The question requires selecting two compute products that are both cloud-native, no-ops (minimal operational overhead), and auto-scaling. Based on the community discussion and Google Cloud best practices:

• B (Google Kubernetes Engine with containers): GKE, especially in Autopilot mode, is managed by Google, handling cluster operations, scaling, and updates, reducing operational overhead. It supports auto-scaling of nodes and pods, aligning with cloud-native principles. This is supported by high upvotes and comments emphasizing its managed nature and suitability for modern applications.

• C (Google App Engine Standard Environment): App Engine Standard is a fully managed Platform-as-a-Service (PaaS) offering, requiring no infrastructure management. It automatically scales instances based on demand, providing a true no-ops experience. Comments highlight its serverless nature and automatic scaling capabilities.

Other options are less suitable:

• A (Compute Engine with containers): Requires manual management of VMs and containers, not no-ops.
• D (Compute Engine with custom instance types): Involves VM management and lacks built-in auto-scaling without additional setup.
• E (Compute Engine with managed instance groups): While MIGs offer auto-scaling, they still require operational overhead for image management, updates, and infrastructure maintenance, making them less no-ops compared to B and C. Community debates note that MIGs are not truly serverless or cloud-native.

The consensus (65% for BC) and highly upvoted comments reinforce that B and C best meet the no-ops and auto-scaling requirements for a cloud-native solution.
