What should you implement to meet the disaster recovery requirements for the PaaS solution?

Show Suggested Answer Hide Answer
Suggested Answer: B

Scenario: In the event of an Azure regional outage, ensure that the customers can access the PaaS solution with minimal downtime. The solution must provide automatic failover.

The auto-failover groups feature allows you to manage the replication and failover of a group of databases on a server or all databases in a managed instance to another region. It is a declarative abstraction on top of the existing active geo-replication feature, designed to simplify deployment and management of geo-replicated databases at scale. You can initiate failover manually or you can delegate it to the Azure service based on a user-defined policy.

The latter option allows you to automatically recover multiple related databases in a secondary region after a catastrophic failure or other unplanned event that results in full or partial loss of the SQL Database or SQL Managed Instance availability in the primary region.

Wait, can you really rely on just one of these options?

Always On availability groups seem like overkill for some setups.

Always On availability groups seem like a solid choice, but I need to double-check if they apply to PaaS environments.

I think failover groups might be relevant here, especially since we practiced a similar question last week.

I remember studying about availability zones, but I'm not sure if they are the best option for PaaS disaster recovery.

Geo-replication sounds familiar, but I can't recall if it's specifically for PaaS solutions or more for IaaS.

Hmm, this seems like a tricky one. I'll need to think through the project lifecycle stages carefully to figure out the right document.

I think the first step might involve creating groups of interest; it makes sense to define what to work with first.

Okay, I've got a strategy here. I'll focus on how the level of aggregation could affect the visibility of demand and resource imbalances. That seems like the core issue they're getting at.
