Microsoft Azure Fundamentals (AZ-900)Describe cloud conceptsEasy
A small startup is developing a new online photo editing service. They anticipate varying user loads throughout the day, with peak usage during evenings and weekends. They need a cloud service that automatically adjusts computing resources to meet demand without manual intervention. Which cloud characteristic is most critical for this requirement?
- AHigh Availability
- BBroad Network Access
- CMeasured Service
- DRapid Elasticity
Show answer & explanationAnswer & explanation
Correct answer: D. Rapid Elasticity
Rapid Elasticity is the ability of cloud computing resources to scale up or down quickly and automatically in response to demand. This ensures that the online photo editing service can handle peak loads efficiently and reduce costs during low usage periods.
Why the other options are wrong
- A. High availability ensures the service remains operational, but doesn't specifically address automatic resource scaling for fluctuating demand.
- B. Broad network access allows services to be available over the network, but doesn't relate to dynamic resource adjustment.
- C. Measured service refers to the ability to monitor and charge for resource usage, not the automatic scaling of resources.
Rapid Elasticity
The ability of cloud computing resources to be provisioned and de-provisioned quickly and automatically to scale up or down in response to fluctuating demand.
- Automated scaling of resources
- Handles unpredictable workloads
- Optimizes cost and performance
Memory trick: Elastic clouds stretch to fit any load, fast!
