A company plans to deploy a new application that stores user profile photos in an Azure Blob Storage account. The architecture design requires the storage solution to remain available if a single datacenter within the primary region suffers a complete outage. The design does not require replication to a secondary region, and the company wants to minimize storage costs. Which redundancy option should you recommend for the storage account?
- Zone-redundant storage (ZRS)Cevap
- BLocally redundant storage (LRS)
- CGeo-redundant storage (GRS)
- DRead-access geo-redundant storage (RA-GRS)
Cevap
Zone-redundant storage (ZRS) is the recommended option because it replicates data synchronously across three availability zones in the primary region, protecting against datacenter outages without the cost of regional replication.
Zone-redundant storage (ZRS) replicates data synchronously across three Azure availability zones in the primary region. This ensures that the data remains available even if a single datacenter (zone) experiences a complete outage, without incurring the higher cost of geo-replication.
Adım Adım Çözüm
Anahtar Kavram
Selecting the appropriate Azure storage redundancy level (LRS vs. ZRS vs. GRS) based on availability requirements and cost constraints.
