Containerize all the things with Ubuntu Core 20
The key difference between regular Ubuntu and Ubuntu Core is the underlying architecture of the system. Traditional Linux distributions rely mostly on traditional package systems-deb, in Ubuntu's case-while Ubuntu Core relies almost entirely on Canonical's relatively new snap package format.
Ubuntu Core also gets a full 10 years of support from Canonical rather than the five years traditional Ubuntu LTS releases get. But it's a bit more difficult to get started with, since you need an Ubuntu SSO account to even log in to a new Ubuntu Core installation in the first place.
