Others have answered this in a more complete and technical way, but when I end up talking with scientists about containers, I tend to reverse the question - *everyone* asks, "What are containers?" and "What is the cloud?", and since they're big topics with some nuance, I reverse it and just describe what those areas let us do for the applications in question. In our case, some of our applications have complicated build environments, requiring specific versions of libraries, compilers, etc. If we can containerize them, the end-user (a scientist) doesn't need to worry about all the complexity. They can focus on their science, while we provide software, via a container, that 'just works'. At least in theory. ;-) - Brian >
