IKEA makes cheap, good enough furniture. Similar to Amazon's approach. You can't argue that either is not hitting a certain high quality bar when neither are striving for it.

It's so fascinating how diverse people's viewpoints are! My first experience of IKEA was that it was a confusing, frustrating, poorly laid out and inefficient labyrinth designed to get you lost, and also funnel you to the "hot dog" items that make them the majority of their profit. I've taken many of my parents and observed similarly people's parents and grandparents of friends get just as frustrated and confused at the layout. For god sakes, I just want to be able to walk in, go to the "kitchen decor" get what I need, and walk out. I don't want an "experience", but I digress.
IKEA is not attempting to sell the highest quality furniture in the world. They are attempting to sell furniture that is "good enough" at a great price. Have they succeeded? Their customers seem to have dollar-voted with resounding "yes".
On the other hand, I have all Ikea furniture and it's survived 3-4 moves and only gotten stronger - my last mover's hobby was repairing furniture and he fixed everything with his pile of spare parts.
I use it for some small businesses of mine but I wouldn't use it for a medium company. I would just get some servers from smaller provider in different data centers and deploy whatever I need.
AWS, was definitely the service that convinced everyone they needed the cloud. Most of the companies I've seen move to aws are just wasting money, don't need the scalability and are massively over-provisioned.
A few unicorns needs the cloud's powers to scale massively now - and, given how much it costs, they'll end up rewriting it anyway to save hundreds of millions a few years down the line.
That said, AWS is solid and best in class in many areas, and to paraphrase the old saying: "no one ever got fired for choosing AWS"
