This slide deck gives an introduction to WSO2 Enterprise Integrator and why you should choose its packaged capabilities to solve a typical integration requirement as opposed to using multiple integration products. Watch webinar here: https://wso2.com/library/webinars/2018/09/wso2-enterprise-integrator-101/

2. Half of All Development Will Be Integration
Consider that today’s 50mn endpoints will soon grow to 1T

3. WSO2 Enterprise Integrator
WSO2 Enterprise Integrator (WSO2 EI) is an open source, hybrid
integration platform, which allows developers quick, iterative integration of
any application, data, or system.

4. A Hybrid Integration Platform
Connectivity / Integration: anything-to-anything

Data
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

5. From ESB to Enterprise
Integrator

6. • A combination of products is often required to address complex
integration problems
• Difficulty in identifying the correct combinations of products to be
used
• Complexity in maintenance and support
Integration Solutions Observations

7. Integration Platform Components
● WSO2 Enterprise Integrator encapsulates the functionality from
○ WSO2 Enterprise Service Bus (ESB)
○ WSO2 Data Services Server (DSS)
○ WSO2 Business Process Server (BPS)
○ WSO2 Message Broker (MB)
○ Microservices Framework for Java (MSF4J)
○ Micro Integrator
○ Eclipse IDE-based Tooling
○ Analytics

8. ● Integrator - Systems and data integration
● Business Process - Long running processes and workflows with
human interactions
● Message Broker - Standard compliant, portable, interoperable
message broker
● Microservices - Host microservices implemented using Java and
MSF4J
● Micro Integrator - Container-friendly lightweight version of integrator
● Analytics - Analyze data flowing through WSO2 Enterprise Integrator

12. Enterprise Integration Patterns (EIP)
Best Practices in Mediation and Integration
• 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
● https://docs.wso2.com/display/IntegrationPatterns

13. Connectors to Connect The Enterprise
The Connector Store
● To connect and integrate with common systems & platforms
● More than 170+ enterprise connectors
● No additional cost - download and install
https://store.wso2.com/store/assets/esbconnector/list
● Can build your own connector easily

Using web APIs

20. Graphical Editor for Mediation Flow and
Data Mapping
WSO2 EI Tooling
• Provides graphical and source view editing of integration artifacts
• Eclipse-based

21. Debugging Mediation
• Packaging / archiving artifacts for deployment
• Debugging support on mediation flows
• Provide editor support for BPS, DSS, registry, etc. artifacts.
• New dashboard with sample templates

22. Integration Analytics
Dashboards for Transaction Analytics and Monitoring
Overall setup
• Overall Throughput (in TPS)
• Overall Message Count
APIs, proxies, endpoints specific
• Request Count
• Message Count
• Message Latency
• Explore Messages
• Explore Message Flows

23. Supporting Standards
23

24. Integration Standards Supported
Open Interoperability
• HTTP(S)
• JMS-1.1/ 2.0, AMQP, MQ, MSMQ
• WebSockets
• VFS
• TCP, UDP
• FIX, HL7
• BPMN 2.0, WS-BPEL 2.0
• JSON, SOAP-1.1 / 2.0
• XSLT, XPath
• JDBC, NO-SQL, CSV, OData-v4
• UT, OAuth, SAML, XACML,
WS-Sec
• and more ….

25. Deployment Choices
25

26. ● Deployment for Availability
Recommendation is a minimum of 2
active nodes for a high availability
deployment
● Deployment for Scalability
TPS based scaling (EI benchmarks at
2000-4000 TPS each with 200+
concurrency and 10ms latency. EI
support a pass through of 1000+
concurrency with 0.5 ms latency with
non-blocking transport)
Elastic scaling via AWS/cloud platforms
like K8S/Docker

27. Deployment and Scalability - Integrator
● Clustering
○ Stateless clustering - No shared state, HTTP
○ Stateful clustering with leader election: For polling transports, tasks,
and caching, throttling
○ Artifacts synchronizing - push model or shared file system/rsync
model
Stateless Stateful
