Difficulty: MediumUnderstand concepts of cloud economics

A digital marketing agency, ApexCampaigns, runs high-volume ad-serving applications. The traffic to these applications fluctuates unpredictably based on client campaign launches, with massive surges for a few days followed by periods of low activity. The agency is planning to migrate its infrastructure from an on-premises colocation facility to AWS to improve cost efficiency. Which two of the following options describe the cloud economic benefits of migrating this workload to AWS? (Select two.)

  1. The shift from capital expenses (CapEx) to variable operating expenses (OpEx) eliminates the need for large upfront infrastructure investments.Answer
  2. Leveraging cloud elasticity allows the agency to dynamically scale compute capacity down during low-traffic periods to avoid paying for idle resources.Answer
  3. C
    The agency can completely eliminate variable operating expenses (OpEx) by purchasing On-Demand Instances to handle traffic surges.
  4. D
    The agency should overprovision infrastructure to permanently match maximum campaign peak demands to guarantee scalability at the lowest cost.
  5. E
    The agency will receive unlimited Free Tier benefits for all running ad-serving servers as long as they manage them using AWS Organizations.

Answer

The correct options are the statements regarding the shift from capital expenses (CapEx) to variable operating expenses (OpEx) which eliminates upfront infrastructure investments, and leveraging cloud elasticity to dynamically scale compute capacity down during low-traffic periods to avoid paying for idle resources.
The correct answers highlight the shift from capital expenses to operating expenses and the use of elasticity. Shifting from CapEx to OpEx allows the agency to avoid large upfront payments for hardware they may not fully utilize. Utilizing cloud elasticity ensures that capacity scales down during low-traffic periods, preventing charges for idle resources.

Step-by-Step Solution

1
Analyze the business scenario and identify the workload pattern.
The workload fluctuates unpredictably, with massive spikes during marketing campaigns and low activity in between.
Understanding the workload pattern helps in determining how cloud economics can optimize costs.
2
Evaluate the options against AWS cloud economics principles, specifically CapEx vs OpEx and elasticity.
The shift from CapEx to OpEx reduces upfront costs, and elasticity matches resources to demand to prevent paying for idle capacity.
These are two core economic benefits of AWS that directly address the agency's goals of cost efficiency and managing fluctuating traffic.

Key Concept

AWS Cloud economics benefits, focusing on the shift from capital expenses (CapEx) to operating expenses (OpEx) and the cost efficiency driven by cloud elasticity.
