This is the second in a two-part special of Technology Untangled, in which we take a look at some of the challenges of cloud computing and how we can work around them.

In the last episode, we looked at the ways in which the cloud hasn't necessarily delivered on its promise of an always-on, cost-effective, scalable solution to organisations' computing needs.

At least, not for everyone. If you haven't listened to that one, go back and have a listen first.

There's some flawed economics here, because you can't realise those cashable savings until the last

workload leaves the data center.

And a good example would be relatively small company. We could easily move them to the cloud,

but the piece of equipment that they needed to be able to talk to the cloud service cost

over two million pounds to replace. What if 75% of banks rely on the same service providers in the back end and that provider fails?

And suddenly the financial system of the UK turns off.

We're looking at a situation of basically financial meltdown that makes the 2008 crisis look like you just dropped your pocket money.

This time around, we'll be looking at some of the solutions to these problems,

from getting the right people in to help bridge the gap between cloud and on-premise computing,

or just looking at solutions which get the best out of cloud,

whilst also meaning you don't have to throw away a two million

quad microscope or particle accelerator or whatever other piece of equipment could possibly cost that much.

Yeah. You're listening to Technology Untangled, a show which looks at the rapid evolution of technology and unravels the way it's changing our world. I'm your host, Michael Bird.

Now, we'll start this episode off by saying that in a load of ways the cloud is brilliant.

It's flexible, it's scalable, and putting your old data centre somewhere else frees up office space

so you can install an ice wrinkle, whatever else you need an enormous cold space

for. If you're a startup or reasonably young business, the cloud is probably everything you need,

but there can be a load of issues for more established firms who spent huge amounts on mainframes

and other capital expenditure several years or even decades ago, which they now can't easily migrate off.
