- Cloud servers are virtual servers which are primarily an IaaS (Infrastructure as a service) cloud service model
- Cloud servers are logical servers which are built, hosted and delivered through a cloud computing platform over the internet. Cloud servers possess and exhibit similar capabilities and functionality to a typical server but are accessed remotely from a cloud service provider.
- There are mainly two types of cloud servers: Logical Servers and Physical Servers
- A cloud server is considered to be logical when it is delivered through server virtualization. In this delivery model, the physical server is logically distributed into two or more logical servers, each of which has a separate OS, user interface, and apps, although they share physical components from the underlying physical server.
- Also, the physical server is also accessed through the internet remotely, it isn’t shared or distributed. This is commonly known as a dedicated cloud server.
- Unlike dedicated servers, cloud servers can be run on a hypervisor. The role of a hypervisor is to control the capacity of operating systems so it is allocated where needed. With cloud hosting, there are multiple cloud servers which are available to each particular client.
- This allows computing resource to be dedicated to a particular client if and when it is necessary. When there is additional traffic the resources are scaled up and if one server fails, data will be extracted from other servers.
Features and Benefits of cloud servers
Flexibility and scalability: Extra resource can be accessed as and when required
Cost-effectiveness; whilst being available when needed, clients only pay for what they are using at a particular time
Ease of Set up: Cloud servers do not require much initial setup
Reliability: due to the number of available servers, if there are problems with some, the resource will be shifted so that clients are unaffected.
