Serve a simple promotional website (100–500,000 daily clicks) while minimizing operational management. Which two infrastructure choices do you recommend?

For a promotional website with 100,000–500,000 daily clicks, minimizing operational management is key. App Engine is a fully managed platform-as-a-service (PaaS) that automatically scales and handles infrastructure, making it ideal for low operational overhead. Cloud Datastore is a NoSQL document database that is also fully managed and scales automatically, suitable for user data without complex administration. A managed instance group (MIG) with Compute Engine instances provides auto-scaling and auto-healing, reducing management compared to individual VMs. Cloud Bigtable is a fully managed NoSQL wide-column database, excellent for high-throughput data and minimal operational burden. GKE requires more operational management for cluster maintenance and container orchestration. A single Compute Engine VM is not scalable or highly available for this traffic volume and requires significant manual management.
