WordPress is famously available at wordpress.com as Software-as-a-Service. What should one do if one comes to the conclusion that this isn’t what you need? The two obvious solutions are one of the cloud providers and I should say I personally use one&one for various reasons.
AWS now offer WordPress in Lightsail? What DDOS protection is there? What site loss, system loss protection is there?
Azure have a WordPress custom VM machine to use. Again What DDOS protection is there and what component failure protection is there?
