Zorluk: OrtaReliability, Predictability, and Disaster Recovery

A hospital system deploys its patient monitoring application on Microsoft Azure. The system must be designed to withstand localized hardware failures, automatically recover from software faults, and maintain service continuity even during major regional outages.

Which cloud concept represents the overall ability of an application to recover from failures and continue to function under these conditions?

  1. A
    High Availability
  2. B
    Disaster Recovery
  3. ReliabilityCevap
  4. D
    Elasticity

Cevap

Reliability
Reliability is defined as the capability of a system to recover from failures and continue to function. It is a broad cloud concept that incorporates both high availability (to mitigate local failures) and disaster recovery (to mitigate catastrophic or regional failures).

Adım Adım Çözüm

1
Identify the core requirements from the scenario.
The application must withstand local hardware/software faults and major regional failures.
Understanding the scope of the failures to recover from helps determine the cloud concept that encompasses both local resiliency and regional recovery.
2
Compare cloud concepts that define failure recovery.
While high availability addresses localized faults and disaster recovery addresses regional failures, reliability is the overarching cloud benefit that ensures a system can recover from any failure and continue functioning.
Analyzing the relationship between reliability, high availability, and disaster recovery leads to the correct terminology.

Anahtar Kavram

Reliability in Azure represents the ability of a system to recover from failures and continue to function. It encompasses both high availability (resiliency within a region) and disaster recovery (resiliency across regions).
