Zorluk: OrtaAzure Regions, Availability Zones, and Region Pairs

An organization is migrating its transaction processing system to Azure. The system requires high availability to protect against localized datacenter failures and a disaster recovery plan to protect against region-wide outages. You need to evaluate the following statement:

Deploying the application across multiple Availability Zones within the primary region provides high availability using synchronous replication, while replicating data to the designated Azure Region Pair provides disaster recovery using asynchronous replication.

Is this statement true or false?

Cevap: Cevap

Cevap

True
The statement is correct because deploying across Availability Zones provides local high availability through synchronous replication, while Azure Region Pairs provide disaster recovery across long distances using asynchronous replication.

Adım Adım Çözüm

1
Analyze the requirements for high availability (HA) and disaster recovery (DR).
HA protects against localized datacenter failures, while DR protects against regional outages.
To verify if the proposed services align with the business goals.
2
Evaluate the replication type and scope of Azure Availability Zones.
Availability Zones use low-latency, synchronous replication within a single region to provide high availability.
To confirm if Availability Zones satisfy the local HA requirement.
3
Evaluate the replication type and scope of Azure Region Pairs.
Region Pairs use asynchronous replication over long distances to provide disaster recovery without impacting performance.
To confirm if Region Pairs satisfy the DR requirement.

Anahtar Kavram

The distinction between high availability using Availability Zones and disaster recovery using Region Pairs.
