How to get edge computing right
We end up explaining this on discovery calls often enough that it deserved writing down. The short answer to edge computing is that it is mostly a sequence of small decisions, not one big one.
The bill is a design document: it tells you exactly what your architecture actually does. It rarely shows up as a line item, which is exactly why it slips.
The reason this keeps coming up
Running closer to users removes latency you cannot optimise away. That sounds obvious written down. It is still the thing most often skipped. If it only works because one person remembers to do something, it does not work yet.
The steps
- Establish what you have today before changing anything
- Great for caching and routing, awkward for state
- Debugging across many locations needs deliberate tooling
- Write down the decision so the next person does not re-litigate it
Debugging across many locations needs deliberate tooling. In practice this is a scheduling problem more than a technical one. It is the sort of thing that looks like polish right up until it costs you an enquiry.
Turning this into a decision
The short version
Cloud work rewards teams who automate early and punishes teams who click through consoles. Three things worth confirming about edge computing before you move on:
- Someone can say what the current setup is without going to look
- Great for caching and routing, awkward for state — 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.
