There are not a lot of those companies which are that big.

You also might not want to manage that many it experts for your infrastructure or you are not able to get them.

Also if your companies product is very technical, i would argue that those companies are much better equiped doing it by themselfs then others.

Nonetheless, it also doesn't need to be all or nothing. You can easily combine a MultiCloud approach.

Build only the stuff which is easy to build and costs a lot on cloud yourself. I would say Buildsystems or compute instances are good candidates.

Like i could imagine putting netflix authentication system on a cloud provider while doing the compute stuff in my own data center and building the CDN myself.

There may be reasons to go multicloud but ease isn’t one of them. You double your infra support overhead (or more likely, half its quality) and have a “least common denominator” experience.

The natural tendencies of large organizations is a diffusion of investment but the cheapest costs frequently come from a concentration of investment.

Bigger you are bigger the differences between teams and products and projects.

You can leverage the high quality network infrastructure from Google while using your own DC for Compute Heavy Load.

Use Azure for your Windows specific workloads.

Go with AliCloud in China.

You need to be big enough so that running it yourself is doable with a certain amount of quality. Which does imply many teams and workloads.

There are lots of entities that are big enough. Given that the cloud stacks change from time to time, you don't reduce your need for engineers and other SMEs -- in some cases you need more.

I would say as someone who supports lots and lots of apps that cloud services are usually financial winners in a SaaS perspective and in a rapid growth scenario. Nobody can deliver Exchange cheaper than Microsoft. My team stood up apps for covid related activity for 20-40% of the cost and more importantly type than services under our organizations control.

That said, for what I would call "base load" scenarios, in many scenarios it's exactly the opposite.
