Difficulty: EasyUnderstand concepts of cloud economics

A wellness startup, FitPulse, is launching a new mobile workout application. Instead of purchasing physical servers and hosting them in a private data center, the company decides to build its backend on AWS to pay only for the compute resources it consumes on an hourly basis.

Which of the following economic benefits of the AWS Cloud does this decision directly represent?

  1. A
    Trading operating expenses for capital expenses to lower monthly billing costs
  2. B
    Adopting a monolithic architectural design to eliminate cloud operational overhead
  3. Trading capital expenses for operating expensesAnswer
  4. D
    Focusing on vertical scalability instead of elasticity to maintain fixed server pricing

Answer

Trading capital expenses for operating expenses
By utilizing AWS, the startup avoids large upfront investments in physical infrastructure (capital expenses) and instead pays for services as they are consumed (operating expenses). This model lowers the barrier to entry and aligns ongoing costs with usage.

Step-by-Step Solution

1
Analyze the financial difference between on-premises and AWS models in the scenario.
On-premises deployment requires buying physical hardware upfront (capital expenses / CapEx), whereas AWS allows paying for resources as they are used (operating expenses / OpEx).
Understanding what financial transaction type is being replaced by cloud adoption.
2
Evaluate the choices to identify the concept that maps to replacing upfront hardware purchases with ongoing hourly consumption costs.
Trading capital expenses for operating expenses is the correct term for this shift.
Selecting the option that matches the core economic benefit demonstrated by the startup's decision.
