QUESTION: Based on the constraints and requirements, which migration strategy should you recommend for the core gaming application?
Answer options:
A.
Refactor the application into microservices using Google Kubernetes Engine (GKE) and Cloud Spanner.
B.
Replatform the application to use managed services like Cloud Run and Cloud SQL.
C.
Rehost the application using Migrate for Compute Engine to move VMs as-is.
D.
Retain the application on-premises and use Anthos to manage it.
How to approach this question
Evaluate the 7 R's of migration against the specific constraints: 12-month timeline, limited cloud experience, and need for rapid scaling.
Full Answer
B.Replatform the application to use managed services like Cloud Run and Cloud SQL.✓ Correct
Replatform the application to use managed services like Cloud Run and Cloud SQL.
Replatforming allows the team to use their existing Java/MySQL skills while leveraging managed services (Cloud Run, Cloud SQL) to meet the scaling (5x spikes) and operational (limited ops team) requirements within the 12-month timeframe.
Common mistakes
Choosing Refactor (A) because it represents the 'ideal' cloud-native state, ignoring the business constraints of team skills and timeline.
