A cloud server is a virtual server that runs in a cloud computing environment. It is a type of Infrastructure-as-a-Service (IaaS) that provides users with access to computing resources on demand, without the need to purchase and maintain their own physical servers. Cloud servers are typically billed on a pay-as-you-go basis, so users only pay for the resources they use.
Cloud servers offer a number of advantages over traditional physical servers. They are more scalable, so users can easily add or remove resources as needed. They are also more reliable, as they are typically hosted in multiple data centers, which helps to protect against outages. Additionally, cloud servers are more secure, as they are managed by a team of experts who are responsible for keeping the environment up to date with the latest security patches.
