Assess Calculated Application Output

The Applications tabs provide detailed information about the applications in a project and the dependencies among and between the applications and compute instances.

The information on the Applications pages can help determine which applications and compute instances should be assigned to each move group for migration to the cloud.

Steps

Navigate to the Application List tab.
Click on any analyzed application in the list.
sidebar. Consider the following:
In the Inventory section:
Does the list of compute instances appear accurate?
Should any compute instances be moved to alternative applications to reduce risk during migration?
In Network Throughput:
View throughput from an application to IP addresses that are outside the application.
Are there greater dependencies on some applications than others?
See the Client Dependencies and Server Dependencies tabs in the Inventory section for more details.
In App to Other Apps:
View the top 10 network services by traffic.
Are there any undefined ports to be resolved?
See the Detailed Network Data tab in the Inventory section for more details.
In App to VMs:
For compute instances, which ports might need to be opened on the firewall if you move this application?
Begin to determine bandwidth requirements.
In App to Internal:
In the data center, which ports might need to be opened on the firewall if you move this application?
Begin to determine bandwidth requirements from the cloud to the data center.
In App to External:
View the number of compute instances and throughput rates to public IP addresses.
Are there any network services that need access that you didn't previously know about?
In App to Self:
What services are used between devices within the same application?
If you are considering splitting up the application, are there devices that exchange a lot of information that you want to keep together to reduce bandwidth requirements?
Click the Client Dependencies tab.
sidebar. Consider the following:
In Throughput Summary by Client Application:
These are the clients that depend on the application to serve information (this application acts as a server).
Use this information to help identify the correct network adaptor type to select for the bandwidth.
Use this information to determine the correct bandwidth plan needed for traffic going from the public cloud to on-premise.
Example questions to consider:
If there are 5 dependencies, do you size for all five at maximum at the same time? Do I need to pay for more bandwidth, even if I won’t use it most of the time? Is the bandwidth high in the data center just because it’s available? Am I ok with higher latency?
In Service Details by Application
Which ports need to be open to allow the applications to communicate?
What kinds of applications are communicating with each other, and what types of communication are they using?
For example, you might want to identify backups that aren't being migrated to the cloud because a different solution is planned for backups.
In Service Details by Compute Instance
Get details about which compute instances are talking to each other.
Use the information to start building your move groups and decide what to move together.
Based on client IP addresses, which subnets need to be able to reach this application?
Which client compute instances rely on this application and might need to move together with this application?
Click on the Server Dependencies tab.
sidebar. Consider the following:
In Throughput Summary by Server Application:
These are applications that act as a server to the application being viewed.
Is it possible to have native cloud services (or other solutions in the target location) to replace what this application depends on?
What network adaptor type and bandwidth plan are required?
In Service Details by Application:
Which ports need to be open to allow the applications to communicate?
What kinds of applications are communicating with each other, and what types of communication are they using?
In Service Details by Compute Instance:
Which subnets need to be able to reach this application?
Which server applications interact with this application and might need to move together with this application?
Click Detailed Network Data tab.
sidebar. Consider the following:
In Network Conversations and Endpoints:
Use this data to for your own custom analysis
For example, identify subnets and count the number of devices in each subnet. if there are a large number of dependent devices, are they all coming from the same subnet (same department)?
Navigate to the Applications Analysis Summary tab.
sidebar. Consider the following:
In the section Compute Instances in Each Application:
Verify that the results of the dependency calculations appear as expected.
Do changes need to be made to the composition of the applications?
For example, are there applications that span multiple environments or locations that should divided into multiple applications rather than a single one?
In Network Throughput:
Does this high-level view of the devices that belong to the analyzed applications seem appropriate?
For example, do the internal and external communication rates appear correct?
Note
The nodes in the graphical chart are not clickable.
Change the chart view to see a table version of the data.
In Application Top Talkers:
Which applications have the most communication, indicating they might require particular care when being moved?
In Application Throughput by network services:
How do the analyzed applications talk to each other?
Are any applications isolated, with no dependencies, so they might be easier to move?
Do any applications have complex dependencies, so they will be more challenging to move and require further assessment?
Change the chart view to see a table version of the data.
To view more details about an application, click on any application in the Compute Instances... section.
If you determine that changes need to be made to any applications, modify those applications then create move groups.
