Review for Critical Dependencies
Important:The product name for this user guide has changed from Foundation and Cloudscape to Business Service Discovery and Migration Planning. Previous UI pages known as Foundation have changed to Business Service Discovery. Previous UI pages known as CloudScape have changed to Migration Planning.
Once you have refined and confirmed an Application Stack, it is important to review the connectivity data for critical dependencies. These are dependencies that would dictate a change in Application Stack membership (e.g. a workload that needs to be moved into the stack you are reviewing).
For instances where there is connectivity that is critical and noteworthy but does not dictate a change in stack membership, you may choose to document this information for planning purposes. This can include Reporting, BI, or Data Transformation services that leverage database connectivity into these Application Stacks. There are several options available to view connectivity for this purpose:
| • | Workload Based Visualizations |
| • | Application Stack Based Visualizations |
| • | View All Connections |
When you select an Application Stack in Add Intelligence >> All Applications or when you are in the View Individual Application Stack view, the bottom right hand section of the page provides a workload based visualization. Expand the visualization to provide more working area and use the visualization controls to show All connectivity that is Critical.
This provides an easy way to see workload to workload connectivity. You can click on any segment to view the details specific to that relationship. Make sure to use the column chooser to make sure you include application and process information. Review the connectivity to determine if any of it requires a change in Application Stack membership or if something that is noteworthy and must be somehow accounted for in your migration plan.
Tip:You are typically looking for “critical” connectivity such as Oracle, MySQL, MSSQL or known application traffic such as SAP.
Application Stack Based Visualizations
When viewing the Add Intelligence >> View Individual Application Stacks page, you have the option to view Dependent Stacks (from visualization control). This provides a visualization of all stack-to-stack connectivity relative to the individual stack you are currently viewing. Use the visualization controls to filter out infrastructure services such as Active Directory, Antivirus, etc. You can then focus on true application to application connectivity.
From here you can select any Application Stack to Application Stack segment that is interesting or that requires further investigation. By default, this will return a listing of the host to host connectivity that exists between these two stacks.
You can switch this to a Protocol view to review from this basis. Again you are typically looking for “critical” connectivity such as Oracle, MySQL, MSSQL or known application traffic such as SAP. If you do see a protocol that is critical or interesting, you can View Details to drill into this and see the specific host to host connectivity for this protocol. This will also list the application and processes associated with the connectivity adding additional context to your review.
Continue reviewing these Application Stack to Application Stack relationships until you are satisfied that there is nothing that would dictate a change in Application Stack membership.
When viewing the Add Intelligence >> View Individual Application Stacks page you have the option to View All Connections (top left). This provides a table summary of all connectivity specific to that Application Stack and includes three levels of drill down.
The View All Connections option 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. Use this option to view connectivity coming into or out of the licensed environment.
For example, you can use this dialog box to determine if an Application Stack is Internet facing. In this case you will see connectivity coming in from the RISC-unknown-internet location.
