QuestionQ295

Ensuring solution and operations excellence

For this question, use the EHR Healthcare case study. Because infrastructure administration costs are increasing, you want to migrate the legacy relational database systems to Google Cloud. You must maintain the strict uptime requirements with limited in-house expertise. What should you do?

  • A Use the Database Migration Service (DMS) to migrate the MySQL databases to Cloud SQL.
  • B Backup and restore the databases to Cloud SQL instances with minimal changes.
  • C Leverage AlloyDB to migrate the on-premises databases.
  • D Set up database replication to Cloud SQL instances using native database tools, and incrementally switch applications to use the replicas.
Explanation

Database Migration Service provides a managed migration path from MySQL to Cloud SQL, including an initial data load and continuous replication for a low-downtime cutover. Cloud SQL reduces database-administration effort and supports regional high availability, making it appropriate for stringent availability requirements with limited operational expertise.
