Microsoft has a lot of products on the Microsoft Azure website. You can use it for data migration purposes. You have Azure Data Factory, AZCopy, Azure Storage, data lake services, and analytical services. Depending on the kind of migration, you can pick from any of those services. The combination of services also depends on the data, whose data you have, etc. Based on that combination, we create a solution for data integration.
In Azure Resource Manager, you can manage services in different projects, in different environments, and with different tenants. It helps us put the hierarchy in place. Based on the hierarchy, people will get the role and everything, and we can centrally control it.
If I have applications that require certain services like Azure Services, I can assign them. I have other web applications that require web-related applications, and I can segregate my users. I can segregate my team based on that.
I haven't used Resource Management extensively to control access thoroughly. I don't try to code anything here. I'm mostly using the common functionalities and not anything else.
