Azure App Service Plan and Resource Group Planning

Praveen Sreeram

We are migrating all our 25 portals to Azure. All these portals point to a single database. These websites are associated with 25 different companies who are customers of our client.

We have planning to have the structure something like this. (1) Create 25 Resource Groups (2) Create 25 App Service Plans (3) Create 25 App service - Web apps

My Questions:

Is it suggested to have both the web apps and the database (SQL Database) in the Same Resource Group?
We would like to leverage the auto-Scale-Out feature separately for each of our portals and so we planned to have a separate App Service Plan. Is that good?

Thanks,

Prawin

Accepted answer
Resource group is nothing but the logical grouping of your resources e.g. all resources required for development portal will reside in a group while staging resources in another. So in your scenario - its completely up to you that how do you want to have the separation. It might be based on application types or by some other distinguishing factor. It would make more sense to keep the Azure web app and it's database in one resource group for better management.
About second question - App service plan is nothing but the plan of your server capacities so instead of creating 25 multiple plans you might want to do the capacity planning and group the applications by required capacities and then only create those many app service plans.

Hi,There,

I am also trying to figure out the good way to distinguish App Service Plan vs. Resource Manager. Technically, they are all container like other post said. so it does NOT matter how you plan it.

Although that there are other non technical elements in play, which I was told be someone else.

1. Resource Group is also a BILLING container, which includes everything storage, network and obviously compute. So one can easily do charge back or bill back to client or business. App service plan does not involve storage and network.
2. Resource Group can cross region, app service plan can NOT, so if you are design a GEO redundant design, the out most container can be resource group, but NOT app service plan.

thanks.

Thanks @Bhushan Gawale, That's what we have done. Just to add to your words,
Have both your Front End Web App (or any other service / component) and your Backend database to be in Same Resource to avoid latencies.
As you righly said, we have planned to create few groups (App Service Plans) and configure our Our App Services to them. In case if there is a spike for any of our customer then problably, we take a separate App Service Plan and configure the same for it to that Load Period and also problaby enable Load Balancing.
Thanks,
