Many developers are in need of complex development- and test environments for different projects with customers. The ideal situation would be to have them running in a sandbox. With help of the Cloud and VMs it’s possible to create those sandbox-environments but administration, configuration and maintenance cost a lot of time and money. With a combination of Vagrant & Puppet it’s possible to create and configure those environments “on the fly”. Anytime, anywhere and above all reproducible. The Talk shows how fast you can create and configure a sandbox for a Java environment including an Application Server and a database with the help of those tools.
