- 5. WSO2 Enterprise Integrator Single integrated packaging of • ESB and DSS as a single runtime • Business Process Server • Message Broker • EI Analytics (primarily ESB analytics) • MSF4J • Micro Integrator (New..!) 5
- 6. Service Integration - Integrator Runtime A lightweight, high performance service bus • Comprehensive REST, SOAP, and WS-* support • SAP, FIX, and HL7 - Domain specific solutions • Configuration driven • Extensible and scalable • 100% coverage of all EIPs 6
- 7. Data Integration - Integrator Runtime Building service abstractions on top of disparate data sources SQL SOAP/REST/OData XML/JSON 7
- 8. Business Processes - BPS Runtime • Define and execute business processes - WS-BPEL 2.0, BPEL4WS 1.1, BPMN 2.0, long running stateful processes • Define workflows interacting with people - BPMN user tasks, WS-HumanTask 1.1, BPEL4People 1.1 • Graphical process modeling 8
- 9. Micro Integrator • Startup time reduced • Distribution size reduced • Supports all key features • Removed features that are not useful for MSA • Container-friendly 9
- 10. Micro Integrator vs Integrator Profile Integrator Micro Integrator Startup Time 40s 5s Distribution size 592 MB 224 MB Mediation (ESB) Features ✅ ✅ Data Integration Features ✅ ✅ Built-in Clustering ✅ ❌ Tooling ✅ ✅ Management Console ✅ ❌ Dep-Sync ✅ ❌ Multitenancy ✅ ❌ CAR Deployment ✅ ✅ Hot deployment ✅ ❌ 10
- 13. 13 Traditional Virtual Machines • Virtual machine represents a logical/software abstraction of a machine • Virtualization layer acts as an intermediary to the host machine to request resources • A virtual memory manager (VMM) is the tool that typically provides this virtualization layer • Run multiple operating systems on a single machine
- 14. 14 Challenges, Disadvantages of VMs • Overall efficiency of a virtualized machine does not match up to that of a physical machine. • Each VM runs not just a full copy of an operating system, but a virtual copy of all the hardware • Need to install tools/utilities in each environment
- 15. What are Containers? 15 https://sysadmincasts.com/episodes/31-introduction-to-docker
- 18. 18 What is Docker Compose ? • Compose is a tool for defining and running multi-container Docker applications. • With Compose, you use a YAML file to configure your application’s services. • With a single command, you create and start all the services • docker compose up --build • Compose works in all environments.
- 19. 19 Networking in Docker Compose • By default Compose sets up a single network for your app. • Each container for a service joins the default network and is both reachable by other containers on that network
- 20. Networking in Docker Compose Sample 20 version: '3' services: redis-server: image: 'redis' ei-server: restart: always build: ./ei ports: - "8290:8290" node-app: restart: always build: . ports: - "8081:8081" EI-server Client Docker-Compose node-app redis-server

- 24. 24 Building the Micro Integrator Docker Image ● Download the Enterprise Integrator latest release – https://wso2.com/integration/ • Create the micro integrator profile by running the profile-creator.sh – Removes the other profiles contained within enterprise integrator and generates a smaller packaging • We will use the Dockerfile shipped within the micro integrator to build the docker image
- 25. 25 Building the Micro Integrator Docker Image ● Dockerfile contains instructions to ○ use open jdk image with alpine linux ○ copy the micro integrator binary package ○ create user, role and configure permissions ○ copy any CAR files to deployment directory • Within the CAR file, we will refer to the docker-compose service name give for the microservice docker image to invoke the msf4j service <endpoint name="QueryDoctorEP" xmlns="http://ws.apache.org/ns/synapse"> <http method="get" uri-template="http://healthcareservice:9090/healthcare/{uri.var.category}"/> </endpoint>
