How many microservices do you have in Go, and how often do tasks involving two microservices occur?

The number of microservices in Go depends on the architecture and size of the project — usually from a few to dozens.

Tasks involving two or more microservices are quite common, especially when:

• Ensuring data consistency between services.
• Implementing business processes that are distributed across different services (e.g., order and payment).
• Integrating with external systems.

For such tasks, inter-service communication patterns are used: REST/gRPC calls, asynchronous messages via brokers (Kafka, RabbitMQ), as well as transaction management patterns like Saga.

The frequency of such tasks depends on the degree of coupling between microservices and business logic, but in mature systems, inter-service interaction is common, and the architecture is built with this in mind.
