+==== Creating a New Software Application ====
 Use the WorkXpress Cloud Management Portal to create a new software application.  In the upper right hand corner, choose "Add" and then select whether you are creating a development, testing, or production application.  The resulting popup window will guide you through each of the choices necessary to create your software, platform, and infrastructure.

 Also note that if you use the WorkXpress Store (www.workxpress.com/store) to purchase your application, the Store will create the new software application on your behalf, and you will simply find it in your list of available software applications upon logging into your WorkXpress Cloud Management Portal.
-===== WorkXpress Installation Topography =====
+==== WorkXpress Installation Topography ====
 Sometimes it may be helpful to create more advanced installations of WorkXpress.  For example, a large organization may want a single tenant application to support many users, and so installs it on a cluster of virtual appliances.  In a different example, a software ISV may want a single virtual appliance setup as a multi-tenant environment within which they can support many customers applications efficiently.  In all cases, a knowledge of WorkXpress installation topograhy options is important.

-==== Application ====
+=== Application ===
 An application is any unique software program you are developing, testing, or using in production.  See [[201:application_lifecycle_management|Application Lifecycle Management]] for additional details.
-==== Virtual Appliance ====
+=== Virtual Appliance ===
 A virtual appliance is the functional equivalent of a single computer server, except that it is defined by software rather then by a physical piece of hardware.  Server virtualization allows many virtual appliances to exist on the same piece of physical hardware or to be spread across multiple physical servers.  Virtual appliances are a fundamental component of cloud computing because they are abstracted from the underlying hardware.
-==== Cluster ====
+=== Cluster ===
 A cluster is one or many virtual appliances working together to serve the same application or set of applications.

 This concludes our lessonab about the WorkXpress Cloud Management Portal.  Now, you have all the knowledge you need to begin to experiment with WorkXpress; however, you will likely need to further your understanding of the WorkXpress Build Tools, by beginning with [[start:the_tools_of_workxpress|The Block Creator]].  Continue forward, Cloud Master!
