> I would recommend people to use AWS monitoring

Use a monitoring service to monitor the provider of the monitoring service? Wouldn't it be better to use a monitoring service hosted on a totally different provider?

I'm not even sure running your own monitoring is sufficient in this case. Sure it's useful to have, but when something goes wrong, the first thing I want to know is if it's us or them. If it's us, I/the team scramble to fix it in a panicked frenzy. If it's them (the cloud provider), and they acknowledge it early, even a simple "we're investigating an issue with X", we can at least take some comfort from the fact that it's out of our hands.

If we just don't know the cause, we assume it's us and jump into panicked frenzy mode. Panicked frenzy days are the worst days of my life, especially if it's discovered that it was all in vain.
