• ○

  a service, acting as a publisher, issues event notification messages to an event management program that is responsible for broadcasting the messages

• ○

  a service consumer, acting as a subscriber, can selectively subscribe to specific events

• ○

  an intermediate event management program enters the role of subscriber when accepting event subscriptions

• ○

  upon receiving a message associated with an event that a service consumer subscribed to, the service consumer enters the publisher role

  The Compensating Service Transaction pattern is often applied by calling one or more "undo" operations provided as service capabilities of the services participating in a composition.

• ○

  A compensating service transaction must be designed independently and without knowledge of the technical service contracts belonging to the composition members.

• ○

  Compensating logic is generally expressed in its own process definition and separated from the overall service composition logic.

• ○

  The Compensating Service Transaction pattern is one of the core patterns that comprise the Enterprise Service Bus compound pattern.

• ○

  Using the Reliable Messaging pattern can improve the quality of messaging-based communication.

• ○

  The Reliable Messaging pattern is applied to databases, not services.

• ○

  The Reliable Messaging pattern is one of the patterns that can be associated with the Enterprise Service Bus compound pattern.

• ○

  The Reliable Messaging pattern is always applied together with the Atomic Service Transaction pattern.

• ○

  redundantly deployed services

• ○

  service agents that perform load-balanced access to services that are not redundantly deployed

• ○

  compositions that compose redundantly deployed services

• ○

  A service agent intercepts and stores a message from the service consumer. The service agent then returns an acknowledgement back to the service consumer. Next, the service agent forwards the message to the service and when it receives an acknowledgement back from the service, it deletes the message.

• ○

  A service agent intercepts and stores a message from the service consumer. The service agent then forwards the message to the service. Next, the service agent receives an acknowledgement from the service, which it returns to the service consumer. Finally, the service agent deletes the message and related acknowledgements.

• ○

  The service consumer stores the message and forwards it to a service agent, which issues an acknowledgement back to the service consumer. The service agent then forwards the message to the service and when it receives an acknowledgement from the service, the service agent informs the service consumer so that it can delete the message and the acknowledgement.

• ○

  The application of the Rules Centralization pattern centralizes the governance of business rules so that they can be modified and evolved from a single location.
  

• ○

  The application of the Rules Centralization pattern reduces redundancy by centralizing common business rules-related logic that would normally be distributed across multiple services.
  

• ○

  The application of the Rules Centralization pattern results in centralized business rules that can be applied at runtime.
  

• ○

  The application of the Rules Centralization pattern can lead to a decrease in autonomy because it can introduce the need for an additional service to be part of service compositions.
