Alibaba Cloud - I think they still give a one-year free trial on its cloud hosting plan, so that you can try it. After that, you can continue using Alibaba Cloud by paying them, it’s cheap, only if you want to…
There are other companies too, who use to give a year trial…
Amazon AWS - is not completely free but in past they also use to give a one-year free trial. You have to pay after one year.
