That is true, but it is also very much an understatement of just how miserable every step of the OC experience is.
I was once forced by a customer to endure the torture that is OC, and the only thing that saved me was when Oracle's terrible management software just deleted our entire account and deployment one weekend. Gone without a trace, could not even log in anymore. Luckily, that was enough to persuade the client to move to Azure.
I've had previous clients whos entire account with production servers just get nuked without even so much as a curtsey email and OCI support WILL NOT HELP.
To be fair, I have been testing Oracle Cloud Infrastructure(OCI) on a paid account for about 2 years now and actively monitor server hosting forums.
During that time I have had no "abnormal" problems with paid production account.
However, it is well known that Oracle accidentally nuked free/trial accounts early on, and again recently accidental nuked free/trial accounts reserved public IPs. However, I know of no such events for paid accounts, and paid accounts on OCI should be production ready quality in my experience.
On the other hand support really is somewhat bad, but support is free and the cloud costs are much less than AWS, while having better products than similar priced cloud products such as Lnode, Vultr, Digital ocean.
You can bet your bottom dollar I trial things on lower tiers, and much later on I may very well take the things I learned into production. My production budget isn't as big as some, but its still a tidy 6 figure sum each year just for cloud hosted services, with no licences or wages in that figure. If my trial on your platform goes tips up without notice, I'm going to likely conclude you're not a particularly safe place for my production stack for whatever it is I'm working on. You should also count on me telling my contemporaries about my experience too.
The basic idea is simple, "give developers free personal resources so they might be inclined to start using your cloud for work related thing". Instead, the "free account" is basically just a guided tour on OCI incompetence before it boots you out onto the street.
On the surface they have given it some thought with setting up the system perfectly with the whole, "if your account is free you can never be charged thing" but they can't seem to stomach people actually using their "free account".
please don't.
I have nothing but the worst experiences with Oracle Cloud. Granted, I was always a little biased against Oracle as a company; but I have a friend working on OCI and assumed that since what I needed was really basic it would be fine.
It really wasn't, it was awful, confusing and opaquely and egregiously expensive.
