A startup is building a new social media application and expects rapid, unpredictable growth in user traffic. The application consists of several stateless microservices and needs to automatically scale from zero to handle millions of requests, without requiring developers to manage the underlying infrastructure. They also prioritize cost efficiency by paying only for resources consumed during active use. Which Google Cloud compute service is the best fit?
- AGoogle Kubernetes Engine (GKE) Autopilot
- BApp Engine Flexible Environment
- CCloud Run
- DCompute Engine with Managed Instance Groups
Show answer & explanationAnswer & explanation
Correct answer: C. Cloud Run
Cloud Run is a serverless platform for stateless containers that automatically scales from zero to meet demand and incurs costs only when requests are being processed. This perfectly aligns with the requirements of rapid, unpredictable growth, minimal infrastructure management, and cost efficiency for stateless microservices.
Why the other options are wrong
- A. GKE Autopilot manages the Kubernetes infrastructure, providing a high degree of automation, but it doesn't scale completely to zero like Cloud Run and might be overkill for simple stateless microservices with no specific Kubernetes needs.
- B. App Engine Flexible Environment offers a PaaS experience but typically has slower cold starts and higher base costs compared to Cloud Run for simple stateless containerized microservices.
- D. Compute Engine with Managed Instance Groups provides auto-scaling VMs, but still requires managing VMs and doesn't scale to zero or offer the same level of serverless abstraction as Cloud Run.
Cloud Run
A fully managed, serverless platform for deploying and scaling containerized applications. It automatically scales from zero to handle traffic and charges only for the resources consumed during active requests.
- Serverless container execution
- Scales automatically from zero
- Pay-per-use billing (cost-efficient)
- Ideal for stateless microservices and web hooks
Memory trick: Cloud Run: Scale from Zero, Pay for Use, Grow Like Crazy.
