About the Presenters  ๏  Kasun Indrasiri

๏  SoUware  Architect,  WSO2  ESB  

4

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

Glimpse of Modern Enterprises  ๏  Disparate Systems, Services, Protocols

๏  Diverse and dynamic business requirements

๏  No single vendor/solution

๏  On premise/Cloud solutions

6

Point to Point/Spaghetti Integration  ๏  Scalability, maintainability, troubleshooting

nightmares.

7

ESB as the Integration Bus  ๏  Conquering integration nightmares with WSO2

ESB

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 9

๏  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

10

Integrate anything with everything..

๏  Enterprise Integration Patterns

§  De facto standard for enterprise integration

๏  WSO2 ESB offers 100% coverage of EIPs

11

Conventional Integration Patterns

๏  Stateless Service Orchestration – ESB

§  Service Channing – call mediator or receive sequence

§  Clone/Aggregate – clone, aggregate mediators

§  Split/Aggregate - iterate, aggregate mediators

12

Service Orchestration

๏  A stateless service chaining scenario realized with the application of multiple EIPs

13

Service Orchestration

๏  Stateful Service Orchestration – BPS

§  Stateful orchestration of number of services

§  Long running processes

§  Compensation handling/Rollback

§  Human Tasks

14

Service Orchestration

๏  Service Orchestration – BPS + ESB

§  ESB handles the connectivity between disparate systems and services

§  BPS handles the orchestration

15

Service Orchestration

๏  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

๏  WSO2 ESB – Comprehensive REST support

§  HTTP Endpoint – Nouns and Verbs

§  Payload Factory/Script Mediator – Data Formats

17

RESTful Integration

๏  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

๏  HTTP Endpoint and JSON Payload Factory

19

RESTful Integration in action

๏  Integrating SAP and non-SAP systems

๏  IDOC and BAPI based integration

20

SAP Integration

๏  Make messages persistent so that they are not lost even if the messaging system crash

§  Message stores and processors

21

Guaranteed Delivery with WSO2 MB

๏  API Façade with WSO2 ESB and WSO2 API Manager

22

API Façade Pattern

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

23

Connectors

๏  Salesforce + Google Spread Sheet - Opportunity Management
