Like in other business domains this is a "make or buy" decision.

To decide of course you need enough data about the situation at hand:

- initial costs

- keep system running costs

- other pro/con items like "availability" (e.g. you can use a local server even if there is issues with your companies internet access) that can be prioritized and rationalized with methods like the cost-utility analysis or the cost-benefit analysis

I think it is hard to give general advice on what to do in such cases.
