Cloud Digital Leader Why Cloud Technology Can Transform Business Practice Question

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  Scalability

  Why it's wrong here

  Scalability describes the ability to elastically provision or release compute, storage, and networking resources to match fluctuating demand. While cloud autoscaling can prevent overprovisioning and idle capacity, it does not by itself change whether a startup pays a large upfront capital expense or a per-consumption fee. A startup could pay for predictable baseline capacity with committed-use discounts and still be highly scalable; thus scalability does not explain the pay-as-you-go cost model.

• ✗

  Agility

  Why it's wrong here

  Agility emphasizes rapid application development, continuous integration/delivery, and the ability to iterate and release features quickly in response to market feedback. It addresses the startup's desire to launch quickly, but it concerns operational speed rather than the financial structure of resource acquisition. An agile team using traditional servers might still face significant upfront procurement lead time and capital costs, so agility alone does not guarantee a pay-as-you-go expenditure model.

• ✗

  Global reach

  Why it's wrong here

  Global reach refers to distributing infrastructure across multiple regions to provide low-latency access, data residency, and disaster recovery to users worldwide. Although cloud providers make this easy and can bill per region on a usage basis, global presence is a geographic and performance attribute, not a pricing or cost-structure attribute. The startup could achieve global reach through geographically dispersed data centers while still using upfront, fixed-cost infrastructure, so it does not inherently address the pay-as-you-go cost model.

• ✓

  Cost optimisation (pay-as-you-go)

  Why this is correct

  Cost optimisation, specifically the pay-as-you-go model, lets the startup convert large upfront capital expenditure on hardware into variable operating expense charged only for actual consumption. For a startup launching a new application with uncertain user demand, this avoids the financial risk of overinvesting in idle infrastructure and allows spending to grow linearly with measured usage. Pay-as-you-go is therefore the precise cloud characteristic that eliminates upfront costs and aligns spend with revenue or traffic.
