There is praise here for using Linux in the datacentre and its use is continuing to grow. However, there is criticism with regard to high availability – even though the linux kernel is “pretty solid”, it is quite clear that setting up high availability is a pain in the proverbial. So instead of all that [...]

More anecdotal evidence that uptime matters. We consumers have very high expectations these days. And it’s not just uptime either – quality of service (and response times) are paramount too.

This is covered admirably in this article. Another, less publicised and equally recoverable downside is that you could be compromising your availability by hosting [...]

It is, in most companies, the default deployment option: you have to make a case for why not to virtualise, according to this article.

Read through some older posts on this blog and somewhere (quite often actually) you will find reference to the impact of services being unavailable – in the IT world this is referred to as downtime. Now, I don’t want to pick on any company in particular, but the consequences of systems unavailability is dramatically highlighted [...]

Another big name unveils a cloud package with some interesting twists. Although it sounds quite complex, I must say the concept of a 3D cloud boasting a 360 degree view to tackle the toughest business challenges does sound intriguing.

Can you spot the third tier? I read through Combining HA and BCA Best Practices a couple of times but could only come up with two. They talk about non-mission critical (is there such a thing these days?) and mission critical. I would suggest the third tier ought to be fault tolerance where HA will [...]
