From Datacentres to Cloud: How Computing Changed Through My Career

When I started my career, infrastructure was something you could touch. Servers sat in racks. Cables ran between switches. If something went wrong, you walked to the datacentre, physically seated a card, checked a link light. The work was concrete in a way that’s hard to explain to engineers who started their careers writing Terraform.

That world is largely gone now — or at least it’s hidden behind layers of abstraction. But I think starting there gave me something that’s quietly useful: an understanding of how computing actually works, from the bottom up.
