CLF-C02 - Cloud Concepts - Section 1.1

Define the benefits of the AWS Cloud, including economies of scale, trading capital expense for variable expense and the agility of on-demand provisioning.

Describe how AWS economies of scale lower per-unit costs over time and why trading upfront capital expense for variable, pay-as-you-go expense reduces financial risk. Recognise that on-demand provisioning delivers agility by eliminating the lead time required to procure physical hardware.

A finance lead is explaining to colleagues how the AWS Cloud changes the way the company pays for and obtains computing infrastructure compared with its old data centre. Which TWO statements correctly describe benefits of the AWS Cloud value proposition? (Select TWO.)

  • AThe company pays a variable expense for the computing resources it actually consumes instead of a large upfront capital expense Correct
  • BBecause AWS aggregates demand across very many customers, its economies of scale translate into lower pay-as-you-go prices for users Correct
  • CThe company must still purchase and own the physical servers, but AWS stores and powers that hardware inside its data centres
  • DThe company commits to a fixed three-year payment for capacity in advance regardless of how much it ends up using each month
  • EAWS guarantees that every workload will always cost less on the cloud than running an equivalent server on the company premises
The AWS value proposition replaces large upfront capital expense with variable pay-as-you-go expense and passes economies of scale on as lower prices. Moving to AWS converts fixed capital spending on owned hardware into a variable cost tied to consumption, and because AWS aggregates the usage of a huge customer base it reaches a scale that drives its per-unit costs down and lets it offer lower prices.

Why A is correct: Trading capital expense for variable expense is a core AWS benefit, so the company pays only for the resources that it consumes.

Why B is correct: Economies of scale let AWS achieve lower costs at high volume and pass those savings on through lower prices to its customers.

Why C is wrong: This sounds like a hosting arrangement, but with AWS the customer does not buy or own the underlying physical servers at all.

Why D is wrong: A mandatory fixed upfront commitment describes the old data centre model, which is the very pattern the cloud lets the company avoid.

Why E is wrong: No such blanket guarantee exists, since cost outcomes depend on the workload, and an absolute promise like this is not part of the value proposition.
