Cloud: from on-prem racks to serverless edge
Twenty years ago, you owned servers. Ten years ago, you rented them. Today, you don't even know which machine your code runs on.
Before · the closet under the stairs
Every company over a certain size used to own servers. They lived in a back room, a closet, eventually a co-located data centre. Capacity planning was guesswork. Outages were the IT manager's problem at 2 a.m.
The first cloud era — EC2, S3 — kept the same mental model but rented the metal.
Now · everything-as-a-service
Modern cloud is a buffet. Managed databases, serverless compute, queues, AI APIs, edge networks. The shift is from "deploy a server" to "compose services". Developers ship faster. Bills get harder to predict.
Container orchestration (Kubernetes) won the platform wars but lost the simplicity argument. Most workloads are now better off on managed PaaS or serverless.
The next decade · edge + AI
Compute moves closer to the user. Edge platforms (Cloudflare, Fastly, AWS Lambda@Edge) run application logic in dozens of cities globally. AI inference happens at the edge for latency, then aggregates centrally for training.
Cost optimisation becomes its own discipline. The companies that don't track per-customer cloud cost will discover their margins eaten by services they didn't know they were running.
