Since Sitecore 8.2 update 1, we can simply scale our App Service plans up or out. You can find these options on the App Service Plan as well as the App Service themselves.
Scaling up means selecting a different tier for our subscriptions – more RAM and cores for instance.
As you can see, I’m currently running on the S1 tier – which I can’t recommend to anyone as it’s quite slow (of course, it is way below the minimum specs found in the installation guides)…
Our other option is to scale out. That means we can add (or remove) a number of instances based on… something. Let’s take a look.
