Why it matters

The cloud conversation moved from migrate everything to deciding what goes where. That maturity is a good sign, but it also makes the discussion harder: there is no single answer any more, it has to be argued case by case, and very few people have the numbers to do it.

I separate what moves for cost from what moves for capability. Migrating to save money almost never works; migrating to be able to do something you could not do before does. When the argument is only savings, it is worth checking the numbers again because they are usually incomplete.

What usually goes wrong

Where it usually breaks is team capability. The platform is new but people learned on the fly, with no time and no support. They end up replicating data-centre practices in the cloud, which means paying cloud prices for benefits that never arrive.

What to watch

  • Three-year total cost with real growth, not the first-year promotion.
  • How hard it would be to leave or move a piece to another provider, which is future negotiating power.
  • Who sees the bill and in what detail: with no owner for the spend, the spend grows on its own.

How I read this entry

What I would install alongside any move to the cloud is the discipline of switching things off. Tag everything by owner, review monthly what is running unused, and give somebody the authority to turn it off. Without that, waste eats the promised savings within two years.
