Orchestration vs. Choreography

In this section

• BPMN (Business Process Model and Notation): Standard for Modeling Business Processes in Orchestration
  BPMN is a graphical representation for specifying business processes in business process modeling. It is a standard used to model the detailed sequence of processes and information flow within an organization. BPMN provides a standardized method to define and document the full sequence of interactions and decisions involved in a business process, focusing on the orchestration aspect of process management.
• Choreography Patterns: Using Event-Driven Coordination
  Choreography Patterns leverage event-driven architectures using patterns like Publish-Subscribe and Event Streaming for service coordination and integration in distributed systems.
• Choreography: Decentralized Service Interaction Design Pattern
  Choreography is a design pattern that promotes a decentralized service interaction model where services react autonomously to events without a central orchestrator.
• Compensating Transactions: Handling Failures in Business Processes
  Compensating Transactions is a design pattern used to handle failures in business processes by executing reverse transactions or operations. This pattern is crucial in enterprise systems where long-running and distributed transactions are common, ensuring consistency without traditional atomic transactions.
• Conditional Execution: Making Decisions at Runtime to Direct the Flow of a Process
  Conditional Execution is a design pattern in which decisions are made at runtime to direct the flow of a process. This pattern is crucial in orchestrating processes within enterprise integration by allowing dynamic responses to varying conditions and states. Through functional programming with Clojure, Conditional Execution provides a robust mechanism for managing control flow in complex systems.
• Data Sharing in Choreography: Allowing Services to Share Data Directly
  A design pattern guiding the direct data sharing between services within a distributed system, promoting efficiency and scalability by foregoing a central orchestrator.
• Dynamic Orchestration: Adjusting Process Flow Based on Real-Time Conditions or Data
  Dynamic Orchestration is an integration pattern where the process flow is adjusted dynamically based on real-time conditions or data, providing flexibility and adaptability in enterprise systems.

• Orchestration: Centralized Control in Service Interactions
  Orchestration refers to centralized control over the flow and interactions of services within an enterprise. It differs from choreography by managing how services communicate and interact through a central orchestrator.
• Parallel Execution: Running Multiple Tasks Simultaneously
  Parallel Execution is a design pattern that enables running multiple services or tasks concurrently within an orchestrated workflow, leveraging the full potential of distributed and cloud computing environments.
• Policy-Based Orchestration: Defining Rules and Policies to Guide Process Execution
  Policy-Based Orchestration focuses on defining rules and policies for guiding the execution of business processes. It allows for flexible integration solutions by separating decision logic from process logic, facilitating dynamic adjustments and governance of workflow execution.
• Process Monitoring: Tracking the Status and Performance of Orchestrated Processes
  Process Monitoring is a critical design pattern that ensures the tracking and performance assessment of orchestrated processes. This pattern plays a crucial role in maintaining the health and efficiency of business operations by efficiently dealing with orchestration and choreography mechanisms in enterprise environments.
• Process Optimization: Orchestration vs. Choreography in Enterprise Integration
  Improving the efficiency and effectiveness of orchestrated processes through process optimization techniques, comparing orchestration and choreography in enterprise integration.
• Process Orchestration: Centralized Workflow Management
  Process Orchestration in enterprise systems involves using a central orchestrator to manage the execution of services, providing a more controlled and coordinated workflow environment.
• Saga Pattern: Managing Long-Running Transactions with a Series of Local Transactions
  The Saga Pattern is a design strategy used to manage and coordinate long-running transactions across multiple microservices through a series of smaller, isolated local transactions.
