Microsoft Azure Fundamentals (AZ-900)Describe cloud conceptsMedium
A startup is designing a new mobile application that needs to securely store customer data and process payments. They want to minimize upfront capital expenditure and reduce the operational burden of managing servers, databases, and networking components. They are looking for a cloud characteristic that allows them to pay only for the resources they consume, without needing to invest in physical infrastructure. Which cloud characteristic is being sought?
- AFault Tolerance
- BMeasured Service
- CAgility
- DBroad Network Access
Show answer & explanationAnswer & explanation
Correct answer: B. Measured Service
Measured Service is the cloud characteristic that enables cloud systems to automatically control and optimize resource use by leveraging a metering capability. This allows providers to charge consumers only for the resources they actually consume, directly addressing the startup's need to minimize upfront costs and pay only for what they use.
Why the other options are wrong
- A. Fault tolerance ensures resilience against failures, not cost optimization based on usage.
- C. Agility refers to the speed of development and deployment, not the billing model.
- D. Broad network access refers to the availability of services over the network, not the financial model.
Measured Service
A cloud characteristic where resource usage is monitored, controlled, and reported, providing transparency for both the provider and consumer. This enables a 'pay-as-you-go' billing model.
- Resource usage is tracked and metered
- Enables pay-per-use billing
- Provides transparency and cost optimization
Memory trick: Measured service is like a utility meter for your cloud bill.
