Analyzing and optimizing technical and business processes

Your company has built a monolithic, three-tier application that lets external users upload and share files. The solution is difficult to enhance and is not reliable. The development team wants to rearchitect the application to use microservices and a fully managed service approach, but must persuade leadership that the effort is valuable. Which advantage(s) should they emphasize to leadership?

  • A The new approach will be significantly less costly, make it easier to manage the underlying infrastructure, and automatically manage the CI/CD pipelines.
  • B The monolithic solution can be converted to a container with Docker. The generated container can then be deployed into a Kubernetes cluster.
  • C The new approach will make it easier to decouple infrastructure from application, develop and release new features, manage the underlying infrastructure, manage CI/CD pipelines and perform A/B testing, and scale the solution if necessary.
  • D The process can be automated with Migrate for Compute Engine.
Explanation

Microservices create loosely coupled components that can be developed, deployed, released, and scaled independently, improving change velocity and resilience compared with a tightly coupled monolith. Fully managed services reduce the operational burden of underlying infrastructure, and managed delivery tooling can provide CI/CD and traffic-splitting capabilities for controlled releases and A/B testing. Google Cloud documents independent deployment and scaling for modular services, managed infrastructure benefits, and deployment traffic splitting.
