In our previous article "Cloud Computing Defined in 7 Ways"we gave you basic idea on cloud computing now we'll little deeper into the concept.
So Lets begin , In simple topological sense cloud computing components is made of several element such as
Now each element play a specific role in delivering the cloud function.
Now thin computers are that do not have internal hard drives, but rather the server
do all there work and then display the information.
- THICK CLIENTS
Now these are regular computer that do contain internal hard disk,and use web browser
(Firefox, opera,internet explorer)to connect to the cloud.
NOTE: (Now thin computer are becoming relatively popular solution for the cloud
because of its price or effect on environment)
Some benefits of using Thin Clients are
-> Lower Hardware cost
-> Lower IT cost
-> Security
-> Less power consumption
-> Less noise
-> Ease of replacement of hardware
Amazon has there cloud solution in servers all the world,if something goes wrong for instance causing a failure on one site, the service will not be stopped it would be accessed through another site also if the cloud needs more hardware they did not need throw more server in the safe room they can add them at another site and simply make it as part of the cloud.
So Lets begin , In simple topological sense cloud computing components is made of several element such as
a) Clients
b) Datacenter
c) Distributed server
Now each element play a specific role in delivering the cloud function.
a) CLIENTS
Clients are the device that the end user interact to manage their information on cloud.
they generally divide into 3 categories
>MOBILE > THIN > THICK
they generally divide into 3 categories
>MOBILE > THIN > THICK
- MOBILE CLIENTS
Mobile device include (PDA, SMARTPHONE, or IPHONE)
now these device are portable and work on wireless access of network, through Internet.
- THIN CLIENTS
- THIN CLIENTS
Now thin computers are that do not have internal hard drives, but rather the server
do all there work and then display the information.
- THICK CLIENTS
Now these are regular computer that do contain internal hard disk,and use web browser

-> Less power consumption
-> Less noise
-> Ease of replacement of hardware
b) DATACENTRE
Now datacentre is collection of server where application to which you subscribe is housed, it could be a large room in basement, or room full of server which you access through internet.
Now the growing trend in IT sector is using visualization ie (using virtual server) in this software can be installed allowing multiple instances of virtual server to be used in this way we can have half dozen of virtual server running on one physical server.
NOTE: (The number of virtual server that can exist on a physical server depend on
the SIZE & SPEED of the physical server which runs the application of the virtual server).
the SIZE & SPEED of the physical server which runs the application of the virtual server).
c) DISTRIBUTED CLIENTS
Now the server don't have to be housed in same location often server are in dispersed geographically location but to you the cloud subscriber,these server acts if they are humming right away next to each other. This gives the service provider more flexibility in option and security.
FOR EXAMPLE:
Amazon has there cloud solution in servers all the world,if something goes wrong for instance causing a failure on one site, the service will not be stopped it would be accessed through another site also if the cloud needs more hardware they did not need throw more server in the safe room they can add them at another site and simply make it as part of the cloud.
