Edge workers are tempting for tagging and a poor fit for almost all of it. The use cases that survive close inspection are narrow.

The short version: a clear story of which workload runs where is mostly a matter of doing the obvious thing carefully. Use the edge for routing and lightweight enrichment; keep the canonical event handling in your server container where you have more visibility and controls.

You add another runtime to your stack. Make sure it earns its keep. That trade-off is the one most teams underweight when they plan the work, and it is the one that quietly determines whether the project ships on time.

If you want a longer treatment, we have a deeper post in the series. For now, the takeaway is small enough to fit on a sticky note: Edge is not a replacement for sGTM. It can be a useful complement when used sparingly.
