There are a ton of small time complaining blogs about all the clouds, but practically none of them are at a scale where it really matters anyway. A recent one was about how clouds should be dumb pipes, but the blog forgot about the 30 FTE you'd be hiring just to maintain your 'own' IAM, API and on-demand CRUD of generic resources (like compute, storage, networking and higher level resources like databases, object stores, queues, buffers, pubsub). And then they also forgot about the benefit of scale they would never be able to compare with as a single customer vs. a multinational specialised company with practically every possible service scenario under the sun... Once you are beyond about 200K with enough in-house dedication you can start thinking about higher level abstractions that make you less bound to a single cloud or less bound to a single implementation (which can still be on a single cloud vendor's offering). You'd end up going that way anyway because at scale some facilities start to need adjustments to keep up with demand, like the creation and lifecycle management of object stores; you really can't be manually or bare-API managing those anymore when you have a ton of them. At that point you make processes, policies and automation a thing and if you implement them with some abstraction in mind it suddenly can be made to work everywhere... this is also where the bulk cost and ROI comes in; say you have your internal adaption in place for S3, adding B2 or R2 is really not that hard. Bam, object egress solved (For non-IAM scenarios; signed URLS would still work tho). But maintaining and owning this when you aren't big enough is just a drag your customers (internal and external) aren't going to profit from, and you really should be spending your time and resources elsewhere. Because you should probably focus on your business first, on what your customers want (so you can sell more in a commercial setting), and then on optimising your processes at which point you might be getting to the size where your increase in vertical integration starts making sense.
