Ubuntu Server delivers services reliably, predictably and economically. It is the perfect base on which to build your instances. Ubuntu is the world’s most popular Linux for cloud environments and is suitable for small to large-scale Linux operations. Ubuntu Server for Azure is designed by Canonical (the publishers of Ubuntu) and optimized for Azure. For more information, see Ubuntu on Azure.

Ubuntu is free and will always be, with the option to access additional security, management tools and technical support when you need it through additional commercial offerings from Canonical (for example Ubuntu Pro 22.04 LTS).
