Question
An organization wants to duplicate critical system components to enhance reliability and mitigate single points of failure. Which design consideration should the organization use?
A. Redundancy
B. Backups
C. Latency
D. Security
Answer
A. Redundancy
Explanation
Redundancy is a critical design consideration in cloud computing, particularly for organizations aiming to enhance reliability and mitigate single points of failure. Here’s a detailed explanation:
- Definition: Redundancy involves duplicating critical components or functions of a system to increase its reliability. In cloud architecture, this means having multiple instances of resources, services, or data centers.
- Purpose: The primary goal of redundancy is to ensure continuous operation of systems even if one component fails. This directly addresses the organization’s desire to “enhance reliability and mitigate single points of failure.”
- Implementation in Google Cloud:
– Compute Engine: Use multiple instances across different zones.
– Cloud Storage: Utilize multi-regional storage for data redundancy.
– Cloud SQL: Implement high availability configuration with standby instances.
– Load Balancing: Distribute traffic across multiple instances or regions. - Benefits:
– High Availability: Ensures systems remain operational during failures.
– Fault Tolerance: Allows the system to continue functioning when components fail.
– Disaster Recovery: Facilitates quick recovery in case of major outages. - Comparison with other options:
– Backups (B): While important, backups are more about data preservation and recovery, not real-time reliability.
– Latency (C): Refers to delay in data transfer, not directly related to system reliability.
– Security (D): Critical, but not specifically aimed at enhancing reliability or mitigating single points of failure.
For the Google Cloud Digital Leader certification, understanding redundancy as a key design principle is crucial. It demonstrates knowledge of how to architect reliable and resilient cloud systems, which is a fundamental concept in cloud computing and Google Cloud services.
