I think this article can be a little misleading. Sure, with cloud tech you can easily spool up more instances. And yes, it is great to not have to worry about configuring a load balancer (I guess). But just because adding more instances sort of fixes a problem doesn't mean it is a good thing to do. Not "having to do calculations" is a very bad attitude. You should know where the bottle necks are, and if adding instances is actually necessary or just some scotch tape. Bad architecture and coding can bite you in ways that adding hardware cannot fix.
