A logistics company is hosting a shipment tracking application in Azure. The application's web tier must remain operational if a power or cooling failure affects an entire datacenter facility within the primary region. Additionally, database backups must be replicated to a secondary region located hundreds of miles away to protect against regional disasters. Which Azure architectural features should the company use to meet these requirements?
- ADeploy the web tier across multiple Region Pairs and replicate database backups using Availability Zones.
- BDeploy the web tier in a Resource Group set to a different region and replicate database backups using Availability Zones.
- Deploy the web tier across multiple Availability Zones and replicate database backups using Region Pairs.Answer
- DDeploy the web tier across multiple Availability Zones and replicate database backups within the same Resource Group.
Answer
Deploy the web tier across multiple Availability Zones and replicate database backups using Region Pairs.
Deploying the web tier across multiple Availability Zones protects it from localized power or cooling outages in a single datacenter because each zone is an isolated physical location within the region. Replicating database backups using Region Pairs ensures disaster recovery protection by hosting the copies in a secondary region located hundreds of miles away.
Step-by-Step Solution
Key Concept
Azure Availability Zones provide high availability and local residency by isolating power and cooling failures within a region, whereas Region Pairs provide disaster recovery by replicating data to a secondary region at least 300 miles away.
