Google Cloud offers two primary serverless computing options: Cloud Run and Cloud Run Functions. Cloud Run is a container-based, fully managed serverless platform that allows developers to deploy and scale containerized applications with minimal infrastructure management. It offers features such as flexible scaling, fine-grained billing, HTTP/2 and HTTPS support, custom domains, concurrency, GPU support, VPC connectivity, and event-driven capabilities. In contrast, Cloud Run Functions is a simplified function-as-a-service that focuses on single-purpose functions written in supported languages, primarily designed for event-driven architectures with automatic scaling, simplified development, and focus solely on writing function code without container management. The key differences between the two services include deployment models, abstraction levels, container management, use cases, and pricing models. Cloud Run is suitable for longer-running services, web applications, and complex architectures, while Cloud Run Functions is ideal for short-lived, event-based actions and simple API endpoints. By understanding these differences, developers can choose the right service for their project.
