If you want to learn CRM basics and not a specific system, SugarCRM is very popular and is free and open source. You can install it on a Linux VM quite easily. Or you can install it to a system like A Small Orange with a single click. Getting access to a common CRM to play with it would be pretty easy. Then you can say that you have deployed it as well.
Azure has an out of the box SugarCRM in the Web App gallery 🙂
