what is cloud computing?

What exactly is cloud computing?And where do I find it?

Cloud computing is about moving stuff online

Who’s got their own power plant?

From here on…• Computing resources will be increasingly online• They will become ubiquitous – you will access

them like you do electricity. Just switch on. Or off.

How we are today (in general)• Local computers• Servers to buy and manage• Software to buy, manage and update locally• Manage gateways for remote access (or not)

How we will be• Someone else manages the servers – we pay for

what we use• Capacity can be upgraded/downgraded on the fly• Software updates happen incrementally and

without any input from us. We’re always up to date

• We can access all our data from anywhere – via desktop PC, laptop, mobile phone. And it’s always in sync. Change a document on your phone and it’s changed when you access it from your desktop

Easy• Need fewer? Downgrade your

subscription• Need a different type of software

for one person? Try before you buy and get it in minutes.

• Less of – I’ll check that when I get back to the office

• More of – I can do that now

OK – what are the risks?

Security, Privacy, Reliability• Unauthorised access to cloud data• Loss of data• Loss of access to the internet• Hosting location (data protection

issues)• Security of hosting organisation

It’s a question of balancing risk with

reward
