What is the best combination of GCP services for transitioning a monolithic application to microservices with efficient CI/CD, scalability, and monitoring capabilities?

*The transition from a monolithic application to microservices on GCP requires a combination of services that support continuous integration and deployment (CI/CD), scalability, and monitoring. Kubernetes Engine is an optimal choice for managing containerized applications and microservices. It offers robust orchestration capabilities, including auto-scaling, self-healing, and load balancing, which are essential for managing microservices efficiently. Cloud Build integrates seamlessly with Kubernetes, providing a powerful and flexible CI/CD platform that automates the building, testing, and deployment of software. Cloud Monitoring (formerly Stackdriver) delivers comprehensive monitoring solutions that offer visibility into the performance, uptime, and overall health of cloud-powered applications. This combination not only ensures a smooth CI/CD pipeline but also facilitates effective monitoring and scalability, crucial for a microservices architecture. Other options either lack the comprehensive CI/CD and monitoring capabilities required for microservices or are more suited to different application architectures, such as monolithic or data analytics-focused applications.*
