Understanding Cloud Computing and Cloud Server

Posted by Jamison on 12 05 2016.

Cloud computing is used to refer to several activities, wherein, the computing resource is provided through the use of network connection, which is usually the Internet. It is similar to ‘utility computing’ because users can gain access into several computing resources instead of managing the equipment required to produce the computing resources. Another common similarity is consumers getting access to national supply of electricity, rather than operating a generator of their own.

 

Flexibility and Scalability

 

A characteristic in which cloud computing is described is flexibility and one way of manifesting its flexibility is by scalability. Scalability is the system’s ability to conform and adjust to any alterations in the workload. The cloud technology permits automatic resource provision or de-provision whenever it is necessary, ensuring that the resource is available to nearly match current demand. In cloud computing, consumers who use it will pay only the resource used. In a sense, cloud computing…

A characteristic in which cloud computing is described is flexibility and one way of manifesting its flexibility is by scalability. Scalability is the system’s ability to conform and adjust to any alterations in the workload. The cloud technology permits automatic resource provision or de-provision whenever it is necessary, ensuring that the resource is available to nearly match current demand. In cloud computing, consumers who use it will pay only the resource used. In a sense, cloud computing avoids not only redundancy in operation expenses, but also inefficiencies.

 

Clients such as business executives, merchants and private individuals can avail of cloud services through cloud hosting. Cloud hosting providers deliver hosting services to web sites through virtual servers, which pull the client’s or web site’s computing resource from networks of web servers. In a nutshell, in cloud hosting, the servers used are massive and pulled from varying data centers located in different areas.

 

Cloud Servers

 

Information, data, web tools and applications are stored in, shared with and retrieved from cloud. In a sense, the cloud servers perform similarly as do the physical servers, but they differ in their functions. So when organizations, businesses and individuals engage cloud hosting services, they are actually leasing space in virtual server than purchasing or leasing physical servers.

 

Shared Hosting and Dedicated Hosting

 

In cloud computing, clients face two choices: to avail of the shared hosting or the dedicated hosting. Between the two, shared hosting is more affordable because there is no exclusivity in using the server. This means, clients of one particular cloud computing provider can share one or two servers. This means, too, that a web site belonging to a client is hosted by the provider on a server, where web sites of other clients are also hosted. Though shared hosting is more affordable, it has several drawbacks including inflexibility of its setup and incapability of coping huge traffic.

 

On the other hand, in dedicated hosting, the clients pay for the entire physical servers. This means that the whole server is exclusively dedicated to a particular client only. In some circumstances, the organization or business may use several servers all of which are dedicated exclusively for their usage. Unlike in shared hosting, clients in dedicated hosting have complete control over the servers hosted. However, on the down side, in dedicated hosting, the needed capacity should be predicted with processing power and sufficient resource to deliver the expected levels of traffic. When the capacity is underestimated, it could result in underperformance during peak periods. If it is overestimated, it will lead to unnecessary expenses.
