What is cloud computing and what can it do for me

The term cloud is used as a metaphor for the internet. Cloud computing is a general term for anything which involves delivered hosted services over the internet.

In broad terms a cloud service has three characteristics which differentiate it from traditional hosting, these are;

  1. It is provided on demand (by the minute or hour in some cases)
  2. It is scalable (a user can have as little or as much as they want)
  3. the service is fully managed by the vendor (you typically only require a computer and internet access)

Cloud computing promises to speed application deployment and lower costs, whilst increasing business agility. It has transformed the way we design, build and deliver applications to the users. Have you used a search engine today?, have you accessed web mail if so you are already using cloud services.

There are public clouds, private clouds and hybrid clouds but don’t let the jargon put you off, everyone agrees that cloud computing is the key to the future of I.T but lots of these people are unsure of what it is. Many companies are jumping on the bandwagon to offer “cloud services” so it is worth understanding such terms as SaaS (software as a service) or PaaS (platform as a service) or IaaS (infrastructure as a service) to name a few if you need to evaluate a suppliers claims.

Cloud computing has some real benefits but also has risks such as loss of services if your provider has downtime or worse still goes out of business also regulatory concerns over data security so choose your vendor carefully.

I recently setup a really simple system for a plumber who lives down the street; he already had an iPhone, an Apple Mac and an iPad although in his words he wasn’t really sure what to do with them. During our conversation he mentioned that his wife mans the phone at home and jots down all of his incoming appointments then rings him at regular intervals to give him the new list, if the call is urgent she tries to call him straight away, within 10 minutes we had connected his Apple Mac, iPhone and iPad calendar applications up to iCloud (he was familiar with the calendar app anyway), now when his wife enters the call details into a time slot on the calendar app on the Mac the appointment appears on his iPhone and iPad almost instantly and any Urgent appointments are highlighted in red, he now knows exactly when and where he should be, what the problem is before he gets there, the address and customer name and contact details and it cost him nothing as he already had the technology simple, but had this come up a year or two ago it would have been a little more difficult and a lot more expensive to achieve, it’s certainly not the best solution to his problem but it works for him and cost him nothing.

The reason for the anecdote above is to show that the “Cloud” isn’t frightening or intimidating, it’s not the answer to everything but in certain cases it does exactly what it says on the tin.

To conclude, here are a few more terms you may want to research if you want to know more, it is a fascinating subject.
