Answer: Implement managed instance groups for the Tomcat and Nginx. Migrate MySQL to Cloud SQL, RabbitMQ to Cloud Pub/Sub, Hadoop to Cloud Dataproc, and NAS to Cloud Storage.
The correct answer is D. This solution leverages managed instance groups for Tomcat and Nginx, which ensures automatic scaling without significant modifications to the applications. Migrating MySQL to Cloud SQL ensures compatibility with the existing database, while RabbitMQ to Cloud Pub/Sub, Hadoop to Cloud Dataproc, and NAS to Cloud Storage offer managed services that optimize performance and costs. Cloud Storage is ideal for storing large quantities of unstructured data like images, logs, and backups, which aligns with Dress4Win's needs and maximizes ROI.
