If you want something that is marginally cheaper in some regards and doesn't have too much custom stuff to wrangle with (AWS has a lot of stuff like IAM, security groups etc. that can be annoying to manage/confusing), I'd personally recommend Digital Ocean (https://digitalocean.com). You may know them from the tech tutorials that they write online (topics such as 'how do I install a certain tool or stack?').
They offer a free trial (https://try.digitalocean.com/freetrialoffer), which lets you use better resources for a while (the only issue is that downgrading is challenging, same as AWS).
