 ## Introduction 
 
-In this module you are guided through a series of units that enable you to migrate an existing workload from an on-premises or cloud environment to Azure. It covers the migration of the compute to an Azure Virtual Machine and the data to Azure Database for PostgreSQL. The application is a cloud-agnostic sample application that is a stand-in for any real-world application prepared for migration to the cloud. You explore the value of shifting from a self-hosted environment, such as from a self-managed database to a fully managed database offering and from bare-metal compute to cloud-hosted virtual machines with the benefit of a full suite of security and identity controls provided by Azure, such as Microsoft Entra ID. You explore the benefits of managing resources in the cloud from a cost and performance perspective. You learn how to precisely calculate and manage costs before and after deployment, as well as how to optimize performance from both a compute and a data perspective. 
+This module guides you through the migration of an existing workload from an on-premises or cloud environment to Azure. It covers the migration of the compute to an Azure virtual machine (VM) and the data to Azure Database for PostgreSQL. The application is a cloud-agnostic sample that's a stand-in for any real-world application that's prepared for migration to the cloud.
+
+In this unit, you explore the value of making the following transitions with the benefit of a full suite of security and identity controls that Azure provides:
+
+- Shifting from a self-hosted environment (such as from a self-managed database) to a fully managed database offering
+- Shifting from bare-metal compute to cloud-hosted VMs
+
+You also explore the benefits of managing resources in the cloud from a cost and performance perspective. And you learn how to precisely calculate and manage costs before and after deployment, along with how to optimize performance from both a compute and a data perspective.
