Option B, Google Kubernetes Engine (GKE) with containers, is a managed Kubernetes service that automatically manages and scales containerized applications. GKE handles cluster management tasks like scaling, upgrades, and security patches, allowing you to focus on the application itself.
Option C, Google App Engine Standard Environment, is a fully managed platform for building and deploying applications. It automatically scales applications based on demand and provides a no-ops experience. With App Engine Standard Environment, you don't need to worry about infrastructure management, as Google handles it for you.
