A lot of us dont trust them. They want credit cards and justifications and an approval process that seems like it is one of their con-fusion Enterprise apps. It's a hit or a miss especially if you want a machine in a geography that's not in the same region as your CC.
They don’t ask you for credit card details for their Free Tier version. I know because I’ve had that for over a year now.
In fact, their free tier is designed such that you only use free services. If you want to use their paid tier, you need to explicitly upgrade. I like that because that means I’ll never run into any unexpected charges.
I had to give a CC even for the free tier. Not sure if it some dark pattern that I could have skipped and on gone on to the next step. I filled everything in, nothing really came out of it other than an email or so but account details never turned up.
I'm already abusing (not really of course, I'm within limits) of my Heroku free tier and I had something running on Openshift until they removed the free tier.
It is true, I've been using them for one and a half years now and only one time I got an email that my instance had a few minutes of downtime due to an HW failure.
You also need to meet with Larry in a dark alley and sign over your soul in perpetuity, but other than that it's a great service.
Edit: To the downvoters, have you ever been through an Oracle audit? I can tell you it's "bend you over and thoroughly check out your insides" invasive enough that I will literally never again willingly work with such a company.
Honestly, I'm just looking for something I can run Wireguard on to proxy my traffic. It doesn't matter if it's ARM or not, what really matters is the public IP (IPv6 would be super cool) and lots of bandwidth.
