These platforms offer cloud-based environments with pre-installed packages and resources, making them highly suitable for teaching and training purposes. In addition, if you do not have a GPU or you are a macOS user without GPU or without the right GPU these cloud platforms serve as an excellent alternative. Or maybe you lost connection to your Windows/Linux remote machines and you really want to reconstruct a tomographic dataset.</p>
