Before containerization made it so easy to prepare images for virtualization, it was quite an art to prepare custom ISO images to boot from CD. Later these images were used to boot virtual machines from. In other words, ISO images were precursors of container images. It is so that I had a couple of unfortunate run-ins with the Windows Docker client. Even when not running any containers, the Windows memory manager would hand it as much memory as possible slowing…

Introduction After coming up with a recovery plan for the various components of your application, you should set up the backup system that is required to support it.
