5. Challenge of AKS Backup
1. Challenge of Backup Azure Disks on
AKS
This will come with difficulty as Azure
Disks will be mounted as PVC for any
deployments on Kubernetes.

6. Challenge of AKS Backup? (Cont.)
2. Challenge of Backup namespaces on
AKS
If you not tie to GitOps, how to recover
your traditional applications per
namespace on AKS when they failed.

7. Challenge of AKS Backup? (Cont.)
3. Developer experience and Cloud
Storage compatibility
- Learn new tools often have learning
curve and how you remove
boilerplate of these
- Any cloud storage compatible for
High Available?

8. Velero comes with the help of AKS Backup Challenge
- Velero helps you backup Azure
Disks even they mounted as
PVC for your applications
- Velero also help to backup the
rest deployments to Azure
Blob Storage

9. Velero comes with the help of AKS Backup Challenge (Cont.)
- When namespace failed, you can also
recover it with Velero

10. Velero comes with the help of AKS Backup Challenge (Cont.)
- The Velero developer experience (DX) is very good, you can backup any resources on AKS and
Azure Disks mounted as PVC with the single command line (CLI)
- The Velero supports Cloud provider storage likes Azure Blob Storage as a plugin (Seamless
Integration)

11. How Velero Setting Up?
- We can use Helm to install Velero with values (values.yaml)
- Config values.yaml:
https://gist.githubusercontent.com/dmakeroam/f30e692ef87ee1f22a1c03f01585eb14/raw/62f9a7bd2d6
60ec955ffe14eaff171b6a269b125/values.yaml
- Then install the Velero with the values.yaml
- Wait for 5 - 10 minutes and verify that the Velero is working fine

12. How Velero Setting Up? (Cont.)
- We need to use Azure Workload Identity to configure Velero service account in order to connect the
Azure Blob Storage for Kubernetes manifests backups and create Azure Disk Snapshots.

13. How Velero Setting Up? (Cont.)
- To read PVC as Azure Disks and get backup, we need to create a volume snapshot class

14. How Velero Setting Up? (Cont.)
- We create a blob storage account for Kubernetes manifests backup

15. How Workload Identity Works?

16. How Workload Identity Enabling on AKS?
Establishing federated identity credentials
1. Create a managed identity required for your application, in this case is velero
2. Federate the identity to your application service account (velero)

17. How Workload Identity Enabling on AKS? (Cont.)
Establishing federated identity credentials
3. Assign the required permission (role) to the identity such as for Velero, we will use “Contributor”
4. Copy the identity client ID to be used in the application service account (Velero)

18. Demo: Backup Workpress on AKS with Velero

19. Demo: Backup Workpress on AKS with Velero
1. We will use Helm to install Wordpress with values (values.yaml)
- Config values.yaml:
https://gist.githubusercontent.com/dmakeroam/46cc530120f5d069b8c4842837fd768a/raw/b5e7
a94c2f5e54a5e198fb8061b274690f16db61/wordpress.yaml
- Then install the Wordpress with the values.yaml

20. Demo: Backup Workpress on AKS with Velero (Cont.)
2. Testing the Wordpress after the deployment
3. Try to Backup the Wordpress to Azure Disk Snapshots, and Azure Blob Storage

21. Demo: Backup Workpress on AKS with Velero (Cont.)
5. Restore the Wordpress from the backup
6. Verify if the Wordpress is working properly
4. Delete the Wordpress to see if the Velero can restore data and configurations from the backup
storages
