The real cost of ignoring serverless
This is cheap to get right at the start and expensive to retrofit. Nobody bills you for neglecting serverless. The cost shows up somewhere else.
Cloud work rewards teams who automate early and punishes teams who click through consoles. It is the sort of thing that looks like polish right up until it costs you an enquiry.
Where the cost lands
- Time spent on work that should not have been necessary
- Enquiries that quietly never arrive
- Excellent for spiky, event-shaped workloads
- Rework, once the problem is finally visible
Cold starts and vendor coupling are the real trade-offs. Where this goes wrong is almost never a lack of knowledge. Budget a little time for it every quarter and it never becomes a project of its own.
What to do next
Cost modelling matters more here than anywhere else. It is worth being explicit about, because assumptions differ quietly. It is worth deciding this deliberately rather than inheriting whatever the last person set up.
What this looks like day to day
Operability is a feature, and it has to be built rather than bought. Three things worth confirming about serverless before you move on:
- Someone can say what the current setup is without going to look
- Cold starts and vendor coupling are the real trade-offs — and you know whether that is true here
- There is a way to tell whether the last change to this helped
Most of the value here comes from doing the first two things, not all of them.
