Azure Stack CSP Query

Gaurav_Naithani - there are a few links providing some of the info you are looking for, starting with:

• “Getting started with Azure Stack for CSPs” whitepaper -> https://aka.ms/AZSforCSP  
• Manage usage and billing for Azure Stack as a Cloud Service Provider -> https://docs.microsoft.com/en-us/azure/azure-stack/azure-stack-add-manage-billing-as-a-csp
• Multi-tenant subscription delegation and support ticket creation for CSPs -> https://aka.ms/AZScspMultiTenant
• Registration and Management of tenants on Azure Stack, for CSP partners -> https://aka.ms/AZScspRegistration
• Linking Azure Stack Hub to a customer billing system -> https://aka.ms/azstackCSPusage
• Hoster licensing guide - https://azure.microsoft.com/files/Pricing/Details/AzureStack/azure-stack-hub-hosters-service-providers.pdf

The capacity planning is a complex topic when you have a multi-tenant environment. For a Managed Service Provider, it's a bit easier as you control (to a degree) the type of workload deployed - but for someone providing "just the platform" it's much more complicated as you have less visibility on what each of the tenants are doing. There is a tool that can help (https://docs.microsoft.com/azure-stack/operator/azure-stack-capacity-planner) but the assumption is you (as the AzStackHub Operator) would know more about the workloads you plan to deploy.

There are some hints you can also learn from the Azure Stack Hub Partner Solution Series - Microsoft Tech Community where we've published a number of Service Providers (more geared towards providing Managed Services to their customers) ... and you should definitely start a discussion with you Microsoft account team to help guide you on the right path.
