Just a bit more than 5 years ago Docker, a containerization project, was launched. The developers happily moved their applications running on a VM to Docker containers and felt happier even despite the bugs they ran into.

It made not only the app development easier, but offers more flexibility and opportunities for scaling to the projects.
