Zorluk: OrtaReliability, Predictability, and Disaster Recovery

A multiplayer online gaming company replicates its player-profile database from a primary datacenter region in the United States to a secondary region in Europe. This replication is configured to ensure that if a major natural disaster takes the primary region completely offline, players can still access their accounts with minimal downtime. Which cloud concept is primarily illustrated by this strategy?

  1. A
    Elasticity
  2. B
    High availability
  3. Disaster recoveryCevap
  4. D
    Availability zones

Cevap

Disaster recovery
Disaster recovery refers to the policies, tools, and procedures that enable the recovery or continuation of vital technology infrastructure and systems following a natural or human-induced disaster. Replicating databases to a geographically distant secondary region to recover from a complete regional outage is a classic disaster recovery strategy.

Adım Adım Çözüm

1
Analyze the scenario requirements
The scenario describes replicating data across separate geographical regions (US to Europe) to handle a major natural disaster that takes an entire primary region offline.
This establishes the scope of the event as a catastrophic regional failure.
2
Differentiate between regional uptime (high availability) and regional recovery (disaster recovery)
Disaster recovery is designed to handle full regional failures by recovering data and operations in a different region, whereas high availability keeps systems running despite minor, local issues within a single region.
This allows us to identify the correct cloud concept.
