Developing a SaaS product based on completely proprietary stack that you can't even host yourself is VERY dangerous!!! Just yesterday there was a report that twitter bought a company and immediately closed their API access to all customers.

What will you do, if Amazon decide to close your AWS account for some reason? What if they discontinue one of the services you use?

Here is a huge list of products discontinued by Google as example: https://en.wikipedia.org/wiki/List_of_Google_products#Discon...

Most of the stuff in GCP won't be closed like the list as they are used by enterprise customers (Or at least, there will be proper notice, migration path etc). I agree that at the end of the day you have little control over the infrastructure, its impossible for a lot of companies to maintain them which is why they are going to cloud. If you are very worried, you can just use the VMs (EC2 or GCP's VMs etc) and not use other services.

I think the other more important path mentioned would be: "what happens in case of a ban/restriction?". Not with AWS, but we've previously had accounts locked/closed "accidentally" - thankfully they were non-mission critical.
