The point isn't to serve the volume that SalesForce has, the point is to serve yourself.

If you have experience enough to prevent downtime or to handle it when it happens, then perhaps that is better than risking that to someone else.

the 20 hours of downtime was probably BECAUSE of the amount of data/customers to handle. whereas if there is 1 customer, recovering isn't nearly as difficult or time consuming.

I think his point is that when comparing running SalesForce on the cloud for every users SalesForce has, vs running SalesForce locally for your users, there will a lot less challenge to keep it running locally than on the cloud.

> I seriously doubt the services you've managed have even served a fraction of the data and customers SalesForce has.

So what?

If your business is built around a system and that system goes down, would you rather that system serve billions of customers and go down for 20 hours, or serve only you and go down for 20 minutes?
