SOA design patterns are reusable solutions to a commonly occurring SOA design problems. 

Some common SOA patterns include: 

Enterprise Service Bus: A tool that fosters service communication by providing reliable messaging, message queuing, data transformations and service broker functionality. 

File Gateway: A file gateway is placed between a service and legacy flat file. The gateway acts as a mediator and can perform data transformations. 

Event Driven Messaging: The service notifies its consumers of relevant events with messages. 

Service Callback: A service requires that consumers communicate with it asynchronously. Consumers provide a callback address to which the service can send response messages. 

Service Grid – Service state is stored on a grid of services that support replication and redundancy.
