Introduction

CloudStore is an open-source e-commerce web application developed following the functional requirements defined by the TPC-W standard, and it's goal is to be used for the analysis of cloud characteristics of systems, such as capacity, scalability, elasticity and efficiency. It was developed as a Showcase application to validate the CloudScale tools that were developed during that project.

The application was developed in Java using the Spring framework and running on a Tomcat web application server, while using a MySQL database. Static files and images needs to be generated with ImgGen tool, but a default database dump and load generation scripts are available in order to start testing a deployment in a very short time.

Different IaaS, PaaS, Storages and Architectures can be tested with little one little changes to the code.

Database

CloudStore is using MySQL database. Database can be generated by running src/main/java/eu/cloudscale/showcase/generate/Generate.java file:

$ cd src/main/java/eu/cloudscale/showcase/generate/
$ javac Generate.java
$ java Generate mysql

This takes a long time and it's slow. We recommend you to import SQL dump into your MySQL database.

Running

For running CloudStore on your computer you will need Tomcat and MySQL database installed. You can also import and run CloudStore from Eclipse IDE. Before you can run CloudStore on Tomcat you will need to compile it into .war archive. Before compiling the CloudStore edit some config files.

Configs

With config files you tell CloudStore where it can find the images and how to connect to database.

src/main/resources/app.properties

In this file set the url for CSS, JavaScript and image files:

eu.cloudscale.files.url.css - URL to the folder with CSS files

eu.cloudscale.files.url.img - URL to the folder with image files

eu.cloudscale.files.url.js - URL to the folder with JavaScript files

src/main/resources/database/database.aws.hibernate.properties

In this file configure the MySQL database:

jdbc.driverClassName - Set to com.mysql.jdbc.ReplicationDriver if you want to use master-slave MySQL setup. Otherwise set it to com.mysql.jdbc.Driver value.

jdbc.url - Connection URL to the host and database. Format is jdbc:mysql://<host>/<database_name>.

Note: If you want to use master-slave MySQL setup use jdbc:mysql:replication:// format, otherwise jdbc:mysql://.

jdbc.username - Username to connect to database

jdbc.password - Password for the user to connect to database

jdbc.hibernate.dialect - Hibernate dialect

Compiling

CloudStore is a Maven project so you will have to install the Maven tool.

When you installed Maven you can compile CloudStore into war archive with executing the following command:

$ mvn clean install

from directory where the pom.xml file is located.

Installing

Copy target/showcase-1.0.0-BUILD-SNAPSHOT.war to Tomcat.

Using ImgGen tool

Open file populate_images and edit:

$NUM_ITEMS - How many items/books are in database (default: 10000)

$DEST_DIR - Directory name where to save generated images

$GEN_CMD - Path to tpcwIMG program for generating the images (default: ImgFiles/tpcwIMG)

Now run command:

$ ./populate_images

Copy the directory with images to somewhere publicly available.
