Yes, perfectly doable, but the expertise and time needed to do it (without fatal mistakes) and keep it running 365 days a year is non-negligible. Doing this by unpaid volunteers is more than challenging.
Cooking isn't hard either but I still go to restaurants, and don't go around laughing at patrons telling them that they never bothered to learn how to cook if they are there.
Next time you see someone paying for something you think it's easy to learn, that the "zeitgeist told them not to learn", go up to them and say what I quoted and you'll see real fast if it's condescending or not.
The difference in situations here is literally that on the one hand large corporations have spent money to market the idea that their services are essential because the alternative is incredibly difficult. On the other hand, McDonalds, KFC, Burger King, "Big Restaurant" etc have not spent large quantities of money trying to persuade the populace that cooking at home is incredibly difficult. It's possible to sell someone a convenience without also telling that person that it's the only real option and this is what the person you're replying to is highlighting.
It's not condescending, it's the reality of the situation. Yes in the examples you've described it would be condescending but in the situation we're actually talking about there are actually large numbers of people who genuinely believe (as a result of successful marketing campaigns) that the equivalent to cooking your own meals at home is incredibly dangerous, difficult, expensive and error prone.
They haven't because it's a ridiculous proposition. The same way cloud providers would be laughed out of the room if they tried to say the same thing and they didn't actually have a better product with trade-offs that are genuinely better for some use cases. The fact that you believe that everyone using cloud products is either too lazy to learn or has been fooled by marketing because they can't think for themselves, unlike you who see the light, is the condescending part. Mind you, on the face of overwhelming data showing most companies have, or are moving large parts of their infrastructure to the cloud, so everyone else are dummies either too lazy or too stupid to see what you can see.
I never said anyone was too lazy, just misinformed about the benefits, and it's a more far fetched statement to claim that marketing doesn't work than it is to state that it does work.
As evidenced by some people in this thread claiming that not using S3 would be basically impossible (despite a large number of popular distributions literally doing exactly that) there are clearly plenty of people who have fallen for the marketing.
Moreover, you're the one implying that falling for marketing is something only people who can't think for themselves do, that's also not what I'm saying. I think everyone is susceptible to marketing, and in this case, clearly a lot of intelligent people who are otherwise capable of thinking for themselves have fallen for this blindspot.
I think you are the one being condescending here.
“Assume good faith”[1]
In any case one does it professional IT done right is costly but cheaper than e.g. IT without offsite backup in case of a disaster.
Not sure about that. There appear to be just as many people in IT, it's just that they're not that technical anymore, mostly producing policy documents and pushing tickets around. The actual work is outsourced to the cloud, SaaS products and outside consultants (for duct taping the mishmash of SaaS products together). But that may be just my lacking understanding of my strange little part of the globe.
Things don't fail as much as they used to, at least not from using something mature as minio and of course hardware can fail as they do specifically spinning rust, which is non trivial to replace if you have hot-swap capable servers in the first place.
I don't possess any decade worth expertise in either minio or running this kind of setup so personally I believe you are exaggerating that this is even worth calling challenge at all.
But that's just my take :)
It’s so easy, after all.
Pretending to know how much work something is when it's not your area of expertise is a bit silly.
Actually, yes, it is easy, after all :)
