Worked example. The correct answer is already marked and every option is explained below, so there is nothing to select here. To answer questions yourself, start the free trial.
An enterprise operates an on-premises monolithic application running on virtual machines. The application consists of a public HTTP web frontend with unpredictable traffic spikes, along with a stateful inventory backend that requires specialized operational controls and custom storage configurations. Deployments currently suffer from long lead times, and resource utilization is inefficient because compute capacity must remain over-provisioned to handle peak traffic.
You are tasked with architecting a cloud-first modernization strategy on Google Cloud that refactors the architecture into cloud-native patterns to enhance agility, enable fine-grained autoscaling, and optimize compute resources.
Which refactoring strategy should you recommend?
This strategy decomposes a monolithic application into loosely coupled microservices by aligning specific application tiers with the most suitable cloud-native container execution environments. The user-facing HTTP components are refactored into stateless containers deployed to Cloud Run, while complex, stateful components are isolated and hosted on Google Kubernetes Engine (GKE).
Mixing Cloud Run for stateless HTTP microservices with GKE for stateful or orchestrator-dependent services is the recommended Google Cloud pattern for modular application modernization. It leverages serverless agility where elasticity is needed while retaining deep Kubernetes control where complex storage and operational configurations are required.
