Thank you for all your responses here - I am red-faced with shame to realise I'd for years completely ignored exactly what containers are and associated terms such as 'Heroku' or 'Kubernetes' I'd simply assumed they were curious alien creatures, completely irrelevant to me! After a long journey down various rabbit holes last night, where I at points got quite excited by the idea of leveraging Heroku with perhaps a soupçon of Cloudflare in the background or AWS' myriad of services, I ended up back where I've always been, and think I'll stick with what I know for my upcoming project. However, I think this'd be a great way to dabble in things I really don't have any famiiarity with (eg. Ruby), so I'll have a play yet. Thanks, all!
