Difficulty: MediumDefine the benefits of the AWS Cloud

An online event ticketing platform experiences massive, unpredictable traffic surges when tickets for major concerts go on sale. To prevent site crashes on-premises, the company had to buy and deploy excess hardware in advance, which then sat underutilized for the rest of the year. Additionally, purchasing these physical servers required significant upfront funding.

Which two benefits of the AWS Cloud directly address this company's challenges? (Select TWO.)

  1. Stop guessing capacityAnswer
  2. B
    Trade variable expense for capital expense
  3. C
    Utilize vertical scalability to dynamically scale down infrastructure during low-demand periods
  4. Trade capital expense for variable expenseAnswer
  5. E
    Consolidate applications into a tightly coupled monolithic design to minimize network overhead

Answer

The ticketing platform can address its challenges by trading capital expense for variable expense and stopping guessing capacity.
The correct benefits are stopping guessing capacity and trading capital expense for variable expense. By leveraging AWS, the ticketing platform eliminates the need to pay large upfront capital costs for servers (trading capital expense for variable expense) and no longer needs to keep idle hardware running just to handle potential traffic surges (stopping guessing capacity) because resources can scale dynamically.

Step-by-Step Solution

1
Analyze the financial and operational pain points described in the scenario.
The company faces two primary issues: significant upfront funding for physical server purchases, and underutilized hardware because they must over-provision to handle unpredictable peaks.
Understanding the specific challenges allows mapping them to the corresponding AWS Cloud benefits.
2
Evaluate the financial pain point against the AWS economic benefits.
Paying upfront for physical servers represents a capital expense. Transitioning to a model where they pay only for what they consume maps to the benefit of trading capital expense for variable expense.
Shifting from CapEx to OpEx reduces upfront risk and cash flow constraints.
3
Evaluate the capacity planning challenge against the AWS operational benefits.
Maintaining idle servers to handle traffic spikes is resolved by stopping guessing capacity. AWS allows automatic scaling to meet real-time demand, removing the need for manual pre-provisioning.
Elastic provisioning ensures applications remain available during spikes without paying for idle resources during off-peak times.
