Re: Hey, you, get on to my cloud
You forget the "electricity" has no unique properties, my amperes do just the same as yours.
With IT it is the underlying problems of:
(1) Data protection. How many providers have client-side encryption by default so they (and foreign gov) can't spy on you?
(2) Bandwidth. If your task is computing-heavy, then you have a real problem with (1) (can't secure it remotely as it is on someone's VM so can be imaged while unencrypted) but not much with I/O bandwidth. However, if you work on a lot of data-heavy tasks then your ISP link will become a serious bottle neck and could run up a mighty bill.
(3) Redundancy. Oh sure, the likes of Amazon, MS, etc, have lots of hardware redundancy and similar, but also they may have a single point of failure (e.g. certificate recently in MS' case) and your ISP is likely to be the same. While your own building is also at risk, given the number of failure points for the ISP(s) between you and them it is much worse. And paying serious money for another provider is no guarantee it won't share the same fibre trunking, etc. (Actually, a local JCB mistake is more likely than large scale ISP outage).
Some may argue without an Internet like, your business is stuffed, but not always. Quite a lot of jobs (CAD, video editing, writing up reports, business planning, general HR duties, etc) can be done for a while with no external link at all.
(4) Lock-in. Once your balls are in the vice, they can turn the screws on you and what can you do? How do you migrate TB/PB of data from one cloud to another? Is that data really open, or locked in to some software they had you use? Have you actually tested such a migration to see if and how painful it can be?
Sadly the article is probably right, as a lot of "youf" seem to care little about privacy or the long-term implications of their choices.
