Microsoft 365 FundamentalsDescribe cloud conceptsMedium
A global non-profit organization requires a highly available and disaster-resilient solution for its donor database. The solution must ensure that data remains accessible even if an entire regional data center experiences an outage. Which cloud benefit directly addresses this critical requirement?
- AHigh Availability
- BElasticity
- CScalability
- DGlobal Reach
Show answer & explanationAnswer & explanation
Correct answer: A. High Availability
High availability ensures that a service or application remains operational and accessible even in the event of component failures, including entire data center outages, by distributing resources across multiple fault domains or regions.
Why the other options are wrong
- B. Elasticity is the ability to automatically scale resources up or down rapidly based on demand, which is a type of scalability.
- C. Scalability refers to the ability to increase or decrease resources to handle varying demand, not necessarily to survive regional outages.
- D. Global reach refers to the ability to deploy applications in data centers around the world, which facilitates high availability but isn't the benefit itself.
High Availability
A cloud benefit ensuring that applications and services remain operational and accessible for extended periods, minimizing downtime.
- Achieved through redundancy, fault tolerance, and failover mechanisms.
- Often involves deploying resources across multiple regions or availability zones.
- Critical for business continuity and disaster recovery.
Memory trick: Cloud benefits make things reliable, flexible, and cost-effective.
