Building Services with WSO2 Microservices framework for Java and WSO2 AS

  1. 1. Building Services with WSO2 Microservices Framework for Java and WSO2 Application Server Kasun Gajasinghe & Kishanthan Thangarajah WSO2
  2. 2. Agenda • Introduction to Microservices Architecture • Introduction to WSO2 MSF4J – Hands-on Sessions • Introduction to Kubernetes/Docker • Demonstrating MSF4J deployment with Kubernetes • Introduction to WSO2 Application Server – Hands-on Session
  3. 3. Microservices Architecture A method of developing software applications as a suite of independently deployable, small, modular services in which each service runs a unique process and communicates through a well-defined, lightweight mechanism to serve a business goal.
  4. 4. Microservices http://martinfowler.com/articles/microservices.html
  5. 5. Inner & Outer Architecture http://blogs.gartner.com/gary-olliffe/2015/01/30/microservices-guts-on-the-outside/
  6. 6. WSO2 Microservices Framework for Java (MSF4J) • Lightweight & fast runtime • Use Java annotations as a way of defining microservices APIs as well as metrics • Support well known & widely used methods such as JAX-RS annotations • Provide simple ways to develop & deploy microservices • Built-in Metrics & Analytics APIs with out-of-the-box integration with WSO2 Data Analytics Server (DAS) • To be used in the WSO2 platform as a way of replacing all admin services as well as defining other microservices for inter-component interactions
  7. 7. MSF4J Implementation • Based on the new WSO2 Carbon 5.0 kernel • Transport is based on Netty 4.0 • Supports streaming • High performance • 5MB pack size • Starts within 300ms • ~25MB memory consumption for the framework
  8. 8. MSF4J Performance Comparison
  9. 9. MSF4J Memory Consumption Comparison
  10. 10. Core Features of MSF4J • Quick & simple development model using simple annotations • Lightweight & high performance • Custom interceptors • OAuth based security • Metrics gathering & publishing • Streaming input & streaming output support • WSO2 DevStudio based tooling for generating microservices projects starting from a Swagger API definition • Comprehensive samples demonstrating how to develop microservices application
  11. 11. MSF4J Flow & Thread Model
  12. 12. Developer Experience & Programming Model
  13. 13. Development Model • Maven Archetype • IDE/Build Classpath (msf4j-all.jar) • Tooling (Swagger -> Code)
  14. 14. Maven pom.xml
  15. 15. Maven Archetype mvn archetype:generate -DarchetypeGroupId=org.wso2.msf4j -DarchetypeArtifactId=msf4j-microservice -DarchetypeVersion=1.0.0 -DgroupId=org.example -DartifactId=myservice -Dversion=1.0.0-SNAPSHOT -Dpackage=org.example.service

  20. 20. Types of Deployment • Standalone, Self contained jar files • OS / Container images
  21. 21. Analytics & Monitoring Supports annotations • Timed – measures execution • Metered – measures rate of events • Counted – counts the total invocations • HTTPMonitored – monitors HTTP requests
  22. 22. Analytics & Monitoring
  23. 23. Service Metrics - Console Output
  24. 24. Security • Security is done via a central server issuing JWT or OAuth tokens. • The OAuth2SecurityInterceptor verifies the token before accessing the resources.
  25. 25. MSF4J Hands-on Sessions
  26. 26. Hello World! 1. Build the sample - wso2msf4j-dist-1.0.0 /samples/helloworld mvn clean install 2. Run the sample java -jar helloworld-*.jar 3. Test the sample curl http://localhost:8080/hello/wso2
  27. 27. Generate a sample with Maven archetype mvn archetype:generate - DarchetypeGroupId=org.wso2.msf4j - DarchetypeArtifactId=msf4j-microservice -DarchetypeVersion=1.0.0
  28. 28. Hands-on - Write a StudentService • API - – GET /student/getAll - get all students – GET /student/get/{id} - get student with {id} – POST /add - add a student • Intercept requests • Monitoring
  29. 29. Service class annotations • JAX-RS HTTP resource methods - @GET @POST @PUT @DELETE • Content-negotiation - @Produces @Consumes • Service lifecycle - @PreDestroy @PostDestroy
  30. 30. HTTP Monitoring with Data Analytics Server 1. Refer the sample - wso2msf4j-1.0.0/samples/metrics- httpmon/metrics-httpmon-fatjar
  31. 31. Production Deployment with Kubernetes and Docker
