Yes, good point -- Arturia should monitor their own infrastructure so they know when there is a problem. There are even free and open source solutions like nagios and nice WebUI management panel add-ons that work with it that are also free but very well-featured like check_mk. With the free/open-source solutions, the quality of what you'll get out of them is what you are willing to put into them (time wise). There are also outfits you can hire to come sit it all up for you if you have the cash to burn.
You can also set up with external monitoring service providers to monitor your public-facing systems from multiple locations on the internet and alert your IT teams when there is an issue.
Let me put it this way -- there are enough options for software, providers, and levels of service in this space that the bean counters and IT team members will have plenty to argue about. It is really more of a statement about the last hot dog stand I worked at as a UNIX systems engineer, but the arguing over cheaper vs more expensive options (vs. what the developers liked, vs. what this or that engineer wanted to work on, etc.) went on for months every time somebody decided it was time to change the setup.
At the end of the day investing in a good monitoring infrastructure is worth it though. You look a lot better to your customers when you find out about problems as soon as they start because your monitoring infrastructure is telling you something is wrong, rather than finding out days later from your customers. By then it is affecting your reputation...
