Java/Spring과 Node.js의공존

1. Java/Spring과 Node.js의 공존 Java/Spring 전성시대에 Node.js가 살아남는 법 Dongsu Jang <iolothebard at gmail dot com>

2. TOC • BEGIN • AS-IS • TO-BE • VS • CODE • END

3. BEGIN JUST FOR FUN

4. 개발자여, 불가능한 꿈을 꾸어라 • java8, tomcat8, spring-boot, spring-cloud, jpa… • mongodb, cassandra, couchbase, elasticsearch… • python, ruby, scala, rust, clojure, julia… • docker, kubernetes, mesos, microservices… • nginx, redis, play framework, akka, spark, node.js, django, flask… • angular, react, EcmaScript6… • IE8 없는 세상…

5. 그러나, 리얼리스트가 되라 • 현실은 자바 천국… • 스프링 전성 시대… • 봄날은 생각보다 오래 가더라… • “관리가능”한 아키텍쳐의 무거움 • 배포할 줄 아는 마지막 개발자가 퇴사 했어요 OTL • 지금 서비스 하는 버전이 svn 에 있는 거 보다 더 최신인데요 -_-; • 롤백할께요 ㅠ,.ㅠ • 서버 늘려야겠죠? 구매 요청할께요 ^^; • IE8 테스트할 PC가 없어요? XP요~ 그래도… 재밌는 거 해보고 싶어요!

6. AS-IS AS GOOD AS IT GETS

7. AS-IS • Java 5.x/6.x/7.x… with Tomcat 5.x/6.x/7.x… • Apache Web Server with mod_jk/ jk2/webapp… • Spring Framework with Spring- WebMVC/Struts… • Template Engine: JSP/Velocity/ Freemark… • DAO: MyBatis/Hibernate/JDBC… • Cache: EHCache/OSCache/Map… • RDBMS: Oracle/MySQL…

8. AS-IS tomcatapache webapp (war) MySQL tomcat … mod_jk apache … webapp (war) mod_jk MySQL AJPHTTP

9. AS-IS Spring Framework with Spring-WebMvc/Struts… JVM Template Engine JSP/Velocity/Freemarker… DAO JDBC/MyBatis/Hibernate… Cache EHCache/OSCache/Map… Tomcat Servlet Container Model View Controller

10. TO-BE STAY HUNGRY STAY FOOLISH

11. TO-BE • Node.js • Express • Thrift • Redis • React • 원래 있던 거…

12. TO-BE tomcatapache webapp (war) MySQL tomcat … mod_jk apache … webapp (war)mod_jk MySQL node.js API server + @ redis pm2 nginx React Server React Client node.js … thrift AJPHTTP + @ + @

13. TO-BE java Thrift Server (thrift/swift/nifty) Thrift Client (node-thrift) node.js RESTful API Server Isomorphic Rendering Server 원래 있던 거… (war) Single Page Webapp browser express react browerify, babel, … react
