Cloud Computing & Virtualization project - HillClimbing@Cloud

Install the following tools:

• Maven 3.x.x
• Java Development Kit 7 (JDK 7)

The project is organized in 3 modules:

• databaselib, a library that contains code to interact with DynamoDB.
• loadbalancer, which contains the code to run in the Load Balancer server.
• web-server, which contains the code to run in the Web server.

The first two modules use maven, and the last already has all the files compiled.

Execute the following command:

./create_archives.sh

Place the .dat and .png files from the dataset in web-server/datasets.

Run create_archives.sh script.

Create an AWS ec2 server instance, with port 8000 open for TCP, and java 7 installed. Download the AWS Java SDK , and unzip it in the home directory.

Copy the web-server.zip archive to the instance, and unzip it:

scp -i CNV-AWS.pem ./web-server.zip ec2-user@<IP_ADDRESS>:~

Append the following, to etc/rc.d/rc.local (change the aws package version, if needed):

export CLASSPATH="$CLASSPATH:/home/ec2-user/web-server/pt/ulisboa/tecnico/cnv/server:/home/ec2-user/web-server:/home/ec2-user/db-lib:/home/ec2-user/aws-java-sdk-1.11.546/lib/aws-java-sdk-1.11.546.jar:/home/ec2-user/aws-java-sdk-1.11.546/third-party/lib/*:."
export _JAVA_OPTIONS="-XX:-UseSplitVerifier "$_JAVA_OPTIONS
cd /home/ec2-user/web-server
java WebServer

Create the ~/.aws folder and put the following files in it:

• webserver.properties (example)

  server-region=us-east-1
  

• credentials (example)

  [default]
  
  aws_access_key_id=<ACCESS_KEY>
  
  aws_secret_access_key=<SECRET_ACCESS_KEY>
  

Create an image of this instance.

Run create_archives.sh script (if you haven't already).

Create an AWS ec2 server instance, with port 8080 open for TCP, and java 7 installed. Download the AWS Java SDK , and unzip it in the home directory.

Copy the lb-bin.zip archive to the instance, and unzip it:

scp -i CNV-AWS.pem ./lb-bin.zip ec2-user@<IP_ADDRESS>:~

Run the following (change the aws package version, if needed):

export CLASSPATH=$CLASSPATH:/home/ec2-user/db-lib:/home/ec2-user/aws-java-sdk-1.11.538/lib/aws-java-sdk-1.11.538.jar:/home/ec2-user/aws-java-sdk-1.11.538/third-party/lib/*:.

Create the ~/.aws folder and put the following files in it:

• webserver.properties (example)

  server-region=us-east-1
  image-id=ami-0e38c8854738d9646
  key-name=CNV-lab-AWS
  sec-group=CNV-ssh+http
  instace-type=t2.micro
  subnet-id=subnet-ac760882
  

• credentials (example)

  [default]
  
  aws_access_key_id=<ACCESS_KEY>
  
  aws_secret_access_key=<SECRET_ACCESS_KEY>
  

To startup the LoadBalancer run the following command inside lb-bin/:

java pt.ulisboa.tecnico.cnv.loadbalancer.LoadBalancerApplication
