-## Cobalt 100 Arm-based processor
+# Azure Cobalt 100 and NGINX overview
 
-Azure’s Cobalt 100 is built on Microsoft's first-generation, in-house Arm-based processor: the Cobalt 100. Designed entirely by Microsoft and based on Arm’s Neoverse N2 architecture, this 64-bit CPU delivers improved performance and energy efficiency across a broad spectrum of cloud-native, scale-out Linux workloads. These include web and application servers, data analytics, open-source databases, caching systems, and more. Running at 3.4 GHz, the Cobalt 100 processor allocates a dedicated physical core for each vCPU, ensuring consistent and predictable performance. 
+This section introduces Azure’s Cobalt 100 Arm-based processor and the NGINX options you can use in this Learning Path.
 
-To learn more about Cobalt 100, refer to the blog [Announcing the preview of new Azure virtual machine based on the Azure Cobalt 100 processor](https://techcommunity.microsoft.com/blog/azurecompute/announcing-the-preview-of-new-azure-vms-based-on-the-azure-cobalt-100-processor/4146353).

 ## NGINX
 
-NGINX is a high-performance, open-source web server, reverse proxy, load balancer, and HTTP cache. Originally developed by Igor Sysoev, NGINX is known for its event-driven, asynchronous architecture, which enables it to handle high concurrency with low resource usage.
+NGINX is a high-performance, open-source web server, reverse proxy, load balancer, and HTTP cache. Known for its event-driven, asynchronous architecture, NGINX handles high concurrency with low resource usage.
 
 There are three main variants of NGINX:
-- **NGINX Open Source**– Free and [open-source version available at nginx.org](https://nginx.org)
-- **NGINX Plus**- [Commercial edition of NGINX](https://www.nginx.com/products/nginx/) with features like dynamic reconfig, active health checks, and monitoring.
-- **NGINX Unit**-  A lightweight, dynamic application server that complements NGINX. [Learn more at unit.nginx.org](https://unit.nginx.org/).

 ## Introduction
 
-There are several ways to create an Arm-based Cobalt 100 virtual machine : the Microsoft Azure console, the Azure CLI tool, or using your choice of IaC (Infrastructure as Code). In this section, you will use the Azure console to create a virtual machine with Arm-based Azure Cobalt 100 Processor. 
+There are several ways to create an Arm-based Cobalt 100 virtual machine: the Microsoft Azure portal, the Azure CLI, or your preferred infrastructure as code (IaC) tool. In this section, you use the Azure portal to create a virtual machine with the Arm-based Azure Cobalt 100 processor.
+
+This Learning Path focuses on the general-purpose virtual machines in the D-series. For further information, see the Microsoft Azure guide for the [Dpsv6 size series](https://learn.microsoft.com/en-us/azure/virtual-machines/sizes/general-purpose/dpsv6-series).

+## Create an Arm-based Azure virtual machine
 
-#### Create an Arm-based Azure Virtual Machine 
+Creating a virtual machine based on Azure Cobalt 100 is similar to creating any other virtual machine in Azure. To create an Azure virtual machine, launch the Azure portal and navigate to **Virtual Machines**
 
-Creating a virtual machine based on Azure Cobalt 100 is no different from creating any other virtual machine in Azure. To create an Azure virtual machine, launch the Azure portal and navigate to "Virtual Machines".
-1. Select "Create", and click on "Virtual Machine" from the drop-down list.
-2. Inside the "Basic" tab, fill in the Instance details such as "Virtual machine name" and "Region".
-3. Choose the image for your virtual machine (for example, Ubuntu Pro 24.04 LTS) and select “Arm64” as the VM architecture.
-4. In the “Size” field, click on “See all sizes” and select the D-Series v6 family of virtual machines. Select “D4ps_v6” from the list.
+- Select **Create**, then choose **Virtual machine** from the drop-down list
+- In the **Basics** tab, fill in instance details such as **Virtual machine name** and **Region**
+- Choose the image for your virtual machine (for example, Ubuntu Pro 24.04 LTS) and select **Arm64** as the VM architecture
+- In the **Size** field, select **See all sizes**, choose the **D-series v6** family of virtual machines, then select **D4ps_v6**

-5. Select "SSH public key" as an Authentication type. Azure will automatically generate an SSH key pair for you and allow you to store it for future use. It is a fast, simple, and secure way to connect to your virtual machine.
-6. Fill in the Administrator username for your VM.
-7. Select "Generate new key pair", and select "RSA SSH Format" as the SSH Key Type. RSA could offer better security with keys longer than 3072 bits. Give a Key pair name to your SSH key.
-8. In the "Inbound port rules", select HTTP (80) and SSH (22) as the inbound ports. The default port for NGINX when handling standard web traffic (HTTP) is 80.
