My experience is that it is usually ok to setup these kind of services. Takes few days, interesting and fun work to get new stuff going and tuned. Problems arise with the operations. Nobody is confident with doing the updates since they happen so rarely. If system is critical, do you dare to do updates during business hours? Is there proper test system to practice updates? Is anybody prepared to handle recovery scenarios? Who is testing backups? How do you transfer the knowledge when people who originally built the system leave?
