As applications grow and evolve, even sending an email to a user can become a complex business process that spans days or weeks. In addition, many Laravel apps start as a monolith, evolve to a distributed monolith and then finally transition to lightweight microservices, highly decoupled and deployed independently.
With orchestration, the business process is captured explicitly in a single place.
But the downside is that the logic for the business process, what we care most about, is now scattered throughout the system. Our business process has become an emergent property of the system, no longer explicit.
