So I’ve spent this evening touring BT Dial House in Manchester. It’s a huge telephone exchange, and brings telephony and Internet access to Manchester. Wanna see some photos and nerd out with me? A thread ... #internet #telephony #infrastructure This is just one of the marine diesel generators that live in the lowest basement. The site has its own dual redundant HV feed, and operate their own HV/LV transformer kit. They take ~600 litres of oil, and are regularly tested.

I stood up a Kubernetes cluster from scratch this evening, to get a better understanding of the internals. You see, I’m building a new web service, and I’m thinking about deployment strategies. K8S was top of mind. Here’s some thoughts. Firstly, it’s a pretty involved process, with a bunch of decision points at every turn. I was console and CLI prodding, but I’d want to script all this. I value infrastructure as code too. That’s another rabbit hole: CloudFormation vs Terraform vs CDK vs DIY.
