Choreography vs orchestration in microservices and best practices

We went from a single monolith to a set of microservices that are small, lightweight, and easy to implement. Microservices enable reusability, make it easier to change and scale apps on demand but they also introduce new problems. How do microservices interact with each other toward a common goal? How do you figure out what went wrong when a business process composed of several microservices fails? Should there be a central orchestrator controlling all interactions between services or should each service work independently, in a loosely coupled way, and only interact through shared events?

Orchestrating microservices with Google Cloud Workflows

The trend toward splitting a monolith into fine-grained loosely-coupled microservices has its merits. It allows us to scale parts of an application more easily. Teams become more effective on their focused perimeter. However, in a chain or graph of services interacting with each other via message buses or other eventing mechanisms, it becomes difficult to understand when things start to break. Your business processes spanning those services are in limbo. Here starts detective work to find out how to get back on track. Read more...
