how to run web app on multiple instances

Question

I have a web app, and am under the impression that I need to deploy it to multiple instances.

What precisely does this entail? Is this scaling out?

If not, how do I proceed?

TIA

Hi,

If the load/needs of your app requires it, you can have it running on multiple instances (Scale out). The incoming requests will be balanced across all running instances.

For Standard tier plan and higher you can configure autoscale, which allows the number of instances to scale out and in automatically. For example, with autoscale you could configure it to increase the number of running instances by 1 if CPU is greater than 70% for 10 minutes, and decrease the number of instances by 1 if CPU is less than 50% for 15 minutes.

For Basic tier plans only manual scale is supported, which is what you see in your screen shot.
