Application Stacks Overview

One of the primary goals for a discovery project is to organize all of the discovered (and licensed) workloads into the various Application Stacks that they support. Once this organizational work has been completed, the platform is better positioned to provide dependency, cloud costing, resource requirements, and other information from an application centric point of view. This view supports more detailed planning and analysis for Strategic IT Planning, Cloud and Data-center migration, Security reviews, CMDB updates, and other use cases.

Building Application Stacks is the process of reviewing and refining the automatically generated application stacks (AutoApp_xxx), taking system dependencies, input from application teams, best practices, and other factors into account. There is not necessarily one way to approach this process, however this document will outline some best practices for application review and refinement. The end result of this effort should be a set of application stacks that most closely represent the source environment and provide the vantage point needed to support the desired outcome(s).

How Are App Stacks Built?

The Foundation and CloudScape platform joins servers into groups based on the collected connectivity and process information. There are different group types the platform will create automatically whose definitions can be found on our Glossary page under the subsection “Group Definitions”

How to View Connectivity

All of the processes outlined below are completed using the following two pages of the portal:

Add Intelligence >> All Applications 
Add Intelligence >> View Individual Application Stacks 

Connectivity can be visualized by working in and expanding the right side frame on both of these pages. This includes providing the ability to visualize critical or all connectivity as well as viewing connectivity internal to the application stack, external to the application stack, or both (all). When viewing the Add Intelligence >> View Individual Application Stacks page you also have two additional options for viewing and navigating connectivity information:

View All Connections (top left)—Provides a table summary of all connectivity and includes three levels of drill down
Dependent Stacks (from visualization control)—Provides a visualization of all stack-to-stack connectivity relative to the individual stack you are currently viewing.

Tip:The View All Connections can be an important way to view connectivity because it is NOT limited to connectivity between licensed nodes. The visualizations are limited to connectivity between licensed nodes with the exception of the RSG-Out Of Scope Services group.

Tip:In any visualization you can click on a line segment to view the details specific to that relationship whether it be workload to workload, or application stack to application stack.
