Typical Use Cases
▪ A system of systems: connect
multiple systems together.
▪ Better consumer experience with
connected data and business
processes.
▪ Digitize legacy systems: mediate
legacy with modern architecture
paradigms.
▪ Hybrid integration by taking on-
premise data and processes into
the cloud and back.
A Hybrid Integration Platform

5. WSO2 Enterprise Integrator
• Enterprise Service Bus (ESB)
• Data Services Server (DSS)
• Business Process Server (BPS)
• Message Broker (MB)
• Business Rules Server (BRS)
• Microservices Framework for Java (MSF4J)

6. Why 6.x?
• WSO2 ESB was the most widely used integration product from WSO2
• WSO2 ESB is at the core of EI
• The latest WSO2 ESB release was 5.0
• This is the evolution of WSO2 ESB and includes all the integration
technology from WSO2 in a single downloadable pack

7. Runtimes
• Integration (short lived integrations)
• Business Process (Long running integrations)
• Message Broker
• MSF4J (https://github.com/wso2/msf4j)
• Analytics

8. Service Integration
& Messaging
is based on Open Standards & Integration Patterns

10. ▪ EIPs are enabled using
individual building blocks
called Mediators
▪ There are many types of
out of box mediators that
provide common
capabilities such as
filtering, aggregating,
switching etc.
▪ These mediators are
available via the tooling
component to build the
various EIPs
▪ EIPs cover a wide spectrum of common integration scenarios
▪ 100% coverage for all published EIPs with source configs

15. Service Hosting
Host services and microservices

16. Hosting Java Apps and Services
● Use Tomcat or any other App Server for hosting standard apps
● Tomcat + CXF for JAXWS or JAXRS services
● MSF4J for lightweight, high performance microservices

17. Migration
Moving from olders products to WSO2 EI

18. New Directory Structure

19. Migration Strategy - should I now?
EI 6.x is an integrated and improved packaging of WSO2 ESB 5.0, DSS 3.5,
BPS 3.6
If you are already using these products, you can:
● Continue using these products
● All fixes will be available as WUM updates
● Next major upgrade will be to Ballerina (ballerinalang.org) based Enterprise
Integrator

20. No, I still want to migrate to EI 6.1!
● Migration is possible
● Deployment artifacts are the same
o Synapse config
o DSS files
o BPEL artifacts
● Location of the deployment artifacts and conf files have changed
● This will require some minor changes to your deployment automation

21. Documentation
● Documents from ESB, DSS, BPS & MB have been merged
o https://docs.wso2.com/display/EI600/WSO2+Enterprise+Integrato
r+Documentation
● Comprehensive Quick Start Guide which touches on all components of
EI

22. Demo
Enterprise Integrator in Action

23. Enterprise Integrator 6.1.0 Demo
1. Retrieve doctor records from dataservice
2. Data services performs the CRUD
3. Respond to the client with doctor records
4. Medical appointment reservation request
5. Call relevant hospital services
6. Store message in MB for payment process
7. Message processor sequentially picks the
messages from message store and injects to
the payment processing sequence.
8. Invoking payment backend service
9. Send appointment status email
10. Initiate cancellation process.

24. Some of the EI functionalites used for this demo
● Exposing a database as a service
● Hosting services on MSF4J
● Routing Requests Based on Message Content
● Storing and Forwarding Messages
● Using the Gmail Connector
● Managing a business process

25. Configurations
● Hosting services on MSF4J
● Setting up message broker with EI
● Configuring data publishing
● Setting up mail connector
● Configuring Activiti.xml in business process

26. Exposing a database as a service
● Creating data service
● Exposing as a rest API
● Rest API Invocation

27. Storing and Forwarding Messages
● Stores the messages to a JMS message store
● The back-end service is invoked by a message processor, which picks
stored messages in the JMS message store.
