Yesterday I came across the article with review of Jelastic cloud. The author explains this service in the following way: "It’s kind of like WHM/cPanel but hosted on a cloud and can also manage server clusters rather than just one server, and integrate many other cloud services (storage, CDN, DNS, etc)" https://wpjohnny.com/jelastic-cloud-platform-review

Seems as a good suit for you to start with. They have control panel and automation of some infrastructure management processes, so you can get started even without profound technical cloud expertise and dive deeper eventually.
