AWS Topology

You can check at a glance the connection information and status between resources connected from Route53 through Record Set, LB, Target Group, and EC2 Instance.

I. Home screen

Resource selection

 Select the resource for which you want to view connection information.

 

II. Resource selection

 1. Resource Type

 Select the type of resource. Currently, you can select from five types of resources: Hosted Zone (Route53), Record Set (Route53), Load Balancers (LB), Target Group (LB), and Instance (EC2 Instance).

 (In the future, we plan to expand to the Cloud Native Application Topology area such as API Gateway, Lambda, RDS, Cloud Front, S3, and Beanstalk.)

 2. Resource Selection

 Draw a topology graph by selecting the corresponding resource.

 3. Select table row

 Shows detailed information about the resource.

 

III. Screen Layout

 1. Selected resource information

 Shows information about the selected reference resource to display the current topology.

 2. Topology graph

 Shows connection information related to (Route53 - Record Set - LB - Target Group - EC2) based on the selected reference resource.

 3. Resource List

 Shows a list of resources represented in the topology graph.

 4. Data collection cycle

 The data used to draw the topology graph is collected in one-hour cycles.

 If new data is collected, you can update the data using the refresh button.

 

IV. Topology graph

 1. Reference resources

 The reference resources selected for drawing the topology graph via the Select Resource button can be distinguished by their background color.

 2. Issue Resources

 If there is an issue with a resource, the border of the resource will change color to identify it.

 Green: No special information about the resource

 Orange: The resource connection information is incorrect, or there is no resource connected.

 Red: The resource is in an unhealthy state.

 3. Port Information

 When an LB and an instance are connected, you can check which port it is connected to through the label.

 

V. Resource List

 1. Sorting

 You can sort the resource list by status/name.

 The default sort is status-based sort.

 2. Filter

 You can filter the list of resources by the type of resource you want.

 3. Search

 You can search for a specific resource in the resource list.

 Route 53 and Record Set can be searched by domain address, while LB, Target Group, and Instance can be searched by name. For IP, you can search by IP address.

 4. Status

 If there is an issue with the resource, the icon will change.

VI. Leveraging topology

 1. Hover

    You can view detailed information about a resource by hovering your cursor over it.

 You can also highlight only the resources linked to that resource.

 2. Click on the node

 Clicking on a resource icon will highlight only the resources related to that resource. (Fixed)

 3. Click on the resource list

 You can also click on a resource in the resource list to highlight only the resources related to that resource.

    Related resources are also sorted first in the list.

 4. Issue Resources

    You can hover over a resource with an issue to see the cause of the issue.

 The above example situation occurred because there was no LB that matched the DNS information registered in the Record Set.
