Cloud Architect Design Tool (CADT) provides version management for application architectures, which allows you to view architecture history and deploy previous versions.
Procedure
-
Open the application architecture in the canvas and open the Resource List. After a successful deployment, the CADT console canvas displays the deployed architecture topology, including resources such as Virtual Private Cloud (VPC), vSwitch, Elastic Compute Service (ECS), Server Load Balancer (SLB), Elastic IP Address (EIP), and security groups. A green check mark on each component indicates that it is ready. The Resource List at the bottom of the page displays the name, type, billing method, resource ID, status, and update time for all created resources. The status of all resources is Running. The Earlier Versions and Release All Resources buttons appear in the lower-right corner of the page. After the application is deployed, a Deployment Succeeded message appears at the top of the CADT interface. Click the Resource List button at the bottom of the architecture diagram to expand the list of deployed resources.
-
Click Earlier Versions.
-
A version timeline appears at the bottom of the canvas. On this timeline, you can view the version history of the application architecture. Each node on the timeline shows the version number and its creation time.
-
Click a version number to view the corresponding application architecture diagram.
-
To revert to a previous version, click its version number and then click Create Based on This Version to load that version onto the canvas. Click the target version number (for example, Version: 1), and then click Create Based on This Version in the menu that appears. After you click the target version number, click Create Based on This Version in the menu that appears. The canvas displays the application architecture topology, showing the connections between resources such as EIP, VPC (CIDR: 192.168.0.0/16), vSwitch, a security group, ECS (2 vCPU 4 GiB), and ApsaraDB RDS (2 vCPU 4 GiB). The application architecture displayed on the canvas is in the Singapore region. From top to bottom, the diagram shows an EIP, a VPC (192.168.0.0/16), a vSwitch (192.168.0.0/24), an ECS instance (2 vCPU 4 GiB) within a security group, and an ApsaraDB RDS instance (2 vCPU 4 GiB). Lines between the components represent the network topology.
-
Save the application, set the ApplicationName, click Deploy Application, and then follow the on-screen instructions to complete the deployment.
