Hello, Welcome to MS Q&A
Azure Key Vault is designed with multiple layers of redundancy to ensure high availability. In the event of a service disruption, Azure Key Vault can automatically failover requests to a paired region without user intervention. However, there may be instances where individual components fail, and during such times, requests could be affected temporarily.
To handle scenarios where Azure Key Vault might be unavailable, you can consider the following alternatives:
- Backup and Restore: Utilize the backup and restore feature to replicate the contents of your vault to another region of your choice.
- Secondary Vault: Store secrets and other Key Vault artifacts in a secondary vault with appropriate permissions, especially if your application requires the vault to be in the same region.
- Implementing Alerts: Set up alerts for upcoming expirations of secrets to ensure you are notified before any critical downtime.
These strategies can help mitigate risks associated with potential service outages.
For more details, you can refer to the following documentation:
