Before we look into the Fabric Capacity, let's get into different licensing models. There are three different types of licenses you can choose from to start working with Microsoft Fabric:
1. Microsoft Fabric trial
It's free for two months and you need to use your organization email. Personal email doesn't work. Please find how you can activate your free trial
2. Power BI Premium Per Capacity (P SKUs)
If you already have a Power BI premium license you can work with Microsoft Fabric.
3. Microsoft Fabric Capacity (F SKUs)
With your organizational Azure subscription, you can create Microsoft Fabric capacity. You will find more details about Microsoft Fabric licenses
We will go through the steps in detail on how Microsoft Fabric capacity can be provisioned from Azure Portal.
Step 1: Please login to the Azure Portal and find Microsoft Fabric from your organization's Azure Portal as shown below in Fig 1.
Step 2: To create the Fabric capacity, the very first step is to create a resource group as shown in Fig 2
Step 3: To create the right capacity you need to choose the resource size that you require. e.g. I have chosen F8 as shown in the below figure 3
You will find more capacity details in this Microsft blog post.
Step 4: As shown below in Fig 4, before creating the capacity please review all the information you have provided including resource group, region, capacity size, etc., and then hit the create button.
When it's done you will able to see Microsoft Fabric Capacity is created (see below fig 5)
To explore the Microsoft Fabric please browse through the site and you will find the capacity you just created finally and the home page will look like below in Fig 7
