What is Azure Resource Manager?

Azure Resource Manager is the deployment and management service for Azure. It provides a management layer that enables you to create, update, and delete resources in your Azure account. 

How resource manager plays a role?

If a user sends a request from any of the Azure tools, APIs, or SDKs, the Resource Manager receives the request. It authenticates and authorizes the request. The resource Manager sends the request to the Azure service, which takes the requested action.

what is the benefit of using Resource Manager?

You can manage your infrastructure through declarative templates rather than scripts.

All the resources for your solution can be deployed, managed, and monitored as a group rather than handling these resources individually.

you can redeploy and define the dependencies between resources.

 What is a Resource group?

• A resource group is a collection of resources that share the same lifecycle, permissions, and policies.
• Resource group - A container that holds related resources for an Azure solution. The resource group can include all the resources for the solution, or only those resources that you want to manage as a group. You decide how you want to allocate resources to resource groups based on what makes the most sense for your organization
• Each resource can exist in only one resource group.
• When creating a resource group, you need to provide a location for that resource group. You may be wondering, "Why does a resource group need a location? And, if the resources can have different locations than the resource group, why does the resource group location matter at all?" The resource group stores metadata about the resources. When you specify a location for the resource group, you're specifying where that metadata is stored. For compliance reasons, you may need to ensure that your data is stored in a particular region. 
• If the resource group's region is temporarily unavailable, you can't update resources in the resource group because the metadata is unavailable. The resources in other regions will still function as expected, but you can't update them.
• You can deploy up to 800 instances of a resource type in each resource group.
