I have a couple of questions for writing a (computer science) scientific/technical paper about the recommended style to enumerate or give a list of things.

This is my current sample:

Sharing IoT platforms requires support for: (i.) isolated software execution; (ii.) controlled resource allocation; (iii.) easy deployment of applications; and (iv.) secure management of applications. 

Questions:

1. is ";" a good demarcation? I've seen it recommended somewhere, but most people just use ",".
2. Is roman numerals recommended? If I use numerals, should I always use numerals (so no listing somewhere with (ii.) and with (2.) somewhere else. Is the overall style of brackets and punctuation OK?
3. What to do with repeating terms? In (iii.) and (iv.) I have the need to specify it is "of applications" but I hate the repetition.
4. Does it matter that this listing is intended to be part of the abstract? Should I use a slightly different style there or not?

Those are the main questions. In addition, I dislike the use of the word 'easy' in a paper. It is a bit... I don't know, trivial? But I'm loathe to use 'accessible' or 'simplified'. Deploying apps has become easier is what I want to say, but easy sounds wrong. But that could be me.
