Coordinating microservices

When comparing a monolith system with a microservice-based system, one thing is clear. There is more of everything. The individual microservices are simpler and it's much easier to reason, modify, and troubleshoot individual services. But, understanding the whole system, making changes across multiple services, and debugging problems are more challenging. Many more interactions also happen over the network between separate microservices, where, with a monolith, these interactions would occur within the same process. It means that to benefit from microservices, you need a disciplined approach, you need to apply best practices, and have good tools at your disposal.
