Recently, I asked Colt Engine to help us with the MaxScale Beta Testing process. They agreed to do this, but they had to find the best way to test a new environment, with MaxScale on top and with as little impact as possible on their datacenter. The traditional approach would be to create as many virtual machines as needed and configure them for the designed test environment. This is a valid approach, but it requires some time to setup and the unnecessary use of resources. Instead, they decided to use an “Application Container”; they decided to use Docker.
