AWS Cloud Benefits: Speed and Scalability vs On-Premises

CLF-C02 By islever Editorial Last updated

Define the benefits of the AWS Cloud.

Short answer

BD Building in AWS increases project speed and provides flexibility to scale up minutes as the application becomes popular.

Question

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.)
  1. A large, upfront capital expense and low variable expenses
  2. Increased speed for trying out new projects Correct Answer
  3. Complete control over the physical security of the infrastructure
  4. Flexibility to scale up in minutes as the application becomes popular Correct Answer
  5. Ability to pick the specific data centers that will host the application servers

Key Takeaways

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.

Common mistake: 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.

    I think it must be A and D. a large, upfront capital expence en low variable expence is one of de benefit of cloud.
  3. ShaiTay 👍 2
    B and D are correct.
