Docker is a relatively new technology, but it is based on solid underpinnings of the Linux Kernel. It can provision instances in a fraction of the time versus a traditional virtual machine. This makes it a great candidate for development teams to create consistent test benches for their developers. To set up your own disposable Docker environments bring a laptop and make your development a pleasurable experience.
