AWS Cloud Benefits: Speed and Scalability vs On-Premises
A retail company is building a new mobile app. The company is evaluating whether to build the app at an on-premises data center or in the AWS Cloud. Which of the following are benefits of building this app in the AWS Cloud? (Choose two.)
Community Votes
100% of anonymous learners picked answer BD. Votes are pick records left by other test-takers — they are not the verified answer.
Community Insight
The exam tests the distinction between capital expenditure (CapEx) and operational expenditure (OpEx), highlighting that cloud adoption prioritizes speed-to-market and flexible scaling over physical control.
This question evaluates the core benefits of migrating to AWS, specifically focusing on operational agility and elasticity compared to traditional on-premises infrastructure.
Candidates often select A because they misunderstand the financial model; cloud computing eliminates large upfront capital expenses in favor of pay-as-you-go variable costs.

Expert Analysis
Why the Answer Is Correct
Building a mobile app in the AWS Cloud offers significant advantages in time-to-market and resource management. Option B is correct because AWS provides immediate access to tools and services, allowing developers to prototype and deploy new projects rapidly without provisioning hardware. Option D is correct because AWS auto-scaling capabilities allow applications to handle traffic spikes instantly, ensuring performance as popularity grows.Why the Other Options Are Wrong
Option A is incorrect because it describes the traditional on-premises model (high CapEx, low variable cost). The cloud model reverses this with low upfront costs and high variable costs based on usage. Options C and E are incorrect because AWS operates on a shared responsibility model; customers do not have physical access to or control over the data centers, racks, or power supplies managed by AWS.Community Comment Notes
Community consensus strongly supports BD. One user noted 'BD are correct answers,' while another clarified that 'a large, upfront capital expence en low variable expence' is actually a benefit of on-premises, not cloud. Another comment asked why B is chosen over E, reinforcing that physical location control is not a cloud benefit.Exam Strategy
Always distinguish between CapEx and OpEx when answering cloud economics questions. Remember that 'control' options usually refer to physical infrastructure, which is always an on-premises benefit, never a cloud one.
Frequently Asked Questions
Is A a benefit because variable expenses are low?
No. Cloud has LOW upfront capital expense but HIGH variable expenses based on usage. A describes on-premises.
Can I choose specific data centers for physical security?
No. You cannot control physical security or rack location in AWS; this is managed entirely by the provider.
