That’s a bit of an oversimplification, but was mostly true during cloud technology’s infancy.
Modern clouds provide elastic compute resources and can offer platform, operating systems, and applications as a service.
Regardless of how “elastic”, it is still someone else’s server, under someone else’s control, at someone else’s location and in someone else’s building
Exactly. I try to explain that all those things—platform, operating systems, applications, communications—are commodities.
You don’t own your own power plant, even if you use 100s of kilowatts of electricity a day. Let those who do produce power concentrate on doing so and at a massive scales; we all buy some as we use it.
