Cloud sales: Not new
How many users are really saving by using these services instead of their own?
The issue though isn't money. If it's not profitable it's not sustainable sales price. If it is very profitable, then many people can do it cheaper themselves. It's not like buying pay TV which if you think you need it, you can't make your own.
The real issue is should people be using the cloud at all, other than temporary files or ad hoc collaboration of non-critical nature.
Core Business functions shouldn't be outsourced.
What strategy is there if you lose internet connection, so called cloud provider goes down?
Privacy? Security? Backups?
The cloud is a hype and buzz world. The services are as old as shared computers. It's not a new business but a 50+ year old one that for 20 years has been migrating from expensive secure leased lines to insecure and unknown up time internet connections to access it.
