Probably not.

On Tuesday 8th June, at roughly noon in mainland Europe, the impact of a major outage swept across a number of the world’s most significant websites. The issues resulted from a failure of Fastly’s content delivery network service. …

(This is part two of a series exploring Complexity Science and the concept of complex adaptive systems in the context of ITSM. The first article, a primer for ITSM on these concepts, is here)

The UK’s Times Newspaper recently broke a story (paywall) alleging personal data breaches by members of the country’s new and hurriedly-assembled COVID-19 contact tracing workforce. This is obviously a significant story, but one particular line caught my eye:

I presented yesterday (June 27th 2019) at the excellent DevOps Enterprise Summit, in London. The presentation is here and I’ll link the video when it is published.

One thing that was particularly interesting to me was the view from the venue, over the Thames, to the Isle of Dogs.

“Distributed systems have an infinite list of almost impossible failure scenarios”

So said Charity Majors at the 2019 Configuration Management Camp conference in Belgium. You can watch Charity’s amazing presentation in full, here:

The talk highlighted the difficulty of performing traditional testing, deployment and monitoring, when building and deploying…

I like to joke that I went to my first DevOps conference by accident. It’s actually pretty-much true. While browsing for interesting reading back in late 2014, I came upon the website of Configuration Management Camp, aka #cfgmgtcamp, in Ghent.
