Question

Difficulty: Very hardDefine the benefits of the AWS Cloud

A financial services company is planning to migrate a core application to the AWS Cloud. The application experiences predictable spikes in demand during the first three days of each month, requiring ten times the standard compute capacity. Under their current on-premises model, the company must maintain hardware provisioned for these peak loads, leading to high capital expenditures and underutilized servers for the rest of the month.

Which of the following AWS Cloud benefits directly address these operational and financial challenges? (Select TWO)

  1. Trading fixed expense for variable expense, allowing the company to pay only for the resources they consume instead of investing heavily in data centers and servers.Answer
  2. B
    Eliminating operational expenses by converting all variable resource fees into fixed capital expenses to ensure long-term cost predictability.
  3. Stopping guessing capacity, ensuring the company can scale up automatically to meet the monthly three-day demand peak and scale back down during quiet periods.Answer
  4. D
    Leveraging scalability to permanently maintain maximum provisioned capacity, ensuring that the application never requires dynamic adjustment.
  5. E
    Adopting monolithic designs that bundle all components onto a single high-capacity instance to eliminate the operational overhead of distributed microservices.

Answer

The correct benefits are trading fixed expense for variable expense and stopping guessing capacity.
The correct answers are the options describing 'Trading fixed expense for variable expense' and 'Stopping guessing capacity'. Shifting from fixed to variable expenses allows the business to pay only for resources when they are actually consumed rather than investing in physical infrastructure upfront. Stopping guessing capacity allows the company to automatically scale up to handle the month-end demand spikes and scale down during the rest of the month, eliminating resource waste.

Step-by-Step Solution

1
Analyze the financial challenge in the scenario.
The company has high capital expenditures due to purchasing upfront physical hardware.
Identifying the root financial inefficiency is necessary to map it to the corresponding AWS benefit.
2
Map the financial challenge to the AWS Cloud benefit.
The benefit is 'trading fixed expense for variable expense' (or capital expense to variable operating expense).
This benefit directly replaces large upfront hardware investments with pay-as-you-go pricing.
3
Analyze the operational challenge in the scenario.
The company must provision for peak capacity, leading to severe resource underutilization for 90% of the month.
Identifying the capacity management inefficiency is necessary to map it to the corresponding AWS benefit.
4
Map the operational challenge to the AWS Cloud benefit.
The benefit is 'stopping guessing capacity'.
This benefit uses elasticity to scale up automatically during the 3-day spike and scale down afterward, eliminating underutilized idle capacity.
