佈建一個 J2EE Application Developer 所需的環境需要多少時間 ?

Acquire HW,SWx days

Configure Server1 hours

Configure Network2 hours

Install Database3 hours

Install J2EE Server5 hours

Install MQ Server4 hours

Configure server.xml6 hours

7 hours

Ready for developer8 hours

而且這可能不是最壞狀況… .實際花的時間可能更久


如果可以透過雲端技術直接開 Virtual Machine, 那我們就可以省去 2+ 小時的時間 .

3


如果可以透過雲端上有裝好的 Database, WebServer, MQ Server, 那我們就可以省去 5 + 小時的時間 .

4


那雲端有可能幫我把在 J2EE Server 中設定 Database, MQ… 及驗證環境的 2 小時自動做掉嗎 ?

5


有的 , IBM 數位創新平台 Bluemix 中的 Java Liberty 搭配 MQ Lite , SQL DB 服務 ,可以自動配置 server.xml 讓 Configuration 一次到位 , 省下更多的時間專心處理業務邏輯的問題

6


So …. IBM 創新平台 Bluemix 是什麼 ?

What is Java Liberty?

The Liberty profile is a highly composable, fast-to-start, dynamic application server runtime environment. It is part of IBM WebSphere Application Server v8.5.5. The buildpack provides a complete runtime environment for running Java EE 7 and OSGi applications on top of Liberty profile. It supports popular frameworks like Spring and includes the IBM JRE. WebSphere Liberty enables rapid application development that is well suited to the cloud.

11


Liberty features supported in Bluemix

12

和傳統 Websperhe(Full Profile) 不同 , Websphere Liberty 只載入指定的 jar, 而不是整套J2EE

How it works?

Sign-on/login Bluemix in the http://www.bluemix.net

點選 Java DB Web Starter 即可快速配置 Java +SQL DB 環境

16


設定網站名稱

17

取好 host name , 按 Create


就是這麼簡單 2 分鐘後 , 你就有一個帶有 internet 網址的 Liberty Server

18

你可以用以下三種工具寫 code:•Eclipse•Command Line•Web IDE (also know as Bluemix DeOps, Eclipse Orion)

並且可以讓Bluemix 幫你配置一組 Git Project


配置好的 Liberty Server 如下 , 預設使用 1 instance ,512M 的 RAM,開發人員可以自己 Scale up, Scale out, 不用再求 OP 協助

19


檢視目前的 server.xml

20

Server.xml 中的 DB2 設定自動配了


Which services in Bluemix can be auto-configured to Java Liberty?

ClearDB MySQL Database MySQL ElephantSQL PostgreSQL Cloudant® NoSQL Database MongoLab dashDB™ Data Cache Session Cache MQ Light Monitoring and Analytics Auto-Scaling Single Sign On New Relic

21

Auto Configure to:

Auto-Configuration 其實就是 Application Re-staging 時 , Java Liberty 針對其所認識的服務自動做Binding


不只設定配好了 , 還有 Java access DB 的範例

22

我不要範例 , 我要飯粒

點選 ADD GIT


Bluemix DevOps –IDE, Git, Auto-Build, Auto-Deploy with Sample Source Code

23


試 Run 一下 Sample

24

填一筆資料


查看 DB 內容

25

由此進入 DB 管理介面


查看 DB 內容

26

Yes, 範例沒造假

28


build.xml 在 Bluemix Build 時會用到

29


manifest.xml 會影響 runtime 的 hostname, 及設定

30


網頁程式呼叫 api/todolist 做呈現

31


來做點小修改測試一下變更及佈署

32

把 Java DB Web Starter 改成…


切到 Git 畫面準備交付

33

確認修改後按 push 觸發上版


Build & Deploy 成功

34


查看 Compile Log

35


查看 Deploy Log

36


改版成功

37

更改前為 Java DB Web Starter


We also support deploy to Docker !!

38

只要多寫個dockerfile

如果在 Bluemix 上只是寫 Java access DB 就太可惜了
