Server for Spot Pricing Details and Error Reporting.

• Objective: Cost efficient provisioning on the cloud
• Key Results:
  • Model of cost including static and dynamic parameters such as cloud price model, resources and network topology. This model should cover at least a few public cloud providers such as Amazon Ec2, Google Compute Engine and ..
  • A recommendation system for estimating optimum configurations.
  • Visualising configuration-cost options on the map in the Web Client.
• Motivation: Optimised cost model for renting resources on cloud is to the interest of both companies and research institutions. Different cloud providers have different price list while they don't provide exactly the same resources/latency and so on

• Payara 4.1
• JavaEE 7
• Rest Service(Jersey)
• J2ee Batch procesing
• Maven web application - JSF
• JPA - mySql
• Jclouds

1. Once payara is installed, make sure it can access MySQL Connector/J. To do this, copy the MySQL Connector/J jar file to the payara/lib directory. For example, copy mysql-connector-java-5.1.30-bin.jar to C:\payara-install-path\payara\lib. Restart the payara Application Server.
2. Creating a Jdbc Connection Pool and Jdbc resource used as datasource in persistence.xml. You can find all these configurations in glassfish-resources.xml. tutorial.

• You can also use payara admin console to load this xml file and generate resource.
• Start Your payara server admin console: usually http://localhost:4848
• On your left navigate to [Resources]
• Use [Add Resources Button] to load xml file
• restart the server

3. An empty databse called servicerecommender should be created in mysql manually.
4. increase packet size in mysql -> /etc/mysql/my.cnf under [mysqld] max_allowed_packet= 128M

JavaEE Batch does not support mysql when deployed on glassfish so we use payara

1. Start Your payara server admin console: usually http://localhost:4848
2. On your left navigate to [Server] > [batch] > [configuration]
3. choose right datasource and database (schema) name. Required data source will be created after first time deploying the application.
4. restrart the server

Disable implicit CDI in payara permennatly, so beans.xml will be required for CDI. (Jclouds CDI issues)

$ asadmin set configs.config.server-config.cdi-service.enable-implicit-cdi=false

Should be stored in a file in specified path for the server to find them. This is how the file looks like.

[default]
aws_access_key_id = ........
aws_secret_access_key = .........

http://Server:8080/CloudServiceRecommender/api/

1. Start Your payara server admin console: usually http://localhost:4848
2. On your left navigate to [Configurations] > [server-config] / [default-config]> [Jvm settings] > [Jvm options] > -Xmx2048m , -XX:MaxPermSize=512m

1. Start Your payara server admin console: usually http://localhost:4848
2. On your left navigate to [Configurations] > [server-config] > [EJB Container]
3. Then click the TAB up top [EJB Timer Service]
4. Then fill out Timer Datasource: with your JDBC Resource eg. [jdbc/mysql]
