Orchestration

Orchestration is more of a Service Oriented Architecture (SOA) approach where we handle interaction between various services in an SOA. When we say orchestration, we maintain one controller that is the orchestrator or the main coordinator of all the service interactions. This typically follows more of a request/response-type pattern where a mode of communication can be anything. For example, we can have one orchestrator in our shopping microservices that does the following tasks synchronously—first, take customer orders, then check the product, prepare a bill, and after successful payment, update the product inventory.
