The Bits blog from the New York Times ran an interesting article a couple of weeks ago called ‘How Fast Can a Cloud Run?’ (you’re right, I’m still catching up with my reading!). It talks about a service called CloudSleuth, which measures the speed of response of various cloud services.
Our Microsoft Azure cloud came out on top (I’d like to think I’d still be writing this, even if it didn’t).
But the thing that interested me was the impact of geography on response times. I used to remember the good-old-days-of-the-Internet, when the service would start to slow down to US-based websites from around 2 o’clock in the afternoon – which coincided with people waking up and getting online on that side of the Atlantic. But that was a decade ago or more – I’d forgotten all about it.
The chart above, snipped just now from CloudSleuth, shows the picture that caught my eye. Basically, the closer you are to the datacentre, the better your cloud experience is going to be. And because most datacentres are in the US, that’s where the best response times are.
It sparked off a few of thoughts:
Well, it’s pretty clear that the answer depends on a variety of factors:
