DB2 Big Data and Cloud webinar on Dec 6
DB2 Big Data and Cloud webinar on Dec 6
Leveraging Clouds for Small and Big Data
Date: Dec 6, 2011 Time: 12:30 PM - 2:00 PM (Eastern Time) Hosted By: Rav Ahuja (IBM) Presented By: Leon Katsnelson (IBM), Uri Budnik (RightScale), Robert Thomas (IBM)
Many experts agree that Cloud Computing has now matured past the initial hype phase and that organizations large and small have started to derive real benefits by placing applications and data on Clouds. In this webinar we will discuss how to leverage Cloud Computing for managing data and gaining insights from big data. We will cover various Cloud options (public, private, and hybrid) available for managing data in the Cloud with IBM DB2 database server as well as for deriving value from big data using IBM BigInsights hadoop-based platform. We will also show you how to be up and running in as little as a few minutes using free editions of DB2 and BigInsights. You ought to find this session useful regardless of whether you are a beginner or expert in cloud computing or big data.
To learn more please Join Uri Budnik (RightScale), Leon Katsnelson (IBM), and Rav Ahuja (IBM) on Tuesday December 6th, 2011 at 12:30 PM Eastern.
Presentation slides will be available for download from ibm.com/db2/labchats shortly before the webcast starts.

Deploy Golang Web Application to Heroku cloud Platform
Deploy Golang Web Application to Heroku cloud Platform
Here I will provide you the details to deploy simple golang web application on Heroku.
I hope reader of this post has already installed Golang package and have basic knowledge about golang and basic skill about git not mandatory.
I am using go1.6 version on Linux-Ubuntu machine for this post.
sujin@sujin:~$ lsb_release -d
Description: Ubuntu 14.04.4 LTS
sujin@sujin:~$ go version
go version go1.6 linux/amd64
Setup Go directory structure and set GOPATH env variable. add GOPATH/bin to PATH env variable.
set working directory in GOPATH
sujin@sujin:~$ echo $GOPATH
/home/sujin/godir/work
Register in heroku website to get free account https://signup.heroku.com/?c=70130000001x9jFAAQ
install heroku tool belt
Pull the HerokuTest project from git
Now push your application to git heroku master

Setup Go directory structure and set GOPATH env variable. add GOPATH/bin to PATH env variable.
set working directory in GOPATH
sujin@sujin:~$ echo $GOPATH
/home/sujin/godir/work
create a simple web app in golang. For this example i create a folder called HerokuTest, inside a file called HerokuTest.go that contain program below
package main
import (
"fmt"
"net/http"
"os"
)
func homeHandler(w http.ResponseWriter, r *http.Request) {
fmt.Fprintf(w, " Hello World From Golang on Heroku")
}
func main() {
http.HandleFunc("/", homeHandler)
fmt.Println("Server Listening...")
err := http.ListenAndServe(":"+os.Getenv("PORT"), nil)
if err != nil {
panic("ListenAndServe")
}
}
Compile and test the program locally
sujin@sujin:~/godir/work/src/blog/HerokuTest$ go build
sujin@sujin:~/godir/work/src/blog/HerokuTest$ ls
HerokuTest HerokuTest.go
sujin@sujin:~/godir/work/src/blog/HerokuTest$ PORT=7070 HerokuTest
Server Listening...
Go to the url http://127.0.0.1:7070/ from web browser it will print Hello World From Golang on Heroku in web page.
We should manage dependency package using Godep
install godep
go get github.com/kr/godep
save all golang dependencies
sujin@sujin:~/godir/work/src/blog/HerokuTest$ godep savesujin@sujin:~/godir/work/src/blog/HerokuTest$ ls Godeps HerokuTest HerokuTest.go
We should create Procfile to tell Heroku which command to execute on web
sujin@sujin:~/godir/work/src/blog/HerokuTest$ echo web: HerokTest > Procfile
Now its time to configure git for the project.
git init
git add .
git git commit -m "Heroku Test Project Initial Commit"
git remote add origin https://github.com/sujinsr/HerokuTest.git
git push origin master
Register in heroku website to get free account https://signup.heroku.com/?c=70130000001x9jFAAQ
install heroku tool belt
sujin@sujin:~/godir/work/src/blog$ heroku login
Enter your Heroku credentials.
Email: sujinsr@gmail.com
Password (typing will be hidden):
Logged in as sujinsr@gmail.com
Pull the HerokuTest project from git
go get github.com/sujinsr/HerokuTest/...
Move to project directory and create heroku instance for your application
sujin@sujin:~/godir/work/src/github.com/sujinsr/HerokuTest$ heroku create heroku-test-app-blog -b https://github.com/kr/heroku-buildpack-go.git

Deploy spring mvc application in cloud
After login to the cloud computing instance, run either the "uname -a" or "cat /etc/redhat-release" to discuss the linux os version of the instance.
Follows the following link to install and run tomcat server:
http://tecadmin.net/install-tomcat-8-on-centos-rhel-and-ubuntu
If your spring mvc uses MySQL for database backend, follows the following link to install and run mysql:
http://www.rackspace.com/knowledge_center/article/installing-mysql-server-on-centos
(for centos 7): https://devops.profitbricks.com/tutorials/install-mysql-on-centos-7/
Once you have the environment setup, follow the link below to deploy your Spring MVC framework into the cloud computing instance:
