Here we can see the flow chart first.
Both Heroku and OpenShift provides the above concept to help us deploy applications easily and no need to concerns the hardware and software that can save a lot of time and cost.
Let's see more detail features about Heroku and OpenShift with the table below:

|---|---|---|
| Deploy from source | Git + Maven | Git + Maven |
| Deploy from existing war | No | Yes |
| Container | Embedded Jetty or Tomcat | JBossAS 7.0 |
| Datebase | NoSql add-on, PostgreSQL | MySQL |
| For ZK application | Yes[1][2] | Yes[3][4] |
From the table above, we know that both Heroku and OpenShift are working well for ZK application
