Difficulty: HardDefine the benefits of the AWS Cloud

An automotive manufacturer is designing a telematics system to gather diagnostic data from 10,00010,000 connected test vehicles. The data transmission is highly irregular, peaking during daily test runs and dropping to zero overnight. The company wants to avoid purchasing dedicated physical servers that would remain idle during non-test hours, preferring a model where they pay only for the compute resources consumed during active tests. Which benefit of the AWS Cloud is directly demonstrated by this approach?

  1. Trading capital expense for variable expenseAnswer
  2. B
    Trading variable expense for capital expense
  3. C
    Increasing elasticity by provisioning static maximum capacity
  4. D
    Eliminating operational costs by deploying a monolithic database architecture

Answer

Trading capital expense for variable expense
The correct answer is trading capital expense for variable expense. By choosing to pay only for the compute resources consumed during active tests rather than buying physical servers in advance, the automotive manufacturer avoids capital expenditures (CapEx) and adopts a pay-as-you-go variable expense (OpEx) model.

Step-by-Step Solution

1
Analyze the business requirements in the scenario.
The company wants to avoid upfront purchases of physical servers (capital expense) for irregular workloads and instead pay only for resources consumed during active periods (variable expense).
Understanding the customer's financial and technical constraints is key to mapping them to the correct AWS Cloud benefit.
2
Evaluate the AWS Cloud benefits against the identified requirements.
The practice of paying only for consumed compute resources rather than investing in physical infrastructure aligns with the benefit of 'trading capital expense for variable expense'.
AWS defines this benefit as paying only when you consume computing resources and paying only for how much you consume, rather than investing heavily in data centers and servers up front.
