Let's do some basic math.

Let's say that I rent two redundant dedicated servers that : - are each used at about 80% - are each equivalent of about 100 cloudlets - cost each $ 60 / month

If I want to switch to Jelastic, that's 14 x 100 x 2 x 0.8 = $ 2240 per month (gross simplification), against 2 x 80 = $ 160 per month + maintenance.

So if maintenance is < 2k€ for me, that's a no deal. In US a freelance sysadmin will cost more (?), but in my country, no. Too bad :)
