 ## Considerations for moving to Azure Lab Services
 
-The key factors when migrating from physical labs to Azure Lab Services are:
+When you migrate physical labs to Azure Lab Services, you should consider the following aspects:
 
-- The lab structure: single-purpose labs versus shared labs
-- Lab software requirements
-- Lab hardware requirements
+- What is the lab structure? Are labs used for different purposes (shared lab), such as multiple classes, or are they dedicated (single-purpose lab)?
+- What are the software requirements for the lab?
+- What are the lab hardware requirements? A shared lab has to accommodate the needs for all usage scenarios and therefore has higher requirements.
 
-The software and hardware requirements for a lab depend on the lab structure. A shared lab has to accommodate the needs for all usage scenarios and therefore has higher requirements.
+To optimally benefit, you need to reassess the lab and image contents as a whole. It's not recommended to reuse the same lab image from your physical lab as-is.

 This information is needed to choose the appropriate VM size when you create a lab and to set up the image on the template VM. Learn more about [VM sizing in Azure Lab Services](./administrator-guide.md#vm-sizing).
 
-To ensure that you choose the appropriate VM size, we recommend starting with the minimum VM size that meets the hardware requirements for your applications.  Then, have faculty connect to a lab VM to validate common workloads that students will perform to ensure the performance and experience is sufficient.  It’s helpful to refer to the [Class Types](./class-types.md), which show real-world examples of how to set up applications for classes along with the recommended VM size.

 Also, [Azure Compute Gallery](./how-to-use-shared-image-gallery.md) is useful for creating and storing custom images. A compute gallery enables you to create an image once and reuse it to create multiple labs.
 
+## Conclusion
+
+Azure Lab Services provides many benefits for optimizing the cost of running your labs, simplifying set-up and maintenance, and having fine-grained access control. To optimally benefit, it's recommended to structure your labs in Azure Lab Services to have a single purpose. For example, create a separate lab for each classroom training.
