Answer: Deploy the Docker containers into Cloud Run.
**D is correct** because Cloud Run is a managed service that requires minimal administration. It allows for automatic scaling according to load, making it an ideal choice for deploying microservices. Cloud Run abstracts away infrastructure management, automatically scaling up or down based on traffic. This option provides the best balance between scalability and minimal administrative overhead. **A is incorrect** because managed instance groups require more administration than Cloud Run. This approach would necessitate manual scaling and administration, lacking the automatic scalability feature of Cloud Run. **B is incorrect** as, although Google Kubernetes Engine (GKE) offers scalability, it demands more management than Cloud Run. GKE requires manual scaling and configuration, making it less suitable for scenarios aiming for minimal administration. **C is incorrect** because combining the services into a single Docker image and deploying on App Engine may not offer optimal scalability. This approach could lead to a monolithic architecture, contrary to microservices principles, and might not scale as efficiently as Cloud Run.

As a member of a team developing a Cloud Access Security Broker application for enterprises, you're tasked with managing the user-management service. This service consists of multiple microservices handling add, update, delete, and list operations, each running in separate Docker containers. What is the best way to deploy these microservices on GCP to ensure scalability with minimal administration?
A
Deploy each Docker container in a separate managed instance group.
B
Deploy the Docker containers into Google Kubernetes Engine.
C
Combine the four services into a single Docker image and deploy it on App Engine.
D
Deploy the Docker containers into Cloud Run.
