What is Zone-Based Control?

Zone-Based Control is a feature provided by CB-Spider in Cloud-Barista, allowing resource creation and management not only in the Default Zone within a single Connection but also in other Target Zones. For more, Check the Zone-based Control wiki document.

Environment Setup

- CB-SPIDER: 0.10.1
- CSP: AWS
- Region: us-east-2
- Default Zone: us-east-2a (United States, Ohio)
- Target Zone: us-east-2b (United States, Ohio)
- VM Spec: t2.micro
- VM Image: ami-00afc76f2b7273d3b
- Disk: Size - 1GB / Type - gp2

Test Cases

Case 1: Check Resource Zone Information

Objective:

Verify the zone information of the provisioned resources(Subnet, Disk, VM).

Steps:

1. List all resources created in the default and target zones.
2. Ensure the zone information matches the expected configuration.

Expected Result:

• Resource details include accurate zone information.

Examples:

Figure 1: VPC/Subnet Management

Figure 2: Disk Management

Figure 3: VM Provisioning Info

Case 2: Default Zone Test

Objective:

Test resource provisioning in the default zone (us-east-2a).

Steps:

1. Create a subnet s1 and disk d1 in the default zone (us-east-2a).
2. Create a Security Group for s1.
3. Provision a VM in the subnet s1.
4. Attach the disk d1 to the VM.
5. Detach the disk d1 from the VM.

Expected Result:

• Subnet s1 and disk d1 are successfully created in the default zone (us-east-2a).
• VM1 is successfully created in the us-east-2a zone.
• Disk d1 is successfully attached to the VM1.
• Disk d1 is successfully detached from the VM1.

Examples:

Figure 5: Disk Detach from Default Zone

Case 3: Target Zone Test

Objective:

Test resource provisioning in the target zone (us-east-2b).

Steps:

1. Create a subnet s2 and disk d2 in the target zone (us-east-2b).
2. Create a Security Group for s2
3. Provision a VM2 in the subnet s2.
4. Attach the disk d2 to the VM2.
5. Detach the disk d2 from the VM2.

Expected Result:

• Subnet s2 and disk d2 are successfully created in the target zone (us-east-2b).
• VM2 is successfully created in the us-east-2b zone.
• Disk d2 is successfully attached to the VM2.
• Disk d2 is successfully detached from the VM2

Examples:

Figure 6: Disk Attach to Target Zone

Figure 7: Disk Detach from Target Zone

Case 4: Verify Zone Mismatch Error Message

Objective:

Validate error handling when there is a zone mismatch.

Steps:

1. Attempt to interaction with a resource in an incorrect zone.
2. Attempt to attach d1 (in us-east-2a) to VM2 (in us-east-2b) using the API / CLI
3. Observe the error message returned by the system.

API Details:

• Method: PUT
• Endpoint: `http://localhost:1024/spider/disk/aws-ohio-disk-1/attach
• Request Body:

  {
    "ConnectionName": "aws-config01",
    "ReqInfo": {
      "VMName": "aws-ohio-vm-2"
    }
  }

Expected Result:

• System Should return a Zone Mismatch Error response, clearly indicating that the disk and the VM are not in the same availability zone.

Example Response:

{
  "message": "InvalidVolume.ZoneMismatch: The volume 'vol-0fb0eede632787658' is not in the same availability zone as instance 'i-08bdefda0ac12fef5'\nstatus code: 400, request id: 60e134ec-8477-4679-88a8-a70d057a62c8"
}
