Five mistakes teams make with edge computing

The version of this that works is simpler than the version most people imagine. These are the ones we run into repeatedly when we audit edge computing.

The bill is a design document: it tells you exactly what your architecture actually does. Anything you cannot measure here, you are deciding by taste, which is fine as long as everyone knows it.

The mistakes we see most

• Treating it as a launch task rather than an ongoing one
• Assuming someone else already owns it
• Running closer to users removes latency you cannot optimise away
• Great for caching and routing, awkward for state
• Never checking whether the fix actually worked

Debugging across many locations needs deliberate tooling. In practice this is a scheduling problem more than a technical one. It is worth deciding this deliberately rather than inheriting whatever the last person set up.

What to do next

The short version

Operability is a feature, and it has to be built rather than bought. 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.
