Can you trust a cloud provider for HA?

We have seen a massive increase in the “real world” dependency on digital services in the last few years. This process will probably continue in the future, and we are not ready for it. In the same few years, we have seen a lot of cases where digital services went offline or got hacked. In a society that relies more and more on digital services, we can not afford such services not to be available or secure.
