Jelastic is a Java hosting platform which can run and scale any Java application with no code changes required. It offers different application servers(Glassfish, Tomcat, Jetty)  and databases (MySQL, MariaDB, PostgreSQL and MongoDB) and even a NGINX  loadbalancer. With a view mouse clicks you can create and configure your Jelastic environment. If you think one server is not enough you can add a loadbalancer and multiple servers. And if you want secured access to you applications, just use the SSL on/off switch. If you would like to know more about creating a Jelastic environment and deploying a Java web application (for example Apache Roller) on it you can read more here.
