5. Agenda
๏ Commonly used integration patterns with WSO2
Middleware Platform
๏ Inspired from real world scenarios
๏ Integration Ecosystems - Go beyond building a
set of integration silos
5

6. Glimpse of Modern Enterprises
๏ Disparate Systems, Services, Protocols
๏ Diverse and dynamic business requirements
๏ No single vendor/solution
๏ On premise/Cloud solutions
6

7. Point to Point/Spaghetti Integration
๏ Scalability, maintainability, troubleshooting
nightmares.

8. ESB as the Integration Bus
๏ Conquering integration nightmares with WSO2
ESB

9. Introducing WSO2 ESB
๏ A light weight, high performance ESB
๏ Comprehensive REST, SOAP, WS-* support
๏ 100% compliant with all EIPs (Enterprise
Integration Patterns)
๏ Connectors (Salesforce, Twilio and many more)
๏ SAP, FIX, HL7 - Domain specific solutions
๏ Zero Code/Configuration driven
๏ Extensible and Scalable

10. ๏ Conventional Integration Patterns
๏ API Façade Pattern
๏ Hybrid Integration Patterns
๏ Store and Forward
๏ High-availability and Failover
๏ Security Patterns
๏ Patterns Related to Monitoring and Complex Event
Processing

Integrate anything with everything..

11. ๏ Enterprise Integration Patterns
§ De facto standard for enterprise integration
๏ WSO2 ESB offers 100% coverage of EIPs
11
Conventional Integration Patterns

12. ๏ Stateless Service Orchestration – ESB
§ Service Channing – call mediator or receive sequence
§ Clone/Aggregate – clone, aggregate mediators
§ Split/Aggregate - iterate, aggregate mediators
12
Service Orchestration

13. ๏ A stateless service chaining scenario realized with
the application of multiple EIPs
13
Service Orchestration

14. ๏ Stateful Service Orchestration – BPS
§ Stateful orchestration of number of services
§ Long running processes
§ Compensation handling/Rollback
§ Human Tasks
14
Service Orchestration

15. ๏ Service Orchestration – BPS + ESB
§ ESB handles the connectivity between disparate systems and
services
§ BPS handles the orchestration
15
Service Orchestration

16. ๏ Service Orchestration – ESB or BPS ?
§ How to select the perfect fit?
• Stateful vs stateless
• Complexity of the orchestration
• Long running processes
• Learning curve of BPEL
16
Service Orchestration

17. ๏ WSO2 ESB – Comprehensive REST support
§ HTTP Endpoint – Nouns and Verbs
§ Payload Factory/Script Mediator – Data Formats
17
RESTful Integration

18. ๏ JSON is increasingly getting popular
๏ Native JSON support with WSO2 ESB 4.8
§ No canonicalization (i.e: No conversion back and forth
JSON->SOAP->JSON)
§ JSON Path for JSON Content Based Routing
§ Support all kinds of transformations (JSON->JSON,
JSON<->XML)
18
Comprehensive JSON Support

19. ๏ HTTP Endpoint and JSON Payload Factory

RESTful Integration in action

20. ๏ Integrating SAP and non-SAP systems
๏ IDOC and BAPI based integration

SAP Integration

21. ๏ Make messages persistent so that they are not lost
even if the messaging system crash
§ Message stores and processors

22. ๏ API Façade with WSO2 ESB and WSO2 API Manager

API Façade Pattern

23. ๏ A connector is a ready made and convenient tool to
reach publicly available web API s.
