Using any cloud only makes sense if a) you don't know how to setup things yourself and b) your project is so big, that salaries for ops would be higher than cloud cost.

Also, be careful with b) since you still need people that know how to do stuff, otherwise, you will experience either data breach or long downtimes.

What most people won't admit when recommending cloud is that, yes, cloud has all sorts of utility built into, like data replication, backups, scaling, etc. but things go wrong in cloud as well and if you don't have good knowledge of how things work, you will be in for a wild ride.

IMO, it is much better to learn setup things yourself, even in non-optimized way and have some knowledge on what to do when stuff begins to break.
