What is the CPU cores and RAM assigned for azure function consumption plan for one instance ? How many instances we can scale up in japan east region ? Can we integrate virtual network for functions consumption plan ?

The max memory on the consumption plan is 1536mb, CPU allocation is not a published meter. You cannot join a consumption plan function to a vNet, you would need to use the premium version. The limit on scaling out a single function is 200 instances.

is there some docs on this? @Sam Cogan

Hi @venkataS-2479

Adding reference article to @Sam-Cogan answer.
No vNet supported in consumption Plan: https://learn.microsoft.com/en-us/azure/azure-functions/functions-scale#hosting-plans-comparison
Can be maxed out to 200 Instance for consumption plan: https://learn.microsoft.com/en-us/azure/azure-functions/functions-scale#understanding-scaling-behaviors
Max Memory supported: https://learn.microsoft.com/en-us/azure/azure-functions/functions-scale#how-the-consumption-and-premium-plans-work

Thank you @Sam-Cogan for your answer.
Could you please help me to understand this scenario.
Scaling out to 2 instances from 1 instance in premium or app service plan. we are going to be assigned as double of the resources(vCPU and RAM) is the same way it's going to be applied on consumption plan also ?
means once function scaled out in consumption plan is 3 GB of RAM is going to be assigned to our function app ?

@venkata S There will be two instances having 1.5 GB of memory each instance.
