In some examples disclosed herein, a lighter-weight virtualization is employed by using containers in place of the VMs 114 in the development environment 112. Example containers 114a are software constructs that run on top of a host operating system without the need for a hypervisor or a separate guest operating system. Unlike virtual machines, the containers 114a do not instantiate their own operating systems. Like virtual machines, the containers 114a are logically separate from one another. Numerous containers can run on a single computer, processor system and/or in the same development environment 112. Also like virtual machines, the containers 114a can execute instances of applications or programs (e.g., an example application 102a) separate from application/program instances executed by the other containers in the same development environment 112.
