Cloud Computing Concepts:
Cloud servers are virtual servers which is
primarily an IaaS (Infrastructure as a service) cloud
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
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 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 server.
Features and Benefits of cloud servers
scalability: Extra resource can be accessed as and when required
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
to the number of available servers, if there are problems with some, the
resource will be shifted so that clients are unaffected.
