PaaS

Platform as a Service is a category of infrastructure products that makes life easier for developers: instead of managing infrastructure on their own, the vendor takes care of things like installing the right software, managing upgrades, and connecting databases. For a fee, of course.

The OG PaaS was Heroku, who won the hearts and minds of developers before they got acquired (perhaps sadly) by Salesforce in 2010 and all but destroyed.
