I've found that in our SaaS environment there is very little coordination between the sysadmin, NW, Application Admin, and security services. It becomes an extreme headache when implementing integrations between internal systems & the SaaS hosted application. The engineering ownership we THOUGHT we could rely on the vendor to do ... Well, not so much. It is the exception that an implementation goes smoothly.

If a circuit goes down or there is a downtime in your network that connects you to the outside world, all of your SaaS apps are up, but in reachable from within your facilities.

I am asking about any generic system in general and not particularly the AR System, when used On Premise vs SaaS.. which is why I prefixed the subject of this email as “Slightly OT”.. I’d like to know about the hidden advantages and disadvantages that are not so apparent other than the obvious. The obvious advantages and disadvantages of SaaS I would percept are: Advantages: 1) No onsite administration – lowers cost of ownership 2) You are almost always up to date on versions etc. 3) You do not risk downtime when a system is upgraded, or during system maintenance, or bug fixes. The vendor usually has a faster planned route to rollback. Disadvantages: 1) No onsite administration – reduces flexibility in some areas of customization. 2) Your data resides off premise so it poses some kind of security risk 3) You are vendor/manufacturer dependant – the manufacturer goes out of business, so would your solution. And the obvious advantages and disadvantages of an on premise solution I would percept are: Advantages: 1) Onsite administration – You could do what you want, when you want, how you want to the system as you please with no rules whatsoever apart from system limitations 2) You can choose when to update if at all or stay on whatever version works for you as long as you wish to. Lowers user training costs to a certain extent. 3) Your data is as secure as you want it to be. 4) Your solution life lasts beyond the manufacturers – if they go out of business, you can continue to run their solutions for a while until you have a better solution. Disadvantages: 1) Onsite administration – You usually face higher maintenance and running costs. 2) You risk downtime during maintenance or upgrades or bug fixes even with a good rollback strategy. Any other advantages and disadvantages to the two strategies that I may have not listed here?
