You can't guarantee that, even with high amounts of redundancy, there's still the possibility of a failure. You can implement your own software and systems to copy your data to other servers (with other providers, preferably in completely different countries to minimize the risk of downtime), and then have traffic automatically fail over to one of those servers, Even so, don't guarantee that things will never go down - Things could go wrong with your software, and there's also the possibility that all of your servers could go down at the same time (unlikely, but it's a possibility).

Hi ,
I have a VPS that I use as mqtt broker for a my app that use mqtt.
Now I must provide this service to my clients and I must grant that the server doesn't go out never.
How I can do this?
