Difference between Cloud and Server

Key Difference: Cloud refers to a pool of configurable computing resources like networks, servers, storage, applications and services that provides an on-demand access to these resources. The term is widely used in context of new architecture of networked systems that works as an on-demand model. A server can be referred to as a dedicated computer that provides services for one or more purposes. Servers are assigned heavy-duty back end tasks.

Cloud refers to a pool of configurable computing resources like networks, servers, storage, applications and services that provides an on-demand access to these resources. These servers are associated with various types of services that are provided through the internet. Thus, the term cloud is also considered as a metaphor for the 'internet'. Cloud scales according to demand, which means that the user only needs to pay for specific services that he requires. High performance of computing power is achieved by this cloud model. Cloud computing services are offered by various companies like IBM and Infosys.

Servers can be described as dedicated computers that provide services to other computers. The services depend upon the need or requirement. Servers are assigned some important tasks that are needed to be done in the backend. However, the dependency on these back end processes is quite high. One can differentiate servers from the normal computers as these servers consist of systems of disks. Generally, the desktops have a single hard drive, whereas in a server, various hard drives are configured to serve important purposes. All these disks appear to be a single disk to the user.

Definition

Cloud refers to a pool of configurable computing resources like networks, servers, storage, applications and services that provides an on-demand access to these resources.

Servers can be described as dedicated computers that provide services to other computers.

Characteristics

  • On demand self service
  • Broad network access
  • Resource pooling
  • Rapid elasticity
  • Measured service
  • Secured
  • Monitored
  • Backed up
  • Manageable

 

Types

  • Public Cloud – It is opened for use by the general public.
  • Private Cloud - It exists within the boundaries of an organization.
  • Hybrid Cloud – It is a mix of private and public clouds. General applications are handled by a public cloud, and some critical applications are managed by an organization on its own.

 

  • Application Server – It is commonly used to connect the database servers with the users.
  • Chat Server – It exchanges the data in real time.
  • FTP Server – it is used for secure transfer of files between the computers.
  • Proxy Server – it is a mediator between a client program and external servers.
  • Groupware Server – it enables the users to work together irrespective of their locations.

There are many other types of servers too.

Example

Google Drive is used for the storage. This kind of storage is found online. It is available in deskops, tablets and even in smart phones.

A blade server is a stripped down server that is designed to be fully modular.
