You tapped View Product.

Five Azure services answer before the page paints. Here is the order they run in.

What you'll learn

  • Why the edge answers first and your API never hears about a cache hit
  • What cache-aside actually does on a Redis miss, including the write-back
  • Why product images take a different path and never reach your API

Understand it one step at a time

The short runs these in order in about 50 seconds. Here they are written out — pick any step to jump the short straight to it.

1 Step 1 of 12

You tap View Product

One tap on a phone screen. Everything after it happens somewhere in Azure, and the whole chain has under a second to finish.

Frequently asked questions

What happens first when a shopper taps View Product?
Azure Front Door, the edge, answers directly from its cache when it can — on a hit, the request never reaches your API at all, which is why the edge cache is the layer that stops the most traffic before anything else runs.
What does the cache-aside pattern do on a Redis miss?
On a miss, the API reads from Azure SQL, then writes that result back into Redis before returning it, so the next request for the same product hits the cache instead of the database.

These are built for a phone

Every short is drawn at full portrait height, the shape a phone already is. Installed, it opens full-bleed with no address bar across the top — and the whole library reads offline.

Twenty seconds gets the shape of an idea across. These go into how it behaves in production.
