Nowadays there a plenty of cloud-providers out there offering a bunch of services. If you want to try these or even use them regulary for free, I have something for you.
I will just cover VMs here, but feel free to look also at other services.
Offers some services 12 months free of charge. I will not go into detail because sadly this is not ALWAYS free. But have a look at https://aws.amazon.com/free/
