    29. 29. Founded in 2008,<br />Initially PaaS for Ruby.<br />Now supports Ruby, Node.js, Clojure, Python, and Scala.<br />Since September 2011 supports Java.<br />
    30. 30. What do we need?<br />Maven 3.0<br />JDK 1.6+<br />Heroku account<br />Installed Herokuenv. (inc.Git, Foreman)<br />Java application built on Maven.<br />
    31. 31. Next step<br />Configure application using pom.xml<br />Configure Procfileto declare how you want your application executed<br />web: java $JAVA_OPTS -jar target/dependency/jetty-runner.jar --port $PORT target/*.war<br />Run locally. “foreman start”<br />“gitadd .”<br />git commit -m “Are you sure???“<br />heroku create --stack cedar<br />git push heroku master<br />
    32. 32. Heroku is awesome <br />Built-for-Deployment Applications<br />Version Control is the Central Distribution Mechanism.<br />No Need to Externalize Configuration From Your Code<br />Deployment is a Highly Automated Pipeline Process<br />How do Applications use JEE APIs Without a Container?<br />Servlets and JSPs by Tomcat or Jetty.<br />JSF and other rendering frameworks by Mojarra or MyFaces<br />Mail services by SendGrid.<br />JDBC to connect to HerokuPostgres service or Amazon RDS<br />Hibernate or DataNucleus JPA to provide an ORM persistence <br />
    33. 33. Heroku is awesome <br />Deployment “gitpush herokumaster”<br />Start/Stop/Restart “herokurestart”<br />Deployment of Changes<br />Clustering (scaling) “heroku scale web=2 worker=4”<br />Load-balancing<br />Logging<br />
    34. 34. Something else about heroku<br />Dyno???<br />Isolation by subvirtualization technologies<br />One request at a time<br />512MB of memory<br />Web/worker dynos.<br />$0.05 per hour<br />Payment<br />Dynos<br />Database<br />Add-ons<br />
    35. 35. THANK YOU!<br />Database.com SDK<br />HEROKU for Java<br />by Alex Kruk<br />Skype: alexandrkruk<br />Email: alex.kruk@parx.com<br />
