The Cloud Computing world has undergone rapid growth in recent years, and is continuing to grow at an ever increasing rate. There are various definitions of the term ‘Cloud Computing’ on the internet which can lead to confusion. Essentially all ‘Cloud Computing’ means is that the computer systems in question are not housed physically within an organisations offices – they are held elsewhere (out in ‘The Cloud’).
Most large organisations use Cloud Computing in some form already, by co-locating their servers outside of their data centre and using the internet to connect the internal users to these systems. This approach is much less desirable to many businesses as you still need to purchase, install & manage the servers (both hardware and software) which leads to higher cost of ownership and longer return on investment (ROI).
Public cloud is where the ‘real’ change is taking place. Salesforce.com is probably the best example of a public cloud offering; public cloud is where you’re offered a system or service over the internet, typically provisioned automatically (and immediately) where you don’t need to undertake any ownership of the back-end systems that are used to deliver that service. Some providers may be open about the technology used to deliver the service, some may keep it a secret… ultimately you don’t need to care so long as they offer the required service levels and functionality.
We’ve put together a Top 10 Myths of Cloud Computing to help our clients understand this new technology, however should you have any further questions please feel free to contact us. There are also other ‘Cloud’ terms being used today (e.g. Hybrid Cloud & Community Cloud) and no doubt the list will continue to grow – for further details check out the Wiki on Cloud Computing.
