloud-based services for data analytics, fraud detection, and customer engagement. The migration must be done in phases to avoid disruptions to banking services. Additionally, the institution must comply with stringent regulatory requirements, including data residency and security protocols. Which two strategies should you incorporate into your migration plan to meet these requirements? (Choose two)
-
A
Implement a data masking strategy for sensitive data during the migration process to comply with regulatory requirements.
-
B
Set up a hybrid environment with interconnectivity between the mainframe and Google Cloud using Cloud VPN.
-
C
Use Transfer Appliance to securely move large datasets from the mainframe to Google Cloud Storage for backup and archival.
-
D
Migrate the entire core banking system to Google Cloud Spanner in a single cutover.
-
E
Use Google Cloud's Anthos to extend the mainframe's services to the cloud while gradually migrating individual components.
Reveal correct answers
Correct answers: A, E
A.
Implementing data masking ensures that sensitive data is protected during the migration process, which is crucial for compliance with regulatory requirements. This strategy mitigates the risk of data breaches and ensures that customer information is kept secure throughout the migration. Data masking can be applied to test environments to protect data while validating the migration.
B.
While setting up a hybrid environment with Cloud VPN provides secure connectivity between the on-premises mainframe and Google Cloud, this option alone does not sufficiently address the need for phased migration and seamless integration with modern cloud services. VPN connections may also introduce latency issues, which can be problematic for real-time banking transactions.
C.
While Transfer Appliance is a secure and efficient tool for moving large datasets, this strategy focuses on data transfer for backup and archival purposes rather than the active migration of the core banking system itself. It does not address the need for real-time integration and phased migration of the operational components of the system.
D.
A single cutover migration of the entire core banking system introduces high risk, especially given the critical nature of the system. Any issues during the migration could result in significant downtime, affecting millions of customers. Moreover, a single cutover does not provide an opportunity to test and validate the system in the new environment, which is crucial for such a sensitive application.
E.
Anthos allows you to modernize the core banking system incrementally by enabling a hybrid environment where the mainframe's services can be extended to the cloud. This approach supports phased migration, allowing individual components to be migrated and tested in the cloud while maintaining the overall system's functionality. Anthos also provides consistency across environments, easing the transition and reducing the risk of disruption.
