Question
What is an advantage of AWS cloud computing that minimizes variable costs?
A. High Availability
B. Economies of Scale
C. Global Reach
D. Agility
Answer
B. Economies of Scale
Explanation
AWS can achieve lower variable costs per unit of compute by distributing the fixed costs of building and maintaining data centers across a large number of customers. As a result, AWS can offer lower and more predictable prices to its customers, who only pay for the resources they consume.
Economies of scale refer to the cost advantages that AWS achieves by operating on a massive scale. AWS serves hundreds of thousands of customers globally, which allows it to:
- Spread Fixed Costs: AWS distributes the fixed costs of its large-scale infrastructure (e.g., data centers, hardware) across a vast customer base, reducing the per-unit cost for individual users.
- Bulk Purchasing Discounts: AWS buys hardware and software in bulk, securing significant discounts that result in lower costs for customers.
- Optimized Resource Utilization: By efficiently utilizing its resources, AWS minimizes waste and maximizes performance, further reducing costs.
These factors enable AWS to offer lower pay-as-you-go prices compared to what businesses would incur managing their own infrastructure. Customers only pay for the resources they use, and as their usage scales up or down, their costs adjust proportionally. This flexibility eliminates the need for significant upfront investments in hardware or over-provisioning resources.
Why Not the Other Options?
A. High Availability: While high availability ensures systems are operational and accessible, it does not directly impact variable costs.
C. Global Reach: Global reach refers to AWS’s ability to provide services worldwide, enhancing accessibility and reducing latency but not minimizing variable costs.
D. Agility: Agility allows businesses to quickly adapt and scale resources but is unrelated to cost minimization.
Key Takeaway
AWS’s economies of scale are a cornerstone of its cost-efficiency model. By leveraging its extensive infrastructure and customer base, AWS reduces variable expenses, making cloud computing affordable and scalable for businesses of all sizes. Understanding this concept is essential for passing the AWS Certified Cloud Practitioner CLF-C02 exam.
