Cloud computing is a model for enabling ubiquitous network access to a shared pool of configurable computing resources. This slide set provides an introduction to cloud Computing. It briefly talks about fundamental cloud services, Benefits of Cloud based Web hosting solution, Comparison of pricing with service provider and Limitations of Cloud based Web hosting solutions.
2. You are required to setup and install a small network and set of
servers to support a small company which operates a tomato
packing plant. The plant operates in a small regional town and
has 10 permanent employees and around 25 part-time and
casual employees.
The company requires a forward facing (connected to the
Internet) Web Server that is located onsite in the main office.
The National Broadband Network has just been enabled in the
area so a high speed Internet connection is now available.
An existing file server,TommyToe, used by the permanent
employees to store various documents, spreadsheets, databases,
etc., will need to be integrated into the new network.TommyToe
runs Microsoft Windows Server as the operating system and is
backed up daily via an attached high speed tape drive with
suitable software. All new servers should mount a shared space
on TommyToeto save backups to. These will then form part of
the backup process already operating on the TommyToe server.

3. A framework of computing is cloud
computing.
It allows the consumers to apply of a subset
of resources from massive pool of hardware
and networking infrastructure.
This infrastructure is managed externally by a
service provider.
It can quickly be deployed and discharged.

the Web hosting system or to switch to another
cloud-based one.
It lowers the operating expenses through
lowering the cost of energy, maintenance,
assembling and upgrades.
Among the top benefit of cloud based Web
hosting, quick implementation is the most
component part.
To make the model limit very versatile, there is a
need for the resource pooling and the quick
resource flexibility.
