It's clear that AWS, Azure and GCP are the most used and popular cloud providers around the world. We can add Alibaba Cloud to this list because they have a high demand in the market.

I know some other options less popular that we can use for some scenarios:

Cloudinary: Used for video and image (media content)
Oracle Cloud: Databases and storage
Netlify: Web services and applications
IBM Cloud: Compute, integration and storage

What of these alternative cloud providers do you use?
What other cloud providers do you know, and how was your experience?
