Here we have defined a PredictionIO CloudFormation stack that you can deploy a functional, fully distributed PredictionIO cluster in minutes.</p><h3 id='instances' class='header-anchors'>Instances</h3><p>The PredictionIO CloudFormation stack creates two types of instance: <strong>compute an
 d storage</strong>. By default, the stack will launch <strong>1 compute Instance and 3 Storage instances</strong>.</p><p>The compute instance <em>(ComputeInstance)</em> acts as Spark master. You can launch extra compute instances <em>(ComputeInstanceExtra)</em> by updating the stack. The storage instances <em>(StorageInstance)</em> form the core of the HDFS, ZooKeeper quorum, and HBase storage. Extra storage instances <em>(StorageInstanceExtra)</em> can be added to the cluster by updating the stack. They cannot be removed once they are spinned up.</p><p>PredictionIO Event Server will be launched on all storage instances.</p><h3 id='networking' class='header-anchors'>Networking</h3><p>The stack will automatically create a VPC and a subnet with an Internet gateway. All cluster instances will be launched inside this subnet using a single security group that enables all TCP communications among all instances within the same group. All compute instances (including those that are launched
  after stack creation) will receive public IPs. All core storage instances will receive public Elastic IPs.</p><h2 id='step-by-step' class='header-anchors'>Step-by-Step</h2><p>First, you need to have an active Amazon Web Services account with permissions to use the following services:</p> <ul> <li>Auto Scaling</li> <li>CloudFormation</li> <li>EC2</li> <li>VPC</li> </ul> <h3 id='subscribe-to-predictionio-cluster' class='header-anchors'>Subscribe to PredictionIO Cluster</h3><p>Before you can start using PredictionIO CloudFormation template, you will need to subscribe to PredictionIO Cluster AMI through AWS Marketplace.

You should see everything functional.</p></li> <li><p>Run through the section <strong>Create a Sample App</strong> as described. The installation directory of PredictionIO is <code>/opt/PredictionIO</code>.</p></li> <li><p>Run through the section <strong>Collecting Data</strong> as described, except that you will be connecting to the Event Server at the master core storage instance. Assuming the private IP of the master core storage instance is <code>10.0.0.123</code>, add <code>--url http://10.0.0.123:7070</code> to the <code>import_eventserver.py</code> command.</p></li> <li><p>Copy HBase configuration to the engine template directory. The full path of the configuration file is <code>/opt/hbase-0.98.9-hadoop2/conf/hbase-site.xml</code
 >. (This step will not be required in future releases.)</p></li> <li><p>Run through the section <strong>Deploy the Engine as a Service</strong> up to the subsection <strong>Training</strong>. Assuming the private DNS name of the master compute instance is <code>ip-10-0-0-234.ec2.internal</code>, add <code>-- --master spark://ip-10-0-0-234.ec2.internal:7077</code> after the <code>pio train</code> command. This will send the training to the compute cluster instead of the local machine. The Spark master URL must match exactly the one shown on its web UI. Repeat the same steps for subsection <strong>Deploying</strong>, which will create an Engine Server backed by the compute cluster.</p></li> </ol> <h2 id='scaling-the-cluster' class='header-anchors'>Scaling the Cluster</h2><p>As your data size and/or audience grow, you can scale your cluster to handle more workload or decrease turnaround time.
