Azure - Resource Groups

An Azure resource group is a container that we use to manage related resources for an Azure solution.

Some Important Considerations to keep in mind

• All Resources within a Resource Group should be on the same lifecycle. If a server within a resource group need to be on a difference cycle, then it should be in a different resource group.

• Any Azure resource can exist in only one Resource Group.

• When you delete a Resource Group, all the resources within that group will be deleted as one operation.

• Resources can be moved from one group to another group anytime.

• Any tags that are given to the Resouce Group, will not be applied to the resources within the group.

• A Resource group can be created in 1 azure location and the resouces within can be created in another location. But it is recommended that they all be in 1 azure location.

• Azure access policies, roles and resource locks can be used to manage a Resource Group and its resources within.

• we can deploy upto 800 instances of a resource type in each resource group. (some exemptions are there in place for some resources)

Resource Group Location

When we create an Azure Resource Group, we need to provide an Azure Location.

Resource Group Location stores metadata about resources. This means that when a resource is created within the resource group, we are specifying where the metadata of the resources needed to be stored. We need to make sure the compliancy is met.

It is recommended that the resource group and the resources are created in the same location. Typically this location is closest to where the operations are.

If a resource group region isnt available, we wont be able to update the resources and the write operations are blocked. The updates to the resources are not made since the metadata of the resources arent available.

How to create a Resource Group

1. Login to Azure Portal, You will see something like this, with the most recent or favorite resources in the middle and quick links to Azure resources on the Top, Bottom and to the side.

   

2. Please click on “Resource Groups” (marked below)

   

3. It will open the Resource Group Dashboard as below and click on “Create”

   

4. This opens a form with 3 steps (Basics, Tags and Review+Create), fill in the form and the Resource Group is created.

   

   In the Basics Panel,

   • you need to pick the right subscription this Resource Group needs to go into (very important, since this cannot be changed).

   • give a valid name

   • pick a region, where you want this resource to be created.

In the Tags Panel,

• This is a Key(name) and Value combo, the name is case-insensitive but the values are case-sensitive.

In the Review + Create Panel,

• We have one last chance to review the information provided and click on “Create” to have this Resource Group created.

5. Your Resource Group is created in the specified region with the specified name and under the selected Azure Subscription.
