  • 1) By outsourcing the ownership of the underlying assets, we can avoid the need for costly capital expenditure and allow organisations which may not have investment capital at the moment to move forwards through operational expenditure.2) The virtual resources allow us to shorten lead times by having underlying capacity already available and through automation and ease of provision.3) Elastic resources are able to stretch to fit, scaling up and down as required. No longer is IT an every increasing cost regardless of business performance.4) Pay as you go pricing also helps avoid capital expenditure, but also reduces overall cost in the short term5) Only data centres that are of a scale to host multiple organisations can realise the economies of scale that will significantly reduce the carbon footprint. For instance Telehouse in London’s docklands are pioneering a scheme to reuse the hot air generated by the data centre to heat nearby homes.6) Again, the simplicity with which resources can be accessed and used increases the speed at which we can get tangible results.7) And finally the geographic freedom to run a global organisation. Being web based also gives us additional benefits – for instance, most of your offices will already have network connections. If you host less in your data centre, then you can reduce or even at the extreme eliminate the cost of your data centre Internet connection and other costs.

    • 8. Definition<br />Cloud computing is on-demand access to virtualized IT resources that are housed outside of your own data center, shared by others, simple to use, paid for via subscription, and accessed over the Web<br />http://www.informationweek.com/cloud-computing/blog/archives/2008/09/a_definition_of.html<br />
    • 9. SaaS vs. IaaS vs. PaaS<br />Software as a Service (SaaS): Complete application systems delivered over the Internet on some form of &quot;on-demand&quot; billing system: Salesforce.com, Google Apps…<br />Platform as a Service (PaaS): Development platforms and middleware systems hosted by the vendor, allowing developers to simply code and deploy without directly interacting with underlying infrastructure: Google AppEngine, Microsoft Azure, Force.com…<br />Infrastructure as a Service (IaaS): Raw infrastructure, such as servers and storage, is provided from the vendor premises directly as an on-demand service: Amazon Web Services, GoGrid…<br />http://news.cnet.com/8301-19413_3-10140278-240.html<br />
