Cloud servers can be configured to provide levels of performance, security and control similar to those of a dedicated server.
But instead of being hosted on physical hardware that’s solely dedicated to you, they reside on a shared “virtualized” environment that’s managed by your cloud hosting provider.
You benefit from the economies of scale of sharing hardware with other customers.
With cloud servers, you only pay for the exact amount of server space used, and have the benefit of infinite flexibility.
You can scale resources up or down resources depending on demand, and avoid paying for idle infrastructure costs when demand is low.
